Description: CMOS Boost Converter - White LED Driver

Features

* Drives up to 5 White LEDs from 3V Power Efficiency up to 87% Low Quiescent Ground Current 0.1mA Adjustable Output Current (up to 30mA) High Frequency 1MHz Operation “Zero” current

Applications

* LED dimming can be done by using a DC voltage, a logic signal, or a pulse width modulation (PWM) signal. The shutdown control pin allows the device to be placed in power-down mode with “zero” quiescent current. In addition to thermal protection and overload current limiting, the device also enters
