Pin Functions

PIN TYPE(1) DESCRIPTION
NAME NO.
AGND 3 I Analog GND supply pin for the control circuit.
AVIN 7 I Analog VIN power supply for the control circuit. Need to be connected to PVIN and input capacitor.
EN 5 I This is the enable pin of the device. Pulling this pin to low forces the device into shutdown mode. Pulling this pin to high enables the device. This pin must be terminated
Exposed Thermal Pad — — For good thermal performance, this pad must be soldered to the land pattern on the PCB. This pad should be used as device GND.
FB 4 I Feedback pin for the internal regulation loop. Connect the external resistor divider to this pin. In case of fixed output voltage option, connect this pin directly to the output capacitor
MODE 6 I MODE pin = High forces the device to operate in fixed frequency PWM mode. MODE pin = Low enables the power save mode with automatic transition from PFM mode to fixed frequency PWM mode. This pin must be terminated.
PGND 1 P GND supply pin for the output stage.
PVIN 8 P VIN power supply pin for the output stage.
SW 2 O This is the switch pin and is connected to the internal MOSFET switches. Connect the external inductor between this terminal and the output capacitor.
(1) I = Input, O = Output, P = Power
