Pin Description

Pin Number Pin Name Function

1 COMP

Compensation Point. COMP is used to compensate the regulation control

loop. Connect R and C from COMP and GND to compensate the regulation

control loop

2 GND

Ground. The exposed pad is soldered to PCB and connected to GND plant

for good power dissipation

3 EN

Enable Input. EN is an input when the regulator on or off. When left

unconnected, EN pin is pulled to VDD by the internal pull up resistor

4 VDD

Power input V

provides the input power to the regulator. Connecting a

ceramic bypass capacitor between VDD and GND to eliminate input

noise and ripple voltage

Switch Output. SW is the switching point which supplies voltage and

current to output

7 F_ADJ

Oscillator Resistor Input. Connecting a resistor to ground from this pin sets

the switching frequency

8 FB

Feedback Input. Receives the feedback voltage from a resistive divider

connected across the output. The feedback reference voltage is 0.8V
