NXP exhibited two GreenChip products, SSL4120 and SSL4101T, at the Guangzhou Lighting Fair this week. Among them, the SSL4120 GreenChip half-bridge resonant controller is NXP's latest high-power LED driver chip, which can support up to 400W high-power LED applications, fully supporting commercial applications, and supporting high efficiency directly from the rectified universal commercial voltage from 90 to 305 volts. start up. SSL4101T is a multi-chip component (MCM), which contains two chips. With power requirements ranging from 10W to 300W, the SSL4101T makes the design of efficient and reliable power supplies for LED lighting applications easy to implement and requires only a minimum number of external components. Both NXP LED driver chips support office lighting, shopping mall lighting, high bay and parking lot lighting, square lighting and street lighting.
The main features of SSL4120 include:
· Single chip integrated PFC and half-bridge resonant converter (HBC) controller
· Designed for high power LED applications from 75 to 400 W
· Real utility operation from 90 to 305 V
· Low THD (? 10%) and high PF (? 0.97)
· Resonant topology and valley / zero voltage switching to achieve high performance (》 93%)
· 380 kHz typical PFC frequency meets THD laws and regulations
· Compact form factor enables the most efficient design with minimal external components
· PFC is in a critical working mode that can be controlled in real time
· HBC burst switch
· All-round protection, including over-current protection (OCP), over-voltage protection (OVP), demagnetization detection, open circuit protection, capacitive mode protection and general lockout protection input, even in harsh operating conditions, can ensure safe work.
The new SSL4101T enables the traditional 150W LED lighting application power supply (wide voltage input, 48V (DC) output, TEA1761T secondary side synchronous rectification) to achieve the following performance at full load:
· 120 V (AC): 92% efficiency, 0.998 power factor, 4.7% total harmonic distortion, "175 mW standby power
· 277 V (AC): 94% efficiency, 0.988 power factor, 8.5% total harmonic distortion, "390 mW standby power
NXP exhibited SSL4120 and SSL4101T GreenChip products at the Guangzhou International Lighting Exhibition this week. SSL4120 and SSL4101T are currently in mass production. You can visit the NXP website to learn more about these two products: SLL4120 and SSL4101T.
