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).
特性
- 100W+ output power with enhanced internal MOSFET driver
- Supports isolated or non-isolated topologies including flyback, buck, or buck-boost
- High PF (>0.9) and low THD (<20%)
- Adaptive output voltage transient detection
- Enables fast transient response with variation < ±10% of nominal output voltage
- Accommodates large capacitance variations and capacitor aging configurable minimum switching frequency
- Enables low no-load standby power consumption (<200mW)
- Configurable PWM maximum switching frequency
- Optimizes for high efficiency, small size
- Active start-up – Reduces turn-on time without increasing standby power
- Tiny 6-pin SOT-23 package
- Fully protected
- Input brown-out protection
- Over-temperature protection
- Output overvoltage, overcurrent, and overload protection
