Manufacturer: Description: 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 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. |
