POWER MANAGEMENT

12

DH

Gate drive output for the high side MOSFET switch.

13

BST

Boost capacitor connection for the high side gate drive.

14

NC

Not connected.

15

EN/PSV

Enable/Power Save input. Pull down to VSSA to shut down VOUT and discharge it through

22

Ω (nom.). Pull up to enable VOUT and activate PSAVE mode. Float to enable VOUT ac-

tivate continuous conduction mode (CCM). If floated, bypass to VSSA with a 10nF ceramic

capacitor.

16

TON

This pin is used to sense VBAT through a pullup resistor, RTON, and to set the top MOSFET

on-time. Bypass this pin with a 1nF ceramic capacitor to VSSA.

Thermal

Pad

Pad for heatsinking purposes. Connect to ground plane using multiple vias.

Not connected internally.
