Description:
High efficiency low noise pfm step-up dc/dc converter.
* 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 500kHz to 2MHz operation frequency allows for smaller capacitor and inductor. Fault condition protection uses cycle
