概要 UC2825AN
The UC2825AN is a high-performance PWM controller designed for use in push-pull, current-fed, and half-bridge power supplies. It features a wide input voltage range of 8V to 35V, making it suitable for a variety of applications. With a frequency range of 10kHz to 500kHz, it offers flexibility in designing power supplies for different requirements.The UC2825AN includes a precision voltage reference, an error amplifier, a pulse-width modulation comparator, and a driver for external power devices. It also has built-in protection features such as overcurrent protection, undervoltage lockout, and thermal shutdown to ensure safe operation of the power supply.This PWM controller has a maximum duty cycle of 50% and can provide a constant frequency operation at all duty cycles, making it ideal for high-efficiency power supplies. It can deliver up to 1A of output current and has a high current capability for driving power MOSFETs or IGBTs.
