SSL1523A
SMPS ICs for mains LED drivers
Rev. 1 — 25 April 2012
Product data sheet
1. General description
The SSL1523A is a Switched Mode Power Supply (SMPS) controller IC that operate
directly from the rectified universal AC mains. It is implemented in the high-voltage Easy
High Voltage Silicon-On-Insulator (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 start-up circuit that operates 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 SSL1523A can operate in applications with a power range of up to 15 W.
In the most basic applications, the SSL1523A act 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 SSL1523A
renders an efficient and low cost power supply system for mains LED drivers.
2. Features and benefits
