Product specification

TEA152x family

FEATURES

• Designed for general purpose supplies up to 50 W

• Integrated power switch:

– TEA1520: 48 Ω; 650 V

– TEA1521: 24 Ω; 650 V

– TEA1522: 12 Ω; 650 V

– TEA1523: 6.5 Ω; 650 V

– TEA1524: 3.4 Ω; 650 V.

• Operates from universal AC mains supplies

(80 to 276 V)

• Adjustable frequency for flexible design

• RC oscillator for load insensitive regulation loop

constant

• Valley switching for minimum switch-on loss (not

implemented in TEA152xAJM versions)

• Frequency reduction at low power output makes low

standby power possible (<100 mW)

• Adjustable overcurrent protection

• Under voltage protection

• Temperature protection

• Short circuit winding protection

• Simple application with both primary and secondary

(opto) feedback

• Available in 8-pin DIP, 14-pin SO and 9-pin DBS

packages.

GENERAL DESCRIPTION

The TEA152x family 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

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 (not

implemented in TEA152xAJM versions), which makes a

very efficient slim-line electronic powerplug concept

possible.

In its most basic version of application, the TEA152x family

acts as a voltage source. Here, no additional secondary

electronics are required. A combined voltage and current

source can be realized with minimum costs for external

components. Implementation of the TEA152x family

renders an efficient and low cost power supply system.
