TEA1752T - GreenChip III SMPS control IC

General Description

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

The TEA1752T and TEA1752LT combine a controller for Power Factor Correction (PFC) and a flyback controller.

Key Features

  • 2.1 Distinctive features.
  • Integrated PFC and flyback controller.
  • Universal mains supply operation (70 V (AC) to 276 V (AC)).
  • Dual boost PFC with accurate maximum output voltage (NXP Semiconductors patented, US patent number: US7575280).
  • High level of integration, resulting in a very low external component count and a cost-effective design.
  • Adjustable PFC switch-off delay 2.2 Green features.
  • On-chip start-up current source NXP Semiconductors.

TEA1752T; TEA1752LT GreenChip III SMPS control IC Rev. 02 — 24 June 2010 Product data sheet 1. General description www.DataSheet4U.com The GreenChip III is the third generation of green Switched Mode Power Supply (SMPS) controller ICs. The TEA1752T and TEA1752LT combine a controller for Power Factor Correction (PFC) and a flyback controller. The high level of integration facilitates the design of a cost-effective power supply using a minimum number of external components. The special built-in green functions provide high efficiency at all power levels. This applies to quasi-resonant operation at high power levels, quasi-resonant operation with valley skipping and reduced frequency operation at lower power levels. At low power levels, the PFC switches off to maintain high efficiency.
