TEA1752LT - GreenChip III SMPS control IC

Download the TEA1752LT datasheet PDF. This datasheet also covers the TEA1752T variant, as both devices belong to the same greenchip iii smps control ic family and are provided as variant models within a single manufacturer datasheet.

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.
