Unitrode
Download the UCC3882-1 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.
