Toshiba TB62D Constant Current LED Drivers

Toshiba TB62D Constant Current LED Drivers incorporate 7-bit PWM dimming controllers and constant current drivers and are designed for LED/LED illumination. The TB62D LED drivers feature output current circuits divided into three blocks, and a relevant external resistor adjusts the output current. These LED drivers can be set to 64 ID recognition addresses with the ID setting pin.

Toshiba TB62D901FNG LED Lighting Driver is a constant current driver IC ideal for step-down AC/DC conversion type LED lighting applications. This LED driver features an architecture with automatic off-time adjustment control that can achieve minimum LED current variations. The TB62D901FNG LED lighting driver allows linear dimming or PWM dimming and offers extensive detection functions. These functions include thermal shutdown, over-current detection, over-voltage detection, under-voltage lockout, and a current sensing input terminal open detection.
