The iW3827 integrates a 650V power MOSFET with an advanced digital controller and offers configurable maximum and minimum switching frequencies to provide design flexibility in high PF solid-state lighting (SSL) constant voltage applications up to 8W. It supports the most common single-stage isolated and non-isolated configurations (buck, buck-boost or flyback) to create a front-end power supply for smart lighting applications. The iW3827 uses advanced, proprietary digital control technology to enable high power factor (PF >0.9) and low THD (<20%). The iW3827 offers configurable maximum PWM switching frequency to allow optimization between size and efficiency and configurable minimum PFM switching frequency to optimize between transient performance and low no-load power consumption. The unique digital control technology accommodates large output capacitor variations while enabling fast transient response to keep the transient output voltage within 10% of its nominal level.
