I/O DESCRIPTION
NAME NO.
VIN 8 PWR Power Supply Voltage Input.
EN 1 IN Device Enable Logic Input.
Logic HIGH enables the device, logic LOW disables the device and turns it into shutdown.
MODE 3 IN Snooze Mode Enable Logic Input.
Logic HIGH enables the Snooze Mode, logic LOW disables the Snooze Mode
GND 2 PWR Power and Signal Ground.
VOS 5 IN Output Voltage Sense Pin for the internal control loop. Must be connected to output.
SW 7 PWR Switch Pin connected to the internal MOSFET switches and inductor terminal.
Connect the inductor of the output filter here.
FB 4 IN Feedback Pin for the internal control loop.
Connect this pin to the external feedback divider for the adjustable output version. For the fixed output voltage
versions this pin must be left floating or connected to GND.
PG 6 OUT Power Good open drain output.
This pin is pulled to low if the output voltage is below regulation limits. Can be left floating if not used.
Thermal Pad Connect it to GND.
