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 V2�
control 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 ROSC and ground. This device
provides undervoltage lockout protection, soft−start, and built−in
adaptive nonoverlap and is assembled in an SOIC−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.
