TCS5116B

30V 1.2A Step -Down Dimmable LED Driver

产品描述

The TCS5116B is step-down regulator for dimmable LED driver, which is designed in continuous current mode for driving the high-brightness LEDs from a wide input voltage of 8.0V to 30V. The TCS5116B employs a hysteretic control scheme to regulate LED current. Moreover, the control scheme provides optimal loop stabilization and avery quick response time. The TCS5116Bimplements PWM and analog dimming together on the EN/DIM pin. The TCS5116B includes under-voltage lockout and thermal overload protection to prevent damage in the event of an output overload.

The TCS5116B requires a minimal number of readily available, external components and is available in a space saving SOT89-5 package.
