UCD9244RGCR Description

Short technical summary and product information.

The UCD9244RGCR from Texas Instruments is a fully configurable, four-output, non-isolated DC/DC PWM controller. It supports switching frequencies up to 2MHz with a duty-cycle resolution of 250 ps and a closed-loop resolution of up to 1mV. This device is designed for applications requiring precise voltage regulation and transient response.

Key features include a hardware-accelerated 3-pole/3-zero compensator for improved transient performance and support for multiple soft-start and soft-stop configurations. The controller also offers voltage margining and sequencing capabilities, along with synchronization between multiple UCD92xx devices.

For monitoring, the UCD9244RGCR provides 12-bit digital monitoring of input and output current and voltage, temperature at each power stage, and auxiliary ADC inputs. It incorporates multiple levels of over-current, over-voltage, and over-temperature fault protection. The device operates from a single supply and is supported by Texas Instruments' Fusion Digital Power Designer tool.

The UCD9244RGCR is packaged in a 64-VQFN (9x9 mm) surface-mount package, suitable for space-constrained designs. Its operating temperature range is -40°C to 125°C.
