UCC3884 Product details

Description

The UCC3884 is a high performance current mode PWM controller intended for single ended switch mode power supplies.

The chip implements a frequency foldback scheme that decreases the oscillator frequency as the output voltage falls below a programmed value.

Features

1.
Frequency Foldback Reduces Operating Frequency Under Fault Conditions.
Accurate Programmable Volt-Second Clamp.
Programmable Maximum Duty Cycle Clamp.
Oscillator Synchronization.
Overcurrent Protection.
Shutdown With Full Soft Start.
Wide Gain Bandwidth Amplifier (GBW > 2.5 MHz).
Current Mode Operation.
Precision 5-V Reference.
