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.

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

Key Features

  • Fast 40 ns Output Rise and 30 ns Output Fall Times.
  • 40°C to +85°C Ambient Temperature Range Meets UC284x Specifications.
  • High-Performance, Low-Power BiCMOS Process.
  • Ultra-Low Start-Up Current (50 μA Typical).
  • Low Quiescent Operating Current (4 mA Typical).
  • CMOS Outputs with Rail-to-Rail Swing.
  • Up to 500 kHz Current-Mode Operation.
  • Trimmed 5V Bandgap Reference.
  • Pin-for-Pin Compatible with UC3842/3843/3844/3.
