The UCD9222RGZT from Texas Instruments is a fully configurable, two-output, non-isolated DC/DC PWM controller designed for non-isolated power applications. It supports switching frequencies up to 2MHz with a high duty-cycle resolution of 250 ps and up to 1mV closed-loop resolution.
This device integrates dedicated circuitry for DC/DC loop management and supports multiple Voltage Identification (VID) modes, including 4-bit parallel, 6-bit, and 8-bit serial interfaces. It features a hardware-accelerated, 3-pole/3-zero compensator for improved transient performance and supports various soft-start, soft-stop, margining, and sequencing configurations.
The UCD9222RGZT is housed in a 48-VQFN (7x7) package and is suitable for surface mounting. It operates over a temperature range of -40°C to 125°C (TJ) and requires an operating voltage between 3V and 3.6V. The controller offers 12-bit digital monitoring of power supply parameters and includes multiple levels of over-current, over-voltage, and over-temperature fault protection.
Applications for this controller include networking equipment, telecommunications equipment, and FPGA, DSP, and memory power supplies. It is supported by the Texas Instruments Fusion Digital Power Designer tool for configuration, monitoring, and simulation.
