Type Description
1
OUT
Regulator output
2
SYNCH
Master/Slave Synchronization. When it is left floating, a signal with a phase shift of half a period respect to the power turn
on is present at the pin. When connected to an external signal at a frequency higher than the internal one, then the
device is synchronized by the external signal, with zero phase shift.
Connecting together the SYNC pin of two devices, the one with higher frequency works as master and the other one as
slave; so the two power turn on have a phase shift of half a period.
3
INH
A logical signal (active high) disable the device. With INH higher than 1.9V the device is OFF and with INH lower than
0.6V the device is ON.
4
COMP
Error Amplifier output to be used for loop frequency compensation
5
FB
Feedback input. Connecting the output voltage directly to this pin the output voltage is regulated at 0.6V. To have higher
regulated voltages an external resistor divider is required from Vout to FB pin.
6
F
SW
The switching frequency can be increased connecting an external resistor from FSW pin and ground. If this pin is left
floating the deice works at its free-running frequency of 250KHz.

GND
Ground
