Краткое описание:
1A Step-Down Constant Current High Efficiency LED Driver
Дополнительная информация
The PAM2804 is a step-down buck DC-DC converter designed to drive high-power LEDs with a constant current of up to 1A. It operates from an input voltage range of 2.5V to 6V, making it suitable for single Li-ion cells or 3-4 AA batteries. The device features a low 0.1V feedback voltage to maximize efficiency, reaching up to 93%. It includes an internal power switch and synchronous rectifier to reduce external component count. Additional features include undervoltage lockout, over-temperature shutdown, and short/open LED protection.
