UC1823A HIGH-SPEED PWM CONTROLLER

UC1823A Description

UC1823A, UC2823A, UC2823B, UC3823A, UC3823B UC1825A, UC2825A, UC2825B, UC3825A, UC3825B SLUS334F * AUGUST 1995 * REVISED AUGUST 2022 H.
The UC3823A and UC3823B and the UC3825A and UC3825B family of PWM controllers are improved versions of the standard UC3823 and UC3825 family.

UC1823A 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)

UC1823A Applications

* The output drivers are redesigned to actively sink current during UVLO at no expense to the startup current specification. In addition each output is capable of 2-A peak currents during transitions. Functional improvements have also been implemented in this family. The UC3825 shutdown comparator i
