Pin Functions

NAME SOT563-6 I/O/PWR DESCRIPTION
PIN NUMBER
FB 1 I Feedback pin for the internal control loop. Connect this pin to an external feedback divider.
GND 2 PWR Ground pin.
VIN 3 PWR Power supply voltage input.
SW 4 PWR Switch pin connected to the internal FET switches and inductor terminal. Connect the inductor of the output filter to this pin.
EN 5 I Device enable logic input. Logic high enables the device, logic low disables the device and turns it into shutdown. Do not leave floating.
PG 6 O Power good open drain output pin for TLV62569APDRL. The pull-up resistor should not be connected to any voltage higher than 5.5V. If it's not used, leave the pin floating.
NC 6 - No connection pin for TLV62569ADRL. The pin can be connected to the output or the ground for enhancing thermal performance. Or leave it floating.
