BP3309 Description

Short technical summary and product information.

The BP3309 from BPS is a high-precision primary-side regulation isolated flyback controller. It is specifically designed for offline constant current LED lighting applications.

 

This controller integrates a single-stage Active Power Factor Correction (APFC) circuit, operating in critical conduction mode. This design choice helps achieve a high power factor and reduces switching losses in the power MOSFET. The BP3309 utilizes a patented compensation method to deliver excellent line regulation, with the flexibility for external tuning.

 

Key features include its primary-side regulation, isolated flyback topology, and on-chip PFC circuit. It is suitable for applications requiring efficient and stable LED driving.

 

This component is classified under LED Drivers within the Power Management PMIC category.
