DESCRIPTION

The device is a pwm controller for high performance

dc-dc conversion from 3.3V, 5V and 12V buses.

The output voltage is adjustable down to 0.9V; higher

voltages can be obtained with an external voltage di-

vider.

High peak current gate drivers provide for fast switch-

ing to the external power section, and the

output

current can be in excess of 20A.

The device assures protections against load overcur-

rent and overvoltage. An internal crowbar is also pro-

vided turning on the low side mosfet as long as the

over-voltage is detected. In case of over-current de-

tection, the soft start capacitor is discharged and the

system works in HICCUP mode.
