MC34271 Overview
Key Features
- a very low standby bias current of 5.0 µA, and an operating current of 7.0 mA capable of supplying output currents in excess of 200 mA
- Both devices have three additional features
- The first is an ELD Output that can be used to drive a backlight or a liquid crystal display
- It allows use of mixed logic circuitry and provides a voltage bias for N–Channel load control MOSFETs
- The third feature is an Enable input that allows a logic level signal to turn–“off” or turn–“on” both switching regulators
