MIC38C42A - BiCMOS Current-Mode PWM Controllers

Datasheet Summary

Description

The MIC38C4xA are fixed frequency, high performance, current-mode PWM controllers.

Micrel’s BiCMOS devices are pin compatible with 384x bipolar devices but feature several improvements.

Features

  • a trimmed oscillator discharge current and bandgap reference. The MIC38C4xA family is available in 8-pin SOIC and MSOP8 (MM8) package options For fast rise and fall times and higher output drive, refer to the MIC38HC4x. Features.
  • Fast 40ns output rise and 30ns output fall times.
  • 40°C to +85°C temperature range meets UC284x specifications.
  • High-performance, low-power BiCMOS Process.
  • Ultralow start-up current (100µA typical).
  • Low operating cur.

MIC38C42A/43A/44A/45A Micrel, Inc. MIC38C42A/43A/44A/45A BiCMOS Current-Mode PWM Controllers General Description The MIC38C4xA are fixed frequency, high performance, current-mode PWM controllers. Micrel’s BiCMOS devices are pin compatible with 384x bipolar devices but feature several improvements. 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. When compared to bipolar 384x devices operating from a 15V supply, start-up current has been reduced to 50 µA typical and operating current has been reduced to 4.0mA typical.
