NXP's SSL4120 Greenchip solution, combining a PFC and an HBC, delivers high efficiency (>93%), low THD (<10%), and high PF (>0.97) in high-power LED applications from 75 to 400 W.
Single chip with integrated controllers for PFC and half-bridge resonant converter
Designed for hi-power LED applications: 75 to 400 W
True universal mains operation from 90 to 305 V
Low THD (<10%) and high PF (>0.97)
Resonant topology and valley/zero voltage switching enable high efficiency (>93%)
Typical PFC frequency of 380 kHz enable compliance with regulatory requirements for THD
Compact form factor enables cost-effective designs with minimal external components
PFC in boundary-mode operation with on-time control
HBC burst mode switching
All-around protection, including OverCurrent Protection (OCP), OverVoltage Protection (OVP), demagnetization sensing, open-loop protection, capacitive mode protection, and a general-purpose latched protection input, enables safe operation under severe practical conditions
High-power LED Applications such as office lighting, shop lighting, high-bay and low-bay lighting, parking garage lighting, area lighting and street lighting.
