BP5875 isolated high power LED driver module | New product new technology

Compact size supports a variety applications

Overview

ROHM’s new BP5875 is designed to be a more compact version of the BP5872, and features the same key advantages, including a thin form factor, dimming compatibility, harmonics standards compliance, universal input, and high efficiency operation, making it ideal for a variety of applications.

Key Feature 1 : Compact size compatible with a variety of applications

ROHM’s existing power supply module, the BP5872, proved too large to integrate into the power supply housings of ceiling lights.
In response, ROHM developed the BP5875, featuring a compact size compatible with ceiling light specifications while maintaining the same performance and characteristics.

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 resistance loss through the transformer windings and supply lines.
The BP5875 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.
