Type
Description
1
VINA
Unregulated DC input voltage
2EN
Enable input. With EN higher than 1.5 V the device is ON and with EN
lower than 0.5 V the device is OFF.
3FB
Feedback input. Connecting the output voltage directly to this pin the
output voltage is regulated at 0.8 V. To have higher regulated voltages an
external resistor divider is required from VOUT to the FB pin.
4
AGND
Ground
5PG
Open drain Power Good (POR) pin. It is released (open drain) when the
output voltage is higher than 0.92 * VOUT with a delay of 170 s. If the
output voltage is below 0.92 * VOUT, the POR pin goes to low impedance
immediately. If not used, it can be left floating or to GND.
6
VINSW
Power input voltage
7
SW
Regulator output switching pin
8
PGND
Power ground
ePAD
(VFDFPN package only) exposed pad connected to ground assuring
electrical contact and heat conduction.
