TEA1755T - HV start-up DCM/QR flyback controller

Description

The GreenChip is the latest generation of green Switched Mode Power Supply (SMPS) controller ICs.

The TEA1755T combines a controller for Power Factor Correction (PFC) and a flyback controller.

Features

  • 2.1 Distinctive features.
  • Integrated PFC and flyback controller.
  • Universal mains supply operation between 70 V (AC) to 276 V (AC).
  • Dual-boost PFC with accurate maximum output voltage (NXP Semiconductors patented).
  • High level of integration, results in cost-effective designs with very low external component counts.
  • Adjustable PFC switch off delay.
  • External PFC switch on and switch off override.
  • Accurate PFC switch on and switch off control (NXP Semiconductors p.

TEA1755T HV start-up DCM/QR flyback controller with integrated DCM/QR PFC controller Rev. 1.1 — 13 March 2015 Product data sheet 1. General description The GreenChip is the latest generation of green Switched Mode Power Supply (SMPS) controller ICs. The TEA1755T combines a controller for Power Factor Correction (PFC) and a flyback controller. Its high level of integration enables cost-effective power supply design using a very low number of external components. The PFC operates in Quasi-Resonant (QR) or Discontinuous Conduction Mode (DCM), with valley switching. The specially built-in green functions provide high efficiency at all power levels. At high power levels the flyback operates in QR mode or DCM with valley detection.
