The UCD9222RGZR from Texas Instruments is a highly configurable, two-output, non-isolated DC/DC PWM controller. It supports a 4/6/8-bit parallel VID interface and operates with switching frequencies up to 2MHz, offering a duty-cycle resolution of 250 ps and closed-loop resolution up to 1mV.
This controller features a hardware-accelerated 3-pole/3-zero compensator with non-linear gain for improved transient performance. It supports multiple soft-start and soft-stop configurations, including prebias start-up, and offers voltage margining and sequencing capabilities. The device includes sync in/out pins for aligning DPWM clocks between multiple UCD92xx devices.
For monitoring, the UCD9222RGZR provides 12-bit digital monitoring of power supply parameters such as input and output current and voltage, temperature at each power stage, and auxiliary ADC inputs. It incorporates multiple levels of over-current fault protection, digitally monitored over and under-voltage fault protection, and over-temperature fault protection. The device operates from a single supply and is supported by the Fusion Digital Power Designer tool.
Packaged in a 48-VQFN (7x7) with surface mount, the UCD9222RGZR is suitable for applications in networking equipment, telecommunications, and FPGA, DSP, and memory power.
