BP5872 isolated high power LED driver module

Overview | Key Feature 1 | Key Feature 2 | Key Feature 3 | Key Feature 4 | Electrical Characteristics | External Dimensions | Lineup | Applications Overview ROHM developed a thinner, isolated high power LED driver than its standard BP5870 and added dimming support, enabling compatibility with a wider range of lighting devices. Additional features include universal input and high efficiency operation, making it possible to easily add value to LED lighting applications of all types. Key Feature 1 : Thinner form factor results in greater versatility LEDs tend to be much thinner than conventional lighting products. ROHM LED drivers feature a thickness of only 15mm – 30% thinner than existing configurations – making them ideally suited for compact LED devices. Key Feature 2 : Dimming possible via analog input Dimming over a wide range (10-100%) is easily enabled using analog input. Key Feature 3 : PFC circuit built in for a power factor of 0.99 Power factor is heavily influenced by the resistance loss through the transformer windings and supply lines. The BP5872 features an active filter method with built-in PFC circuit that increases the power factor to 0.99, enabling support for high frequencies as well as compliance with IEC61000-3-2. Key Feature 4 : Pseudo-resonance method utilized for 83% efficiency A low noise, high efficiency pseudo-resonance switching method is used that minimizes switching loss across the switching MOSFET for improved efficiency.
