UC3823A HIGH-SPEED PWM CONTROLLER

The UC3823A and UC3823B and the UC3825A and UC3825B family of PWM controllers are improved versions of the standard UC3823 and UC3825 family. Performance enhancements have been made to several of the circuit blocks. Error amplifier gain bandwidth product is 12 MHz, while input offset voltage is 2 mV.

UC3823A Features

* Improved versions of the UC3823/UC3825 PWMs

* Compatible with voltage-mode or current-mode control methods

* Practical operation at switching frequencies to 1 MHz

* 50-ns propagation delay to output

* High-current dual totem pole outputs (2-A peak)
