38HC43 Datasheet (Micrel Semiconductor)

38HC43, MIC38HC43

The MIC38HC4x family are fixed frequency current-mode PWM controllers with 1A drive current capability.

Micrel’s BiCMOS devices are pin-compatible with 384x bipolar devices.

Their high output drive, with fast rise and fall times, combined with low startup current make it an ideal PWM controller wher

38HC43 Features

* a trimmed oscillator discharge current and bandgap reference. MIC38HC4x-1 is available in 14-pin plastic DIP and SOIC packages. 8-pin devices feature small size, while 14-pin devices separate the analog and power connections for improved performance and power dissipation. Features

* Fast 20
