TEA1532 Datasheet Greenchip Smps Control Ic

Manufacturer: NXP Semiconductors

Overview: TEA1532 GreenChip™II SMPS control IC Rev. 01 — 28 May 2004 Preliminary data sheet 1.

General Description

The GreenChip™II is the second generation of green Switched Mode Power Supply (SMPS) controller ICs.

Its high level of integration allows the design of a cost effective power supply with a very low number of external ponents.

The TEA1532 can also be used in fixed frequency, Continuous Conduction Mode (CCM) converter designs for low voltage, high current applications.

Key Features

  • 2.1 Distinctive features s s s s Universal mains supply operation (70 V to 276 V AC) High level of integration, resulting in a very low external component count Fixed frequency Continuous Conduction Mode (CCM) operation capability Quasi-Resonant (QR) Discontinuous Conduction Mode (DCM) operation capability. 2.2 Green features s Valley or zero voltage switching for minimum switching losses in QR operation s Cycle skipping mode at very low loads; input power.
