TEA1761T

GreenChip synchronous rectiﬁer controller

Rev. 02 — 25 April 2007

Product data sheet

1. General description

The TEA1761T is a member of the new generation of Synchronous Rectiﬁer (SR)

controller ICs for switched mode power supplies. Its high level of integration allows the

design of a cost-effective power supply with a very low number of external components.

The TEA1761T is a controller IC dedicated for synchronous rectiﬁcation on the secondary

side of discontinuous conduction mode and quasi resonant ﬂyback converters. Besides

electronics for synchronous rectiﬁcation, it also has integrated circuitry for output voltage

and output current regulation.

The TEA1761T is fabricated in a Silicon On Insulator (SOI) process. This NXP SOI

process makes possible a wide range of operation.

2. Features

2.1 Distinctive features

I Combined synchronous rectiﬁcation and primary feedback control functionality

I Wide supply voltage range (8.6 V to 38 V)

I High level of integration, resulting in a very low external component count

I Wide opto coupler output voltage range (3.5 V to 38 V)

I Accurate internal voltage reference for voltage control (within 1 %)

I High driver output voltage of 10 V to drive all MOSFET brands to the lowest R_DSon

2.2 Green features

I Low current consumption

I High system efﬁciency from no load to full load

2.3 Protection features

I Undervoltage protection

I Internal over-temperature protection

3. Applications

The TEA1761T is intended for adapters. The device can also be used in all other

discontinuous conduction mode and quasi resonant ﬂyback systems that demand a highly

efﬁcient and cost-effective solution.
