UC3875N Descrizione generale

When it comes to power supply control, the UC3875N stands out as a top-notch pulse width modulation controller IC crafted by Texas Instruments. Its exceptional abilities include operating at a fixed frequency of 100kHz and providing adjustable overcurrent, overvoltage, and overtemperature protection for an extra layer of security. The UC3875N also boasts a voltage feedforward circuit that enhances line regulation, a soft-start feature that reduces in-rush current, and a programmable dead-time for improved power efficiency
