The UC3879N is a phase-shift resonant controller designed for half-bridge power stage applications. It supports programmable output turn-on delays and operates effectively at switching frequencies up to 300 kHz, with an oscillator capable of exceeding 600 kHz. The device can be configured for voltage mode or current mode control, providing flexibility in various applications. Key features include a 10-MHz error amplifier, undervoltage lockout, overcurrent protection, and soft start control, which enhance its reliability and performance. The UC3879N is available in a 20-pin PDIP package and operates within a temperature range of 0¬8C to 70¬8C. This product is suitable for engineers looking for a robust solution for DC-DC conversion in power management systems.
