Texas Instruments Special Purpose Regulators UCC3882DW

The UCC3882DW is a synchronous controller designed for voltage regulation, specifically compatible with Intel's 5-bit VID code. It features a combined digital-to-analog converter (DAC) and voltage monitoring circuitry, allowing for precise output voltage adjustments from 1.8VDC to 3.5VDC in 100 mV steps, and from 1.3VDC to 2.05VDC in 50 mV steps. The device supports both 5V and 12V systems and is optimized for high-performance applications with a 1% accuracy specification for the DAC/reference combination. Key functionalities include foldback current limiting, undervoltage lockout, and overvoltage protection, which enhance system reliability. The UCC3882DW operates with a programmable oscillator frequency up to 700 kHz and features low offset current sense amplifiers, minimizing power loss. It is housed in a 28-pin wide body surface mount package and is rated for operation between 0¬8C and 70¬8C. This product is suitable for applications requiring efficient power management with minimal external components.
