MIC38C43 - BiCMOS Current-Mode PWM Controllers

Download the MIC38C43 datasheet PDF. This datasheet also covers the MIC38C42 variant, as both devices belong to the same bicmos current-mode pwm controllers family and are provided as variant models within a single manufacturer datasheet.

General Description

The MIC38C4x are fixed frequency, high performance, current-mode PWM controllers.

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

Key Features

  • a trimmed oscillator discharge current and bandgap reference. The MIC38C4x denotes 8-pin plastic DIP, SOIC, and MSOP packages. MIC384Cx-1 denotes 14-pin plastic DIP and SOIC packages. 8-pin devices feature small size, while 14pin devices separate the analog and power connections for improved perfomance and power dissipation. 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.

MIC38C42/3/4/5 Micrel, Inc. MIC38C42/3/4/5 BiCMOS Current-Mode PWM Controllers General Description The MIC38C4x 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 50µA typical and operating current has been reduced to 4.0 mA typical.
