DESCRIPTION
NAME
NO.
BOOT
1
O
A bootstrap capacitor is required between the BOOT and SW pins to supply the bias voltage for the integrated
high-side MOSFET.
COMP
12
O
The COMP pin is the error-amplifier output of the buck regulator, and the input to the output switch-current
comparator of the buck regulator. Connect frequency-compensation components to the COMP pin.
EN1
8
I
The EN1 pin is the enable and disable input for the buck regulator (high-voltage tolerant) and is internally
pulled to ground. Pull this pin up externally to enable the buck regulator.
EN2
7
I
The EN2 pin is the enable and disable input for the LDO regulator (high-voltage tolerant) and is internally
pulled to ground. Pull this pin up externally to enable the LDO regulator.
FB1
11
I
The FB1 pin is the feedback pin of the buck regulator. Connect an external resistive divider between the buck
regulator output, the FB2 pin, and the GND pin to set the desired output voltage of the buck regulator.
FB2
5
I
The FB2 pin is the feedback pin of the LDO regulator. Connect an external resistive divider between the
LDO_OUT pin, the FB2 pin, and the GND pin to set the desired output voltage of the LDO regulator.
GND
13
This pin is the ground pin.
LDO_OUT
4
O
This pin is the LDO regulator output.
nRST
6
O
The nRST pin is the active low, open drain reset output of the buck regulator. Connect this pin with an external
bias voltage through an external resistor. This pin is asserted high after the buck regulator begins regulating.
RT/CLK
9
I
Connect this pin to an external resistor to ground to program the switching frequency of the buck regulator. An
alternative option is to feed an external clock to provide a reference for the switching frequency of the buck
regulator.
SS
10
I
Connect this pin to an external capacitor to ground which sets the soft-start time of the buck regulator.
SW
14
I
The SW pin is the source node of the internal high-side MOSFET of the buck regulator.
VIN
2
The VIN pin is the input supply pin for the internal biasing and high-side MOSFET of the buck regulator.
VIN_LDO
3
The VIN_LDO pin is the input supply pin for the LDO regulator.
Exposed
PowerPAD
Electrically connect the PowerPAD to ground and solder to the ground plane of the PCB for thermal
performance.
