TOSHIBA CD-MOS Integrated Circuit Silicon Monolithic

TC62D902FG

Offline Isolated AC/DC Flyback LED Controller built-in PFC

1. Overview

This product is an isolation type flyback mode LED

controller.

This device is controlling an average LED current from the

primary side current value and the bias side impulse-wave

of the transformer and the detection circuit of the

secondary side is unnecessary.

Then, this product has the active PFC function of the single

stage mode and the active bleeder pin to do triac dimmer

and realizes LED lighting with few components.

2. Application

Isolated AC/DC LED lighting
