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-...
