MIC3833 - Current-Fed PWM Controllers

Download the MIC3833 datasheet PDF. This datasheet also covers the MIC3832 variant, as both devices belong to the same current-fed pwm controllers family and are provided as variant models within a single manufacturer datasheet.

General Description

The MIC3832 and MIC3833 are unique PWM controllers designed for current-fed, multiple-output or push-pull, switched-mode power supply applications.

Key Features

  • UVLO (undervoltage lockout) with hysteresis, soft start with a programmable time constant, cycle-by-cycle current limiting, a PWM latch to prevent multiple outputs due to noise or ringing, and front-edge blanking. Current-fed topologies eliminate core saturation problems caused by shoot through (cross conduction) of push-pull circuits and reduce stress on the switching transistors. The MIC3832/3 has one PWM stage capable of operating up to 500kHz and two output stages, Q and Q, that operate at o.
