Pin Functions

PIN I/O DESCRIPTION
NO. NAME
1 EN IN Device enable logic input. Do not leave floating.
Logic HIGH enables the device, logic LOW disables the device and turns it into shutdown.
2, 3 GND PWR Power and signal ground.
4 FB IN Feedback terminal for the internal control loop.
Connect this terminal to the external feedback divider to program the output voltage.
5 VOS IN Output voltage sense terminal for the internal control loop. Must be connected to output.
6 PG OUT Power Good open drain output.
This terminal is pulled to low if the output voltage is below regulation limits. This terminal can be left floating if not used.
7 SW PWR Switch terminal connected to the internal MOSFET switches and inductor terminal.
Connect the inductor of the output filter here.
8 VIN PWR Power supply voltage input.
Exposed Thermal Pad — Must be connected to GND. Must be soldered to achieve appropriate power dissipation and mechanical reliability.
