TEA1552 - HV start-up flyback controller

Datasheet Summary

Description

The GreenChipII is the second generation of green Switched Mode Power Supply (SMPS) control ICs operating directly from the rectified universal mains.

A high level of integration leads to a cost effective power supply with a very low number of external components.

Features

  • Distinctive features:.
  • Universal mains supply operation (70 V AC to 276 V AC).
  • High level of integration, giving a very low external component count.
  • Green features:.
  • Valley or zero voltage switching for minimum switching losses.
  • Efficient quasi-resonant operation at high power levels.
  • Frequency reduction at low power standby for improved system efficiency (.

TEA1552 HV start-up flyback controller for DCM or QR mode; 125 kHz fosc(h); standby output signal Rev. 3.1 — 21 June 2012 Product data sheet 1. General description The GreenChipII is the second generation of green Switched Mode Power Supply (SMPS) control ICs operating directly from the rectified universal mains. A high level of integration leads to a cost effective power supply with a very low number of external components. The special built-in green functions allow the efficiency to be optimum at all power levels. This holds for quasi-resonant operation at high power levels, as well as fixed frequency operation with valley switching at medium power levels. At low power (standby) levels, the system operates at reduced frequency and with valley detection.
