MIC3833 Datasheet Current-fed Pwm Controllers

Manufacturer: Micrel Semiconductor

Overview: www.DataSheet4U.com MIC3832/3833 Micrel MIC3832/3833 Current-Fed PWM Controllers Not Recommended for New Designs.

This datasheet includes multiple variants, all published together in a single manufacturer document.

Datasheet Details

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

The MIC3832/3

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.
