The MIC33050 also has a very low typical quiescent
current of 20 µA and can achieve over 85% efficiency
even at 1 mA.
In contrast to traditional light load schemes, the
HyperLight Load® architecture does not trade off
control speed to obtain low standby currents and in
doing so, the device only needs a small output
capacitor to absorb the load transient as the powered
device goes from light load to full load.
At higher loads, the MIC33050 provides a nearly
constant switching frequency of greater than 4 MHz
while providing peak efficiencies greater than 93%.
The MIC33050 is available in fixed and adjustable
output voltages and comes in a 12-pin 3 mm x 3 mm
HDFN with a operating junction temperature range of
–40°C to +125°C.

Note 1:
The maximum allowable power dissipation is a function of ambient temperature, the maximum allowable
junction temperature and the thermal resistance from junction to air (i.e., TA, TJ, JA). Exceeding the
maximum allowable power dissipation will cause the device operating junction temperature to exceed the
maximum +125°C rating. Sustained junction temperatures above +125°C can impact the device reliability.

FUNCTIONAL DESCRIPTION
4.1
VIN
VIN provides power to the MOSFETs for the switch
mode regulator section and to the analog supply
circuitry. Due to the high switching speeds, it is
recommended that a 2.2 µF or greater capacitor be
placed close to VIN and the power ground (PGND) pin
for bypassing.
4.2
EN
4.7
The feedback pin is provided for the adjustable output
version. An external resistor divider network is
connected from the output and is compared to the
internal 400 mV internal reference voltage within the
control loop.
The output voltage, of the circuit in Figure 4-1, may be
calculated via the equation below:
EQUATION 4-1:
The enable pin, EN, controls the on and off state of the
device. A high logic on the enable pin activates the
regulator while a low logic deactivates it. MIC33050
features built-in soft-start circuitry that reduces in-rush
current and prevents the output voltage from
overshooting at start-up. Do not leave floating.
4.3
FB
V OUT = 0.4V 1 + R1
-------
R2
SW
The pins at the switch node, SW, are connected directly
to the internal inductor. Due to the high-speed
switching on this pin, the switch node should be routed
away from sensitive nodes such as the CFF and FB
pins.
4.4
SNS
The sense pin, SNS, is needed to sense the output
voltage at the output filter capacitor. In order for the
control loop to monitor the output voltage accurately it
is good practice to sense the output voltage at the
positive side of the output filter capacitor where voltage
ripple is smallest.
4.6
R2
OUT
The OUT pin is for the output voltage following the
internal inductor of the device. Connect an output filter
capacitor equal to 2.2 µF or greater to this pin.
4.5
R1
CFF
The CFF pin is connected to the SNS pin of MIC33050
with a feed-forward capacitor of 560 pF. The CFF pin
itself is compared with the internal reference voltage
(VREF) of the device and provides the control path to
control the output. VREF is equal to 400 mV. The CFF
pin is sensitive to noise and should be place away from
the SW pin.

Application Schematic.
4.8
PGND
Power ground (PGND) is the ground path for high
current. The current loop for the power ground should
be as small as possible and separate from the analog
ground (AGND) loop.
4.9
AGND
Signal ground (AGND) is the ground path for the
biasing and control circuitry. The current loop for the
signal ground should be separate from the PGND loop.

APPLICATIONS INFORMATION
5.1
Input Capacitor
A minimum of 2.2 µF ceramic capacitor should be
placed close to the VIN pin and PGND pin for
bypassing. X5R or X7R dielectrics are recommended
for the input capacitor. Y5V dielectrics, aside from
losing most of their capacitance over temperature, they
also become resistive at high frequencies. This
reduces their ability to filter out high frequency noise.
5.2
Output Capacitor
The MIC33050 was designed for use with a 2.2 µF or
greater ceramic output capacitor. A low equivalent
series resistance (ESR) ceramic output capacitor either
X7R or X5R is recommended. Y5V and Z5U dielectric
capacitors, aside from the undesirable effect of their
wide variation in capacitance over temperature,
become resistive at high frequencies.
5.3
Compensation
The MIC33050 is designed to be stable with an internal
inductor with a minimum of 2.2 µF ceramic (X5R)
output capacitor.
5.4
Efficiency Considerations
Efficiency is defined as the amount of useful output
power, divided by the amount of power supplied.
EQUATION 5-1:
V OUT I OUT
= -------------------------------- 100
V IN I IN
Maintaining high efficiency serves two purposes. It
reduces power dissipation in the power supply,
reducing the need for heat sinks and thermal design
considerations and it reduces consumption of current
for battery powered applications. Reduced current
draw from a battery increases the devices operating
time which is critical in hand held devices.
There are two types of losses in switching converters;
DC losses and switching losses. DC losses are simply
the power dissipation of I2R. Power is dissipated in the
high-side switch during the on cycle. Power loss is
equal to the high-side MOSFET RDS(ON) multiplied by
the switch current squared. During the off cycle, the
low-side N-channel MOSFET conducts, also
dissipating power. Device operating current also
reduces efficiency. The product of the quiescent
(operating) current and the supply voltage represents
another DC loss. The current required driving the gates
on and off at a constant 4 MHz frequency and the
switching transitions make up the switching losses.

FIGURE 5-1:
Efficiency under Load.
Figure 5-1 shows an efficiency curve. From 1 µA to
100 mA, efficiency losses are dominated by quiescent
current losses, gate drive and transition losses. By
using the HyperLight Load® mode, the MIC33050 is
able to maintain high efficiency at low output currents.
Over 100 mA, efficiency loss is dominated by MOSFET
RDS(ON) and inductor losses. Higher input supply
voltages will increase the gate to source threshold on
the internal MOSFETs, thereby reducing the internal
RDS(ON). This improves efficiency by reducing DC
losses in the device. All but the inductor losses are
inherent to the device. In which case, inductor selection
becomes increasingly critical in efficiency calculations.
As the inductors are reduced in size, the DC resistance
(DCR) can become quite significant.
The DCR losses can be calculated by using
Equation 5-2:
EQUATION 5-2:
2
P D L I OUT DCR
From that, the loss in efficiency due to inductor
resistance can be calculated by using Equation 5-3:

MIC33050
EQUATION 5-3:
V OUT I OUT
EfficiencyLoss = 1 – ---------------------------------------------------- 100
V OUT I OUT + P D L
Efficiency loss due to DCR is minimal at light loads and
gains significance as the load is increased. Inductor
selection becomes a trade-off between efficiency and
size in this case.
5.5
HyperLight Load® Mode
The MIC33050 uses a minimum on and off time
proprietary control loop. When the output voltage falls
below the regulation threshold, the error comparator
begins a switching cycle that turns the PMOS on and
keeps it on for the duration of the minimum on-time.
When the output voltage is over the regulation
threshold, the error comparator turns the PMOS off for
a minimum off-time. The NMOS acts as an ideal
rectifier that conducts when the PMOS is off. Using a
NMOS switch instead of a diode allows for lower
voltage drop across the switching device when it is on.
The asynchronous switching combination between the
PMOS and the NMOS allows the control loop to work
in discontinuous mode for light load operations. In
discontinuous mode, MIC33050 works in pulse
frequency modulation (PFM) to regulate the output. As
the output current increases, the switching frequency
increases. This improves the efficiency of the
MIC33050 during light load currents. As the load
current increases, the MIC33050 goes into continuous
conduction mode (CCM) at a constant frequency of
4 MHz. The equation to calculate the load when the
MIC33050 goes into continuous conduction mode may
be approximated by the following Equation 5-4:

V IN – V OUT D
