UCC2583D Description

Short technical summary and product information.

The UCC2583D from Texas Instruments is a synchronizable secondary side post regulator. It is designed for precision regulation of auxiliary outputs in multiple output power supplies, making it useful for both single-ended and center-tapped secondary circuits. This device is an ideal replacement for complex magnetic amplifier regulated circuits.

 

Key features include leading edge modulation, high frequency operation (>500kHz), and a high current gate driver capable of 0.5A sink and 1.5A source. The UCC2583D operates with a voltage range of 8.9V to 14V and a maximum duty cycle of 95%. It is specified for an operating temperature range of -40°C to 85°C.

 

The regulator operates from a floating power supply referenced to the output voltage being controlled. It incorporates an undervoltage lockout (UVLO) circuit, a soft start circuit, and an averaging current limit amplifier. The current limit can be programmed to be proportional to the output voltage for foldback operation, minimizing dissipation under short circuit conditions.

 

Packaged in a 14-SOIC (0.154", 3.90mm Width) surface mount package, the UCC2583D is suitable for various power supply applications requiring precise secondary-side regulation.
