UC2525AN

Description

The UC2525AN is a dual 0.4A, 400kHz PWM controller from Texas Instruments. It's designed for DC-DC converters, motor control, and other applications that require high-frequency switching. The device features an adjustable oscillator range of 100Hz to 500kHz, separate oscillator sync terminal, and adjustable dead-time control. The UC2525AN has a wide operating voltage range of 8V to 35V and can handle up to 400 kHz PWM frequency. It also includes internal soft start, pulse-by-pulse shutdown, and input undervoltage lockout with hysteresis for safe operation. This device is suitable for use in a variety of applications, including power supplies, motor control systems, and other high-frequency switching circuits. Its compact PDIP-16 package makes it easy to integrate into designs.
