The NCP1575 is a low voltage buck controller. It provides the

control for a dc-dc power solution producing an output voltage as low

as 0.980 V over a wide current range. It contains all required circuitry

for a synchronous NFET buck regulator using the V

method to achieve the fastest possible transient response and best

overall regulation. The NCP1575 operates at a default switching

frequency of 200 kHz, but switching frequency is user-programmable

with an additional resistor between R

and ground. This device

provides undervoltage lockout protection, Soft Start, and built-in

adaptive nonoverlap and is assembled in an SO-8 package.

The NCP1575-based solution requires a bias supply of 12 V, and it

can convert from a bulk power supply ranging from 2 V to 12 V.

Conversion from bulk supplies greater than 7 V is best accomplished

by using an external doubler circuit to raise the enhancement voltage

for the external NFET switches.
