NCP1575 Low Voltage Synchronous Buck Controller with Adjustable Switching Frequency
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 V2t 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 ...
