Description
The ST UC3842BN is a high performance current-mode PWM controller IC that is designed to work with low input voltage systems. Its primary function is to convert DC voltage into regulated DC output voltage using an external power MOSFET and inductor. The device delivers a fixed frequency pulse width modulation signal to the power switch that is adjustable to allow for efficient power regulation of the output. The integrated oscillator, error amplifier and PWM control circuitry provide stable and reliable performance for use in a variety of applications including switch mode power supplies, DC to DC converters, and battery chargers.
The UC3842BN is optimized for use in low voltage applications, with inputs that can accommodate an input voltage range of 7V to 25V DC. It features adjustable frequency operation ranging from 50kHz to 1MHz and is capable of providing a maximum output power of up to 100W. The device incorporates a range of advanced protection features including cycle-by-cycle current limiting and thermal shutdown to ensure safe and reliable operation. Overall, the UC3842BN is a highly effective PWM controller that provides exceptional performance and efficiency over a wide range of input and load conditions
