TEA1521T - SMPS

This page provides the datasheet information for the TEA1521T, a member of the TEA1520P SMPS family.

Datasheet Summary

Description

The TEA152x family STARplug is a Switched Mode Power Supply (SMPS) controller IC that operates directly from the rectified universal mains.

It is implemented in the high-voltage EZ-HV SOI process, combined with a low-voltage Bipolar Complementary Metal-Oxide Semiconductor (BiCMOS) process.

Features

Designed for general purpose supplies up to 30 W.
Integrated power switch: TEA1520x: 48 Ω; 650 V TEA1521x: 24 Ω; 650 V TEA1522x: 12 Ω; 650 V TEA1523P: 6.5 Ω; 650 V.
Operates from universal AC mains supplies (80 V to 276 V).
Adjustable frequency for flexible design.
RC oscillator for load insensitive regulation loop constant.
Valley switching for minimum switch-on loss.
Frequency reduction at low power output makes low standb.

TEA152x SMPS ICs for low-power systems Rev. 04 — 14 September 2010 Product data sheet 1. General description The TEA152x family STARplug is a Switched Mode Power Supply (SMPS) controller IC that operates directly from the rectified universal mains. It is implemented in the high-voltage EZ-HV SOI process, combined with a low-voltage Bipolar Complementary Metal-Oxide Semiconductor (BiCMOS) process. The device includes a high-voltage power switch and a circuit for start-up directly from the rectified mains voltage. A dedicated circuit for valley switching is built in, which makes a very efficient slim-line electronic power-plug concept possible. In its most basic version of application, the TEA152x family acts as a voltage source. Here, no additional secondary electronics are required.
