General description
The SSL1623PH 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 (Easy High Voltage Silicon-On-Insulator) process, combined with a low voltage BiCMOS (Bipolar Complementary Metal Oxide Semiconductor) 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 LED driver concept possible.
The SSL1623PH can operate in LED applications with a power range of up to 25 W. The SSL152x family would be a better choice if power below 15 W is required.
In its most basic version of application the SSL1623PH 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 SSL1623PH renders an efficient and low cost LED power supply system.
