Pin Functions

PIN NUMBER I/O/PWR DESCRIPTION
NAME SOT23-5 SOT23-6 SOT563-6
EN 1 1 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.
GND 2 2 2 PWR Ground pin.
SW 3 3 4 PWR Switch pin connected to the internal FET switches and inductor terminal. Connect the inductor of the output filter to this pin.
VIN 4 4 3 PWR Power supply voltage input.
PG - 5 6 O Power good open drain output pin for TLV62569P. The pull-up resistor should not be connected to any voltage higher than 5.5V. If it's not used, leave the pin floating.
FB 5 6 1 I Feedback pin for the internal control loop. Connect this pin to an external feedback divider.
NC - - 6 O No connection pin for TLV62569DRL. The pin can be connected to the output or the ground. Or leave it floating.
