MC33063AD

Inverting DC/DC Converters Integrated Switch, Texas Instruments### 直流/直流开关调节器转换器（集成开关），Texas InstrumentsTexas Instruments 的此系列高度集成的高效开关稳压器包括步升（升压）、步降（降压）、步升/降（增压/降压）和反相类型，为每个直流稳压器应用提供高效的解决方案。

The is a boost/buck/inverting switching regulator in 8 pin SOIC package. It is an easy to use regulator containing all primary circuitry needed for building simple DC to DC converters. The MC33063AD regulator primarily consist of an internal temperature compensated reference, comparator, oscillator, PWM controller with active current limiting, driver and high current output switch. This device requires minimal external components to build converters in boost, buck and inverting topologies.
