Technical specification sheet for the Belling BL8532 PFM DC/DC boost converter designed for LED applications with adjustable current or voltage output.
The Belling BL8532 is a PFM control mode open-type DC/DC boost constant current board designed for LED applications. It features an internal over-voltage protection module to prevent damage to the board and external circuits under open load or no-load conditions. The device can provide constant current to single, parallel, or series-connected LEDs, or constant voltage adjustable between 2.5V and 6.0V via an external resistor.
The datasheet provides detailed technical specifications, application circuits for constant current and constant voltage modes, and guidelines for selecting external components such as inductors, capacitors, and Schottky diodes. It includes performance characteristics, efficiency curves, and test circuit diagrams to assist in design and verification. This manual is written in Chinese.
