MIC38HC43 - BiCMOS 1A Current-Mode PWM Controllers

Download the MIC38HC43 datasheet PDF. This datasheet also covers the MIC38HC45 variant, as both devices belong to the same bicmos 1a current-mode pwm controllers family and are provided as variant models within a single manufacturer datasheet.

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.

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.

MIC38HC42/3/4/5 Micrel MIC38HC42/3/4/5 BiCMOS 1A Current-Mode PWM Controllers Final Information 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. Undervoltage lockout circuitry allows the ’42 and ’44 versions to start up at 14.5V and operate down to 9V, and the ’43 and ’45 versions start at 8.4V with operation down to 7.6V. All versions operate up to 20V.
