MIC38HC43, MIC38HC45, BiCMOS 1A Current-Mode PWM Controllers

MIC38HC42/3/4/5 Micrel MIC38HC42/3/4/5 BiCMOS 1A Current-Mode PWM Controllers Final Information General .
The MIC38HC4x family are fixed frequency current-mode PWM controllers with 1A drive current capability.

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

Applications

* Current-mode, off-line, switched-mode power supplies Current-mode, dc-to-dc converters. Step-down “buck” regulators Step-up “boost” regulators Flyback, isolated regulators Forward converters Synchronous FET converters Functional
