UC3825AN TI PWM Controller | 16-PDIP | 1MHz, Dual Output

Product Overview

The UC3825AN from Texas Instruments is a high-speed, dual-output, current-mode PWM controller designed for off-line and DC-to-DC converter applications. It operates at a fixed frequency up to 1 MHz and features a 1A peak gate drive capability. The device is housed in a 16-pin PDIP package, making it suitable for through-hole assembly. With its advanced protection features including under-voltage lockout (UVLO), soft-start, and programmable slope compensation, the UC3825AN provides reliable and efficient power conversion.
