Product Description
The NCP3064 Series is a higher frequency upgrade to the popular MC33063A and MC34063A monolithic DC-DC hysteretic converters. These devices consist of an internal temperature compensated reference, comparator, controlled duty cycle oscillator with an active current limit circuit, driver and 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. It has ON/OFF feature which puts the device into a low power (<100µA) standby state. See NCP3063 for product without ENABLE feature.
