Краткое описание:
500-mA, 65-V Common Anode Constant Current Buck LED Driver
Дополнительная информация
The TPS92511 is a PWM-controlled FET controller which is a step-down regulator for driving high-brightness LEDs. It can operate over a wide input voltage range of 4.5 V to 65 V and features an integrated low-side N-channel MOSFET. The device is designed to work in common anode applications without an external current sensing resistor, reducing component count. It supports analog dimming and thermal foldback, and its switching frequency is programmable from 50 kHz to 500 kHz.
