BL8548, Variable Frequency Step-up DC/DC Converter

BL8548 Max.
3MHz, Variable Frequency Step-up DC/DC Converter DESCRIPTION The BL8548 variable frequency step-up Converter drives white LEDs with a con

Features

* allowing series connection of the white LEDs so that the LED currents are identical for uniform brightness. An enable input can be pulsed repeatedly to adjust LEDs brightness. The fast 3MHz operation frequency allows for smaller capacitor and inductor. Fault condition protection uses cycle-by cycle
