TMI7003C
GENERAL DESCRIPTION
Feature Description
TMI7003C is a highly efficient and integrated Power Management IC for Systems-on-a-Chip (SoCs), ASICs,
and processors. The device incorporates 3 high-efficiency synchronous buck regulators.
Each of the buck regulators is specially designed for high-efficiency operation throughout the load range.
With 1.5MHz typical switching frequency, the external L-C filter can be small and still provide very low output
voltage ripple. The bucks are internally compensated to be stable with the recommended external inductors
and capacitors as detailed in the application diagram. Synchronous rectification yields high efficiency for low
voltage and high output currents.
Additional features include soft-start, under-voltage lockout, bypass, and current and thermal overload
protection.
3 channel BUCKs are nearly identical in performance and mode of operation. They can operate in automatic
mode (PWM/PFM). At very light loads, BUCKs enter PFM mode and operate with reduced switching
frequency and supply current to maintain high efficiency.
Soft-Start
Each of BUCKs has an internal soft-start circuit that limits the in-rush current during startup. This allows the
converters to gradually reach the steady-state operating point, thus reducing startup stresses and surges.
During startup, the switch current limit is increased in steps. The startup time depends on the output
capacitor size, load current and output voltage. The typical soft-start time is 1ms.
Current Limiting
A current limit feature protects the device and any external components during overload conditions. In
PWM mode the current limiting is implemented by using an internal comparator that trips at current levels
according to the buck capability. If the output is shorted to ground the device enters a timed current limit
mode where the NFET is turned on for a longer duration until the inductor current falls below a low
threshold, ensuring inductor current has more time to decay, thereby preventing runaway.
Uder-Voltage Lock Out (UVLO)
The VIN voltage is monitored for a supply under voltage condition, for which the operation of the device
cannot be guaranteed. The part will automatically disable PMIC. To prevent unstable operation, the UVLO
has a hysteresis window. An under-voltage lockout (UVLO) will disable BUCKs outputs, Once the supply
voltage is above the UVLO hysteresis, the device will initiate a power-up sequence and then enter the active
state.
Input Over Voltage Protection (IOVP)
The VIN voltage is monitored for a supply over voltage condition, for which the operation of the device
cannot be guaranteed. The purpose of IOVP is to protect the part and all other components connected to
the PMIC outputs from any damage and malfunction. Once VIN rises over about 6.0V, BUCKs will be disabled
automatically. To prevent unstable operation, the IOVP has a hysteresis window. An input over voltage

protection (IOVP) will force the device into the reset state, Once the supply voltage goes below the OVLO
lower threshold, the device will initiate a power-up sequence and then enter the active state.
Thermal Shutdown (OTP)
The temperature of the silicon die is monitored for an over-temperature condition, for which the operation
of the device cannot be guaranteed. The part will automatically be disabled if the temperature is too high.
The thermal shutdown (OTP) will force the device into the reset state. In reset, all circuitry is disabled. To
prevent unstable operation, the OTP has a hysteresis window of about 20°C. Once the temperature has
decreased below the OTP hysteresis, the device will initiate a power-up sequence and then enter the active
state. In the active state, the part will start up as if for the first time.

DETAILED DESIGN PROCEDURE
External Components Selection
TMI7003C require an input capacitor, an output capacitor and an inductor. These components are critical
to the performance of the device. TMI7003C are internally compensated and do not require external
components to achieve stable operation. The output voltage can be programmed by resistor divider.

Output Inductors and Capacitors Selection
There are several design considerations related to the selection of output inductors and capacitors:
• Load transient response
• Stability
• Efficiency
• Output ripple voltage
• Over current ruggedness
The device has been optimized for use with nominal LC values as shown in the Application Diagram.
BUCK Power Supply Recommendations
TMI7003C are designed to operate from input voltage supply range between 2.5 V and 5.5 V. This input
supply must be well regulated. If the input supply is located more than a few inches, additional bulk
capacitance may be required in addition to the ceramic bypass capacitors. A ceramic capacitor with an
effective value of 4.7μF is a typical choice.
VIN must be connected to input capacitors as close as possible.
BUCK Inductor Selection
The recommended inductor values are shown in the Application Diagram. It is important to guarantee the
inductor core does not saturate during any foreseeable operational situation. The inductor should be rated
to handle the peak load current plus the ripple current: Care should be taken when reviewing the different
saturation current ratings that are specified by different manufacturers. Saturation current ratings are
typically specified at 25°C, so ratings at maximum ambient temperature of the application should be
requested from the manufacturer.

Recommended Method for BUCK Inductor Selection
The best way to guarantee the inductor does not saturate is to choose an inductor that has saturation
current rating greater than the maximum device current limit, as specified in the Electrical Characteristics.
In this case the device will prevent inductor saturation by going into current limit before the saturation level
is reached.
Alternate Method for BUCK Inductor Selection
If the recommended approach cannot be used care must be taken to guarantee that the saturation current
is greater than the peak inductor current:

Output and Input Capacitors Characteristics
Special attention should be paid when selecting these components. The DC bias of these capacitors can
result in a capacitance value that falls below the minimum value given in the recommended capacitor
specifications table.
The ceramic capacitor’s actual capacitance can vary with temperature. The capacitor type X7R, which
operates over a temperature range of −55°C to +125°C, will only vary the capacitance to within ±15%. The
capacitor type X5R has a similar tolerance over a reduced temperature range of −55°C to +85°C. Many large
value ceramic capacitors, larger than 1uF are manufactured with Z5U or Y5V temperature characteristics.
Their capacitance can drop by more than 50% as the temperature varies from 25°C to 85°C, therefore X5R
or X7R is recommended over Z5U and Y5V in applications where the ambient temperature will change
significantly above or below 25°C.
BUCK Output Capacitor Selection
The output capacitor of a switching converter absorbs the AC ripple current from the inductor and provides
the initial response to a load transient. The ripple voltage at the output of the converter is the product of
the ripple current flowing through the output capacitor and the impedance of the capacitor. The impedance
of the capacitor can be dominated by capacitive, resistive, or inductive elements within the capacitor,
depending on the frequency of the ripple current. Ceramic capacitors have very low ESR and remain
capacitive up to high frequencies. Their inductive component can be usually neglected at the frequency
ranges the switcher operates.
The output-filter capacitor smooths out the current flow from the inductor to the load and helps maintain
a steady output voltage during transient load changes. It also reduces output voltage ripple. These
capacitors must be selected with sufficient capacitance and low enough ESR to perform these functions.
Note that the output voltage ripple increases with the inductor current ripple and the Equivalent Series
Resistance of the output capacitor (ESRCOUT), also note that the actual value of the capacitor’s ESRCOUT is
frequency and temperature dependent, as specified by its manufacturer. The ESR should be calculated at
the applicable switching frequency and ambient temperature.

The device is designed to be used with ceramic capacitors on the outputs of the buck regulators. The
recommended dielectric type of these capacitors is X5R, X7R, or of comparable material to maintain proper
tolerances over voltage and temperature. The recommended effective value for the output capacitors is
10µF with an ESR of 2mΩ or less. The output capacitors need to be mounted as close as possible to the
output/ground terminals of the device.
BUCK Input Capacitor Selection
Input capacitor should be located as close as possible to their corresponding VIN and GND terminals,
tantalum capacitor can also be located in the proximity of the device.
The input capacitor supplies the AC switching current drawn from the switching action of the internal power
MOSFETs. The input current of a buck converter is discontinuous, so the ripple current supplied by the input
capacitor is large. The input capacitor must be rated to handle both the RMS current and the dissipated
power. The input capacitor must be rated to handle this current:
√VOUT *(VIN -VOUT )
VIN
The power dissipated in the input capacitor is given by:
VRMS_CIN =IOUT
PD_CIN =I2RMS_CIN *RESR_CIN
The device is designed to be used with ceramic capacitors on the inputs of the buck regulators. The
recommended dielectric type of these capacitors is X5R, X7R, or of comparable material to maintain proper
tolerances over voltage and temperature. The minimum recommended effective value for the input
capacitor is larger than 4.7µF with an ESR of 10mΩ or less. The input capacitors need to be mounted as close
as possible to the power/ground input terminals of the device.
The input power source supplies the average current continuously. During the high side MOSFET switch ontime, however, the demanded di/dt is higher than can be typically supplied by the input power source. This
delta is supplied by the input capacitor.
A simplified “worst case” assumption is that all of the high side MOSFET current is supplied by the input
capacitor. This will result in conservative estimates of input ripple voltage and capacitor RMS current.
Input ripple voltage is estimated as follows:
VPPIN =
IOUT *D
+I *ESRCIN
CIN *FS OUT
where
• VPPIN: Estimated peak-to-peak input ripple voltage
• IOUT: Output current
• CIN: Input capacitor value

Layout Guidelines
PC board layout is an important part of DC-DC converter design. Poor board layout can disrupt the
performance of a DC-DC converter and surrounding circuitry by contributing to EMI, ground bounce, and
resistive voltage loss in the traces. These can send erroneous signals to the DC-DC converter resulting in
poor regulation or instability. Good layout can be implemented by following a few simple design rules.
1. Minimize area of switched current loops. In a buck regulator there are two loops where currents are
switched rapidly. The first loop starts from the CIN input capacitor, to the regulator VIN terminal, to the
regulator SW terminal, to the inductor then out to the output capacitor COUT and load. The second loop
starts from the output capacitor ground, to the regulator GND terminals, to the inductor and then out to
COUT and the load. To minimize both loop areas the input capacitor should be placed as close as possible
to the VIN terminal. Grounding for both the input and output capacitors should consist of a small localized
top side plane that connects to GND. The inductor should be placed as close as possible to the SW pin and
output capacitor.
2. Minimize the copper area of the switch node. The SW terminals should be directly connected with a trace
that runs on top side directly to the inductor. To minimize IR losses this trace should be as short as possible
and with a sufficient width. However, a trace that is wider than 100 mils will increase the copper area and
cause too much capacitive loading on the SW terminal. The inductors should be placed as close as possible
to the SW terminals to further minimize the copper area of the switch node.
3. Have a single point ground for all device analog grounds. The ground connections for the feedback
components should be connected together then routed to the GND of the device. This prevents any
switched or load currents from flowing in the analog ground plane. If not properly handled, poor grounding
can result in degraded load regulation or erratic switching behavior.
4. Minimize trace length to the FB terminal. The feedback trace should be routed away from the SW pin and
inductor to avoid contaminating the feedback signal with switch noise.
5. Make input and output bus connections as wide as possible. This reduces any voltage drops on the input
or output of the converter and can improve efficiency. If voltage accuracy at the load is important make sure
feedback voltage sense is made at the load. Doing so will correct for voltage drops at the load and provide
the best output accuracy.
