UC1825J Description

Short technical summary and product information.

The UC1825J from Unitrode is a high-speed Pulse Width Modulation (PWM) controller optimized for high-frequency switched-mode power supply applications. It is designed for use in both current-mode and voltage-mode systems, with capabilities for input voltage feed-forward.

 

Key electrical specifications include a maximum duty cycle of 80% and a practical operation switching frequency up to 1MHz. It features a 50ns propagation delay to the output and high current dual totem pole outputs capable of 1.5A peak current. The controller also includes a wide bandwidth error amplifier, fully latched logic with double pulse suppression, and pulse-by-pulse current limiting.

 

Protection features include under-voltage lockout with hysteresis and low start-up current of 1.1mA. The UC1825J is available in multiple package options: CDIP (J), CFP (W), and LCCC (FK). Its design prioritizes minimizing propagation delays and maximizing error amplifier bandwidth and slew rate for efficient power supply operation.
