TEA1521P - SMPS

Download the TEA1521P datasheet PDF. This datasheet also covers the TEA1520P variant, as both devices belong to the same smps family and are provided as variant models within a single manufacturer datasheet.

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.

Key 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.
