描述
The iW3627 is a digital offline PWM controller that provides a constant voltage for smart LED lighting applications and general-purpose power supplies up to 90W with power factor (PF >0.9) and low THD (<20%). It supports the most common single-stage isolated and non-isolated topologies (buck, buck-boost, or flyback) as a front-end or standalone power supply in solid-state lighting (SSL) applications with advanced digital control technology.
The iW3627 is compatible with Transphorm GaN technology and is ideal for applications requiring high efficiency and power factor correction (PFC).
