General Description

The UC1825 family of PWM control ICs is optimized for high frequency switched mode power supply applications.

Particular care was given to minimizing propagation delays through the comparators and logic circuitry while maximizing bandwidth and slew rate of the error amplifier.

This controller is designed for use in either current-mode or voltage mode systems with the capability for input voltage feed-forward.

Key Features

Compatible with Voltage or Current Mode Topologies.
Practical Operation Switching Frequencies to 1MHz.
50ns Propagation Delay to Output.
High Current Dual Totem Pole Outputs (1.5A Peak).
Wide Bandwidth Error Amplifier.
Fully Latched Logic with Double Pulse Suppression.
Pulse-by-Pulse Current Limiting.
Soft Start / Max. Duty Cycle Control.
Under-Voltage Lockout with Hysteresis.
Low Start Up Current (1.1mA).
