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 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 TEA1620P 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 TEA1620P renders an efficient and low cost power supply system.
The Philips TEA1620P is a Switched Mode Power Supply (SMPS) controller IC designed for general-purpose supplies. It operates directly from rectified universal mains and is implemented in a high voltage EZ-HV SOI process combined with a low voltage BICMOS process. The device includes an integrated 48 and 650 V power switch and a dedicated circuit for valley switching to ensure efficiency in slim-line electronic power-plug concepts.

The TEA1620P is suitable for chargers, adapters, TV and monitor standby supplies, and PC peripherals.
The maximum duty factor is set to 75% at a typical oscillation frequency of 100 kHz.
When the junction temperature exceeds the thermal shutdown temperature, the IC stops switching and lowers its current to the start-up current.
