Краткое описание:
30V, 500mA Switch Boost Converter for White LED Applications
Дополнительная информация
The TPS61042 is a high-frequency boost converter with constant current output designed to drive white LEDs. It features an internal 30V MOSFET switch and operates from an input voltage range of 1.8V to 6V. The LED current is set via an external sense resistor and regulated at 252mV. The device supports brightness control through PWM or analog signals and includes integrated overvoltage protection and load disconnect during shutdown to prevent leakage current.
