The OB3635BMP LED Drivers SOT23-6 RoHS are manufactured by On-Bright and are a low-frequency converter step up converter with a wide input voltage range of 4.5V to 36V. It is designed to drive high-current single-cell Li-ion and 2-cell alkaline batteries. It features a high switching frequency of 1MHz, which helps reduce electromagnetic interference. It also features high efficiency, low quiescent current, and low standby current, making it an ideal choice for portable and handheld applications. The device includes additional protection features such as thermal shutdown, current inrush limit, and over voltage protection. The SOT23-6 RoHS package allows for easy board layout with minimal external components.
