RP506L Series
AEC-Q100 Compliant
2 A PWM/VFM Step-down DC/DC Converter with Synchronous
Rectifier for Automotive Applications
No. EC-296-210909
OUTLINE
The RP506L is a low supply current CMOS-based PWM/VFM step-down DC/DC converter with synchronous
rectifier featuring 2 A( 1) output current. Internally, a single converter consists of an oscillator, a reference voltage
unit, an error amplifier, a switching control circuit, a mode control circuit, a soft start circuit, a latch type
protection circuit, an under-voltage lockout (UVLO) circuit, a thermal shutdown circuit, and switching transistors.
The RP506L is employing synchronous rectification for improving the efficiency of rectification by replacing
diodes with built-in switching transistors. Using synchronous rectification not only increases circuit performance
but also allows a design to reduce parts count.
Power controlling method can be selected from forced PWM control type or PWM/VFM auto switching control
type by inputting a signal to the MODE pin. In low output current, forced PWM control switches at fixed
frequency rate in order to reduce noise. Likewise, in low output current, PWM/VFM auto switching control
automatically switches from PWM mode to VFM mode in order to achieve high efficiency.
Output voltage type can be selected from an internally fixed output voltage type (RP506Lxx1G/H/K/L) or an
externally adjustable output voltage type (RP506L001N/M). The output voltage accuracy of the
RP506Lxx1G/H/K/L is as high as ±1.5% or ±18 mV. The output voltage of the RP506L001N/M can be set by
using the external resistors.
Oscillator frequency can be selected from 2.3 MHz (RP506Lxx1G/H//N) or 1.2 MHz (RP506Lxx1K/L/M). Softstart time is Typ. 150 µs, and by connecting an external capacitor to the TSS pin, soft-start time is adjustable.
Power good (PG) function monitors the VOUT pin voltage or the feedback pin voltage (VFB), and switches the
PG pin to low if any abnormal condition is detected.
Protection circuits included in the RP506L are over current protection circuit, latch type protection circuit and
thermal shutdown circuit. Over current protection circuit supervises the inductor peak current in each switching
cycle, and if the current exceeds the LX current limit (ILXLIM), it turns off Pch Tr. Latch type protection circuit
latches the built-in driver to the OFF state and stops the operation of the step-down DC/DC converter if the
over current status continues or VOUT continues being the half of the setting voltage for equal or longer than
protection delay time (tprot). Thermal shutdown circuit detects overheating of the converter if the output pin is
shorted to the ground pin (GND) etc. and stops the converter operation to protect it from damage if the junction
temperature exceeds the specified temperature.
The RP506L is available in DFN3030-12 which achieves high-density mounting on boards.

This is an approximate value. The output current is dependent on conditions and external components.

THEORY OF OPERATION
Soft-start Time Adjustment Function
Soft-start time (tstart) of the RP506L is adjustable by connecting a soft-start time adjustment capacitor (CSS)
between the TSS pin and GND. tstart can be set from Typ. 0.15 ms. As the figure below shows, if 0.1 µF CSS
is connected, tstart will be 30 ms. The TSS pin must be open if the soft-start time function is not used. tstart is
set to 0.15 ms (Typ.) when the TSS pin is open.

Power Good Function
The RP506L contains a power good function using Nch open drain. If any abnormal condition is detected, the
power good function turns Nch transistor on and switches the PG pin to low. If the cause of the abnormal
condition is removed, the power good function turns Nch transistor off and switches the PG pin back to high.
After the recovery from abnormal condition, it takes typically 0.05 ms for the IC to turns Nch transistor off. The
followings are the abnormal conditions that the power good function can detect.

Sequential Start-up Using Soft-start Time Adjustment and Power Good Functions
Sequential startup circuits can be built by using soft-start time adjustment and power good functions of the
RP506L. The figure below is an example of sequential startup circuits using DC/DC1 and DC/DC2.
The DC/DC1 starts up first followed by the DC/DC2: the output of DC/DC1 reaches 1.44 V (VSET x 0.8), the PG
pin of DC/DC1 sends a high signal to the CE pin of DC/DC2, and then the DC/DC2 starts soft-start.
DC/DC1 (RP506L001N/M): VIN = 5.0 V, VOUT = 1.8 V, tstart = 30 ms, CSS = 0.1 µF
DC/DC2 (RP506L001N/M): VIN = 5.0 V, VOUT = 1.2 V, tstart = 30 ms, CSS = 0.1 µF

Operation of Step-down DC/DC Converter and Output Current
The step-down DC/DC converter charges energy in the inductor when LX Tr. turns “ON”, and discharges the
energy from the inductor when LX Tr. turns “OFF” and controls with less energy loss, so that a lower output
voltage (VOUT) than the input voltage (VIN) can be obtained. The operation of the step-down DC/DC converter
is explained in the following figures.

Basic Circuit
Step1.
Step2.
Step3.
Inductor Current (IL) flowing through Inductor (L)
Pch Tr. turns “ON” and IL (i1) flows, L is charged with energy. At this moment, i1 increases from the
minimum inductor current (ILmin), which is 0 A, and reaches the maximum inductor current (ILmax)
in proportion to the on-time period (ton) of Pch Tr.
When Pch Tr. turns “OFF”, L tries to maintain IL at ILmax, so L turns Nch Tr. “ON” and IL (i2) flows
into L.
i2 decreases gradually and reaches ILmin after the open-time period (topen) of Nch Tr., and then Nch
Tr. turns “OFF”. This is called discontinuous current mode.
As the output current (IOUT) increases, the off-time period (toff) of Pch Tr. runs out before IL reaches
ILmin. The next cycle starts, and Pch Tr. turns “ON” and Nch Tr. turns “OFF”, which means IL starts
increasing from ILmin. This is called continuous current mode.
In the case of PWM mode, VOUT is maintained by controlling ton. During PWM mode, the oscillator frequency
(fosc) is being maintained constant.
When the step-down DC/DC operation is constant, ILmin and ILmax during ton of Pch Tr. would be same as
during toff of Pch Tr. The current differential between ILmax and ILmin is described as ∆I.
∆I = ILmax − ILmin = VOUT × topen / L = (VIN − VOUT) × ton / L ············································· Equation 1
However,
T = 1 / fosc = ton + toff
duty (%) = ton / T × 100 = ton × fosc × 100
topen ≤ toff
In Equation 1, “VOUT × topen / L” shows the amount of current change in " OFF " state. Also, “(VIN − VOUT) × ton
/ L” shows the amount of current change at "ON" state.

No. EC-296-210909
Discontinuous Mode and Continuous Mode
As illustrated in Figure A, when IOUT is relatively small, topen < toff. In this case, the energy charged into L
during ton will be completely discharged during toff, as a result, ILmin = 0. This is called discontinuous mode.
When IOUT is gradually increased, eventually topen = toff and when IOUT is increased further, eventually ILmin
> 0, as illustrated in Figure B. This is called continuous mode.

When ton < tonc, it is discontinuous mode, and when ton = tonc, it is continuous mode.

Forced PWM Mode
By setting the MODE pin to “H”, the IC switches the frequency at the fixed rate to reduce noise even when
the output load is light. Therefore, when IOUT is ∆IL/2 or less, ILmin becomes less than 0. That is, the
accumulated electricity in CL is discharged through the IC side while IL is increasing from ILmin to 0 during
ton, and also while IL is decreasing from 0 to ILmin during toff.

VFM Mode
By setting the MODE pin to “L”, in low output current, the IC automatically switches into VFM mode in order
to achieve high efficiency. In VFM mode, ton is forced to end when the inductor current reaches the pre-set
ILmax. In the VFM mode, ILmax is typically set to 400 mA for the RP506Lxx1G/H//N, and 550 mA for the
RP506Lxx1K/L/M. When ton reaches 1.5 times of T = 1 / fosc, ton will be forced to end even if the inductor
current is not reached ILmax.

Output Current and Selection of External Components
The following equations explain the relationship between output current and peripheral components that are
listed in Table1. Recommended External Components in Typical Application.
Ripple Current P-P value is described as IRP, ON resistance of Pch Tr. is described as RONP, ON resistance of
Nch Tr. is described as RONN, and DC resistor of the inductor is described as RL.
First, when Pch Tr. is “ON”, the following equation is satisfied.
VIN = VOUT + (RONP + RL) × IOUT + L × IRP / ton ································································· Equation 3
Second, when Pch Tr. is "OFF" (Nch Tr. is "ON"), the following equation is satisfied.
L × IRP / toff = RONN × IOUT + VOUT + RL × IOUT ·································································· Equation 4
Put Equation 4 into Equation 3 to solve ON duty of Pch Tr. (DON = ton / (toff + ton)):
DON = (VOUT + RONN × IOUT + RL × IOUT) / (VIN + RONN × IOUT − RONP × IOUT) ······························· Equation 5
Ripple Current is described as follows:
IRP = (VIN − VOUT − RONP × IOUT − RL × IOUT) × DON / fosc / L ················································ Equation 6
Peak current that flows through L, and LX Tr. is described as follows:
ILXmax = IOUT + IRP / 2 ······························································································· Equation 7
Notes: Please consider ILxmax when setting conditions of input and output, as well as selecting the external
components. The above calculation formulas are based on the ideal operation of the ICs in continuous mode.

Starting-up with CE Pin
The IC starts to operate when the CE pin voltage (VCE) exceeds the threshold voltage. The threshold voltage
is preset between CE “H” input voltage (VCEH) and CE “L” input voltage (VCEL).
After the start-of the start-up of the IC, soft-start circuit starts to operate. Then, after a certain period of time,
the reference voltage (VREF) in the IC gradually increases up to the specified value.

(2) Under Voltage Lockout (UVLO) Circuit
If VIN becomes lower than VSET, the step-down DC/DC converter stops the switching operation and ON duty
becomes 100%, and then VOUT gradually drops according to VIN.
If the VIN drops more and becomes lower than the UVLO detector threshold (VUVLO1), the UVLO circuit starts
to operate, VREF stops, and Pch and Nch built-in switch transistors turn “OFF”. As a result, VOUT drops according
to the COUT capacitance value and the load.
To restart the operation, VIN needs to be higher than VUVLO2. The timing chart below shows the voltage shifts
of VREF, VLX and VOUT when VIN value is varied.

(3) Over Current Protection Circuit, Latch Type Protection Circuit
Over current protection circuit supervises the inductor peak current (the peak current flowing through Pch Tr.)
in each switching cycle, and if the current exceeds the LX current limit (ILXLIM), it turns off Pch Tr. ILXLIM of the
RP506L is set to Typ.2800 mA.
Latch type protection circuit latches the built-in driver to the OFF state and stops the operation of the stepdown DC/DC converter if the over current status continues or VOUT continues being the half of the setting
voltage for equal or longer than protection delay time (tprot). To release the latch type protection circuit, restart
the IC by inputting "L" signal to the CE pin, or restart the IC with power-on or make the supply voltage lower
than VUVLO1.
Notes: ILXLIM and tprot could be easily affected by self-heating or ambient environment. If the VIN drops
dramatically or becomes unstable due to short-circuit, protection operation and tprot could be affected.

The timing chart below shows the voltage shift of VCE, VLX and VOUT when the IC status is changed by the
following orders: VIN rising → stable operation → high load → CE reset → stable operation → VIN falling → VIN
recovering (UVLO reset) → stable operation.
(1)(2) If the large current flows through the circuit or the IC goes into low VOUT condition due to short-circuit or
other reasons, the latch type protection circuit latches the built-in driver to “OFF” state after tprot. Then,
VLX becomes "L" and VOUT turns “OFF”.
(3) The latch type protection circuit is released by CE reset, which puts the IC into "L" once with the CE pin
and back into "H".
(4) The latch type protection circuit is released by UVLO reset, which makes VIN lower than VUVLO1.

TECHNICAL NOTES
The performance of a power source circuit using this device is highly dependent on a peripheral circuit. A
peripheral component or the device mounted on PCB should not exceed a rated voltage, a rated current or a
rated power. When designing a peripheral circuit, please be fully aware of the following points.
AGND and PGND must be wired to the GND plane when mounting on boards.
AVIN and PVIN must be wired to the VIN plane when mounting on boards.
Ensure the A/PVIN and A/PGND lines are sufficiently robust. A large switching current flows through the
A/ PGND line, the VDD line, the VOUT line, an inductor, and LX. If their impedance is too high, noise pickup
or unstable operation may result. Set the external components as close as possible to the IC and minimize
the wiring between the components and the IC. Especially, place a capacitor (CIN) as close as possible
to the PVIN pin and PGND. For the RP506Lxx1G/H/K/L, separate the wiring between the VOUT pin and an
inductor (L1) from the wiring between L1 and Load. Likewise, for the RP506L001N/M, separate the wiring
between a resistor for setting output voltage (R1) and an inductor (L2) from the wiring between L2 and
Load.
Choose a low ESR ceramic capacitor. The ceramic capacitance of CIN should be more than or equal to
10 µF. For a ceramic capacitor (COUT), it is recommended that three paralleled 10 µF ceramic capacitors
or two paralleled 22 µF ceramic capacitors be used.
When VSET ≤ 3.3 V, a 2.2 μH inductor is recommended for RP506Lxx1G/H//N/K/L/M. When VSET ≤ 2.3 V,
a 1.5 μH inductor can be used for RP506Lxx1G/H//N. When VSET ≤ 1.5 V, a 1 μH inductor can be used
for RP506Lxx1G/H//N. When VSET > 3.3 V, a 4.7 μH inductor is recommended for RP506L001N/M. The
phase compensation of this IC is designed according to the COUT and L values. Choose an inductor that
has small DC resistance, has enough allowable current and is hard to cause magnetic saturation. If the
inductance value of an inductor is extremely small, the peak current of LX may increase along with the
load current. As a result, over current protection circuit may start to operate when the peak current of LX
reaches to “LX limit current”.

Overcurrent protection circuit and latch type protection circuit may be affected by self-heating or power
dissipation environment.
The output voltage (VOUT) is adjustable by changing the resistance values of resistors (R1, R2) as follows.
VOUT = VFB × (R1 + R2) / R2
Recommended VOUT range for RP506L001M: 0.6 V ≤ VSET ≤ 4.0 V,
Recommended VOUT range for RP506L001N: 0.8 V ≤ VSET ≤ 4.0 V
If R1 and R2 are too large, the impedances of VFB also become large, as a result, the IC could be easily
affected by noise. For this reason, R2 should be 220 kΩ or less. If the operation becomes unstable due
to the high impedances, the impedances should be decreased.
C1 can be calculated by the following equations. Please use the value close to the calculation result.
If the output voltage is lower than or equal to 3.3 V:
C1 = 4.84 × 10-6 / R2 [F]
If the output voltage exceeds 3.3 V:
C1 = 1.50 × 10-6 / R2 [F]
The recommended resistance values for R1 and C1 when R2 = 220 kΩ or 100 kΩ are as follows.

Soft-start Time (tstart) is adjustable by connecting a capacitor (CSS) between the TSS pin and GND. The
capacitance value for CSS that is suitable for tstart can be calculated by the following equation.
CSS (nF) = 3.5 × tstart (ms)
The TSS pin must be open if Soft-start time function is not used. Soft-start time is set to typically 150 µs
when the TSS pin is open.
When using the power good function, the resistance value of a resistor (RPG) should be between 10 kΩ to
100 kΩ. The PG pin must be open or connected to GND if the power good function is not used.
