The UC1825B-SP is a high-speed PWM controller and designed to use in either current-mode or voltage-mode system. Particular care is given to minimizing propagation delays through the comparators and logic circuitry while maximizing bandwidth and slew rate of the error amplifier.

The UC1825B-SP features totem pole outputs designed to source and sink high peak currents from capacitive loads.

The UC1825B-SP operates from supply of 10V to 30V, with low start up current of 1.1mA. The devices are specified over the extended operating temperature range of –55°C to 125°C and are offered in a 16-pin CFP package.
