Low Voltage Synchronous Buck Controller

The NCP1575 is a low voltage buck controller. It provides the control for dc-dc power solution producing an output voltage as low as 0.980V over a wide current range. It contains all required circuitry for a synchronous NFET buck regulator using the V2TM control method to achieve the fastest possible transient response and best overall regulation. The NCP1575 operates at a default switching frequency of 200kHz, 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 assemble in an SO-8 package.
