<div align="justify">The RT9385B is a 5 channel WLED driver with auto mode selection of x1, x1.5 and x2 mode with low dropout voltage in current sources. The RT9385B can power up to 5 white LEDs with regulated constant current for uniform intensity. Each channel (LED1 to LED5) can support up to 25mA. The part maintains highest efficiency by utilizing x1/x1.5/x2 fractional charge pump and low dropout current regulators. An internal 5-bit DAC is used for brightness control. Users can easily configure up to 32 steps of LED current by enable pin.<br />The RT9385B is available in a WQFN-16L 2x3 package. Small 1μF capacitors can be used for fly capacitors. It provides the best backlighting solution with high efficiency and smallest board space for portable application.</div>
