General description
The SSL152x 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, which makes a very efficient slim-line electronic concept for solid state lighting applications possible.
The SSL152x can operate in applications with a power range of up to 15 W. For a power range between 15 W and 25 W the SSL1623PH is the best choice. For LED powers above 25 W the SSL1750 can be used.
In its most basic applications, the SSL152x 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 SSL152x family renders an efficient and low cost power supply system for mains LED drivers.
