NCP3064数据手册集成电路（IC）的稳压器-DC-DC开关稳压器规格书PDF

描述 Description

The NCP3064 Buck Boost Inverting Switching Regulator is a higher frequency upgrade to the popular MC33063A and MC34063A monolithic dc-dc hysteretic converters. These Buck Boost Inverting Switching Regulators 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 (buck), Step-Up (boost) and Voltage-Inverting applications with a minimum number of external components. It has ON/OFF feature which puts the device into a low power (
