Overview
Description
The UC1823 family of PWM control ICs is optimized for high-frequency switched-mode power supply applications. It features a totem pole output designed to source and sink high peak currents from capacitive loads, such as the gate of a power MOSFET. The on-state is defined as a high level.

Features
Compatible with voltage or current-mode topologies
50ns propagation delay to output
High current totem pole output (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)
Trimmed bandgap reference (5.1V ±1%)

Applications
Switching frequencies to 1.0MHz
Practical operation
Current limit reference (pin 11) is a DC input voltage to the current limit comparator. Consult specifications for details.
