简介
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).
特性
