General Description

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 where high efficiency is required.

Overview

MIC38HC42/3/4/5 Micrel MIC38HC42/3/4/5 BiCMOS 1A Current-Mode PWM Controllers Final Information.

Key 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 20ns output rise and 15ns output fall times.
  • 40°C to +85°C temperature range exceeds UC284x specifications.
  • High-performance, low-power BiCMOS Process.
  • Ultralow start.
