Download the UCC3882 datasheet PDF.
This datasheet also covers the UCC2882 variant, as both devices belong to the same average current mode synchronous controller family and are provided as variant models within a single manufacturer datasheet.
General Description
The UCC3882 combines high precision reference and voltage monitoring circuitry with average current mode PWM synchronous rectification controller circuitry to power high-end microprocessors with a minimum of external components.
Key Features
Combined DAC/Voltage Monitor and PWM
with Synchronous Rectification Functions.
5-Bit Digital-to-Analog (DAC) Converter.
1% DAC/Reference Combined Accuracy.
Compatible with 5V and 12V Systems and
12V-only Systems.
Low Offset Current Sense Amplifier.
Programmable Oscillator Frequency Practical
to 700kHz.
