Leaded Buck Regulator Evaluation Board

The NCP3063 Series is a performance enhancement to the popular MC33063 and MC34063 monolithic dc-dc converters. These devices consist of an internal temperature compensated reference, comparator, controlled duty cycle oscillator with an active current limit circuit, driver and high output current switch. This controller was specifically designed to be incorporated in step-down, step-up, or voltage inverting applications with a minimum number of external components. The NCP3063 Buck Evaluation Board is a 250 kHz maximum switching frequency board with 3.3V output. The output is capable of loads from 0.2 A to 0.8 A with the efficiency higher than 73% (at 150 kHz). The input voltage for the 3.3V output is 7V to 15V.
