Its PMBus and I²C serial interfaces let the system monitor output voltage, current, and temperature in real time, and perform voltage margining without board spins. The 15.26 kHz to 2 MHz switching range covers ferrite-based magnetics for size optimization or low-frequency designs for loss reduction. ## Switching frequency and phase interleaving With a 100% max duty cycle and clock-sync capability, the UCD9220RGZT can interleave four phases to reduce input ripple current and output voltage ripple — a key advantage for noise-sensitive analog loads. The phase count directly scales the effective switching frequency at the output: four phases at 500 kHz each produce a 2 MHz effective ripple, shrinking the output filter. The -40°C to 110°C operating range covers industrial ambient conditions with margin for self-heating in the 48-VFQFN exposed-pad package. The tracking control feature allows the output to follow an external reference during power-up sequencing, preventing latch-up in multi-rail systems.","metaTitle":"Texas Instruments UCD9220RGZT Buck Controller, 4-Phase PWM","metaDescription":"Texas Instruments UCD9220RGZT 4-phase digital PWM buck controller with PMBus/I²C telemetry.
