onsemi NCP3063
The NCP3063 Series is a higher frequency upgrade to the popular MC34063A and MC33063A monolithic DC−DC converters. These devices consist of an internal temperature compensated reference, comparator, a controlled duty cycle oscillator with an active current limit circuit, a driver and a high current output switch. This series was specifically designed to be incorporated in Step−Down, Step−Up and Voltage−Inverting applications with a minimum number of external components.FEATURES
● Operation to 40 V Input● Low Standby Current
● Output Switch Current to 1.5 A
● Output Voltage Adjustable
● Frequency Operation of 150 kHz
● Precision 1.5% Reference
● New
