TEA1795T - Brand New NXP Semiconductors DC DC Switching Controllers
-
Description
The TEA1795T is a member of the new generation of Synchronous Rectifier (SR) controller ICs for switched mode power supplies. Its high level of integration enables the design of a cost-effective power supply with a minimum number of external components.
Specifications and features
Distinctive features
■ Accurate synchronous rectification functionality
■ Wide supply voltage range (8.5 V to 38 V)
■ Separate sense inputs for sensing the drain and source voltage of each SR MOSFET
■ High level of integration, resulting in a minimum external component count
■ High driver output voltage of 10 V to drive all MOSFET brands to the lowest RDSonApplication Scenarios
The TEA1795T is intended for resonant power supplies. In such applications, it can drive two external synchronous rectifier MOSFETs which replace diodes for the rectification of the voltages on the two secondary windings of the transformer. It can be used in applications such as:
■ Adapters
■ ATX power supplies
■ Server power supplies
■ LCD television
■ Plasma televisionComparison
