TEA1620P STARplug TM Rev. 01 — 17 March 2004 Product data sheet
1. General description
The TEA1620P 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 high voltage power switch and 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 TEA1620P acts as voltage source. Here, no additional secondary electronics are required. combined voltage and current source can be realized with minimum costs for external components. Implementation of the TEA1620P renders an efficient and low cost power supply system.
2. Features
Designed for general purpose supplies Integrated power switch: 48 Ω and 650 Operates from universal AC mains supplies: 80 V to 276 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 for low standby power: <100 m W Adjustable overcurrent protection Undervoltage protection Temperature protection Short winding protection Safe restart mode for system fault conditions Simple application with both primary and secondary (opto) feedback Available in 8-pin DIP package.
3. Applications
Chargers Adapters TV and monitor standby supplies PC peripherals.

Frequently Asked Questions
What universal mains voltage range can this controller operate from?
It operates from universal AC mains supplies ranging from 80 V to 276 V.
Which key protection features are available for system reliability?
It includes adjustable overcurrent, undervoltage, temperature, short winding protections, and a safe restart mode.
How is the switching frequency of the device determined or adjusted?
The oscillator frequency can be adjusted using external components R, C, providing a range of 10–200 kHz.
What happens during the startup sequence (power-up)?
It starts switching as soon as the voltage on pin V passes the threshold level. Supply is then taken over by the auxiliary winding.
