NXP SSL4101 GreenChip III+开关电源解决方案

NXP公司的SSL4101是第三代 GreenChip III+绿色开关电源(SMPS)控制器,包括PFC控制器和反激控制器,通用电压70 V (AC)到305 V (AC)输入,只需很少数量的外接元件就能构成低成本的LED照明电源,主要用在LED照明以及10W-300W的开关电源.本文介绍了SSL4101主要特性和优势,方框图,典型应用配置图以及SSL4101驱动板指标, 48V/150W SSL4101演示板电路图和材料清单.

The GreenChip III+ is the third generation of green Switched Mode Power Supply (SMPS) controller ICs. The SSL4101T combines a controller for Power Factor Correction (PFC) and a flyback controller. Its high level of integration allows the design of a cost-effective LED lighting application power supply with a very low number of external components.

The special built-in green functions provide high efficiency at all power levels. This applies to quasi-resonant operation at high power levels, quasi-resonant operation with valley skipping, as well as to reduced frequency operation at lower power levels. At low power levels, the PFC switches off to maintain high efficiency.
