UCD9240RGCR

The Texas Instruments UCD9240RGCR is a Digital Point of Load System Controller designed for specialized power management applications. This device operates within a temperature range of -40°C to 110°C and supports a supply voltage from 3V to 3.6V.

Key features include the ability to control up to four voltage rails and eight phases, with switching frequencies up to 2MHz. It offers a 250 ps duty-cycle resolution and up to 1mV closed-loop resolution. The controller supports multiple soft-start and soft-stop configurations, voltage tracking, margining, and sequencing.

Packaged in a 64-VQFN (9x9) form factor, the UCD9240RGCR is suitable for surface mount applications. It provides 12-bit digital monitoring of power supply parameters, including input/output current and voltage, and temperature at each power stage. The device also includes multiple levels of overcurrent, over/undervoltage, and overtemperature fault protection.

This controller is supported by the Fusion Digital Power Designer tool, which aids in simulating, configuring, and monitoring power supply performance. Applications include industrial equipment, networking, telecommunications, servers, storage systems, and power for FPGAs, DSPs, and memory.
