The UCC25630-1DDBR is working on an all-or-nothing control principle. It has a controller pulse generator to produce a carrier signal under the desired operating voltage. The reference voltage is received from the transformer through the feedback network and is then compared with the voltage sample from the transformer output to get the desired output voltage. The currentMeter output is then updated with a sample output voltage sample from the transformer. The PWM pin is modulated according to the Volatility signal from the transformer, and it controls the output power. The high voltage MOSFET switches connected to the PWM signals the input voltage into the transformer output.

The UCC25630-1DDBR features Integrated dual-channel Line current sensing, Bulk voltage control for output voltage tracking, frequency dithering for reduced component stress, programmable output voltage slew rate, PFM/PWM Mode selection and selectable currentshare mode. All these features contribute to increased efficiency and circuit optimization even with heavy loads.
