UC2825B - High Speed PWM Controller

Download the UC2825B datasheet PDF. This datasheet also covers the UC2 variant, as both devices belong to the same high speed pwm controller family and are provided as variant models within a single manufacturer datasheet.

General Description

The UC3823A & B and the UC3825A & B family of PWM control ICs are improved versions of the standard UC3823 & UC3825 family.

Performance enhancements have been made to several of the circuit blocks.

Error amplifier gain bandwidth product is 12MHz while input offset voltage is 2mV.

Key Features

  • Improved versions of the UC3823/UC3825 PWMs Compatible with Voltage or Current-Mode Topologies Practical Operation at Switching Frequencies to 1MHz 50ns Propagation Delay to Output High Current Dual Totem Pole Outputs (2A Peak) Trimmed Oscillator Discharge Current Low 100µA Startup Current Pulse-by-Pulse Current Limiting Comparator Latched Overcurrent Comparator With Full Cycle Restart.
