Краткое описание:
Constant Current LED Driver with 18-V Overvoltage Protection
Дополнительная информация
The TPS61043 is a high-frequency boost converter with constant current output designed to drive white LEDs. It operates with an input voltage range of 1.8 V to 6 V and includes an internal 30-V switch. The device features an integrated overvoltage protection that limits the output to typically 18 V and a control pin that allows for precise PWM brightness control (100 Hz to 50 kHz) while also providing a load disconnect function during shutdown to prevent leakage current.
