UCC28512 Datasheet Advanced Pfc/pwm Combination Controllers

Manufacturer: Texas Instruments

Overview: UCC28510, UCC28511, UCC28512, UCC28513, UCC28514, UCC28515, UCC28516, UCC28517 SLUS517C − DECEMBER 2002 − REVISED SEPTEMBER 2005 ADVANCED PFC/PWM COMBINATION.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The UCC28510 series of combination PFC/PWM controllers provide complete control functionality for any off-line power system requiring compliance with the IEC1000−3−2 harmonic reduction requirements.

By combining the control and drive signals for the PFC and the PWM stages into a single device, significant performance and cost benefits are gained.

By managing the modulation mechanisms of the two stages (leading-edge modulation for PFC and trailing-edge modulation for PWM), the ripple current in the boost capacitor is minimized.

Key Features

  • D Provides Control of PFC and PWM Power Stages In One Device D Leading-Edge PFC, Trailing-Edge PWM Modulation for Reduced Ripple D Built-In Sequencing of PFC and PWM Turn-On D 2-A Source and 3-A Sink Gate Drive for Both PFC and PWM Stages D Typical 16-ns Rise Time and 7-ns Fall Time into 1-nF Loads PFC Features.
  • Average-Current-Mode Control for Continuous Conduction Mode Operation.
  • Highly-Linear Multiplier for Near-Unity Power Factor.
  • Input Voltage Feedforward Implemen.
