NCP3155A, NCP3155B
3 A Synchronous Buck Regulator
The NCP3155 is a DC/DC synchronous switching regulator with fully integrated power switches and full fault protection.
The switching frequency of 1 MHz and 500 kHz allows the use of small filter components, which results in smaller board space and reduced BOM cost.
Available in a SOIC-8 package.
