RT9363A
3 Channels 90mA x1/x2 Charge Pump White LED Driver
General Description
The RT9363A is a compact, high efficient and highly
integrated charge pump white LED driver. It maintains the
highest efficiency by utilizing a x1/x2 fractional charge
pump and low dropout current regulators. The RT9363A
supports up to 3 white LEDs and regulates a constant
current for uniform intensity. The part implements a 4-bit
DAC for brightness control. Users can select external RSET
or internal RSET by ISET pin. The dimming of white LEDs'
current can be achieved by applying a pulse signal to the
EN pin. There are totally 16 steps of current could be set
by users. The part can support 15mA to 30mA for the 100%
current setting. Users also can use the internal RSET for
100% current setting of 20mA just by connecting the ISET
pin to VIN. The operating voltage range is from 2.8V to
5.5V. Internal soft start circuitry effectively reduces the in-
rush current while both start-up and mode transition. The
load is disconnected from VIN while shutdown and the
shutdown current is less than 1uA.
RT9363A is available in a WDFN -10L 3x3 package.
