UCC3583N Description

Short technical summary and product information.

The UCC3583N from Unitrode is a synchronizable secondary-side post regulator, engineered for precise regulation of auxiliary outputs in multi-output power supply systems. This device is suitable for both single-ended and center-tapped secondary circuits, offering an ideal replacement for complex magnetic amplifier regulated circuits.

 

Key features include leading-edge modulation, high-frequency operation exceeding 500kHz, and a high-current gate driver capable of 0.5A sink and 1.5A source. The controller operates from a floating power supply referenced to the output voltage being controlled and includes undervoltage lockout (UVLO), soft start, and an averaging current limit amplifier. The operating voltage range is 8.9V to 14V, with an operating temperature range of 0°C to 70°C.

 

Packaged in a 14-PDIP through-hole component, the UCC3583N is designed for applications requiring stable secondary-side regulation. Its design facilitates integration without requiring a gate drive transformer, simplifying system architecture. The device also incorporates protection circuitry and can achieve foldback operation under short circuit conditions when the current limit is programmed proportionally to the output voltage.
