Switching frequency spans 85 kHz to 1.15 MHz, letting the designer trade transformer size against switching losses; the 4.7 V to 17 V supply range mates with common 5 V or 12 V bias rails in telecom and industrial power supplies. Two PWM outputs drive the primary-side FETs in bridge configurations without external phase-shift logic, and the built-in synchronous rectifier control improves efficiency at low output voltages by replacing Schottky catch diodes. ## 85 kHz–1.15 MHz switching — design flexibility for magnetics sizing The 85 kHz to 1.15 MHz switching range lets the power-stage designer choose a smaller transformer core at higher frequency or lower switching losses at the low end — a single BOM line adapts across multiple power levels. Operating temperature is rated -40°C to 125°C junction, which covers base-station power amplifiers, motor-drive bias supplies, and outdoor telecom equipment where ambient heat pushes junction temperatures above 105°C. Control features include current limit, enable, frequency control, ramp, and soft start — these reduce external component count for sequencing, overcurrent protection, and startup shaping. ## 20-TSSOP package — footprint and board integration Housed in a 20-TSSOP with 4.40 mm body width (supplier device package 20-TSSOP), the UCC28250PW fits compact board layouts where every millimeter of board edge matters — the 0.65 mm pin pitch is hand-solderable with a fine tip. Supplied in tube format — the standard 20-TSSOP tube quantity suits prototype and low-volume production runs; for reel quantities check the alternate ordering code suffix.","metaTitle":"Texas Instruments UCC28250PW PWM Controller, 85kHz-1.15MHz","metaDescription":"Active-production multi-topology PWM controller from TI.
