RT9367A

Pinout




Description

The RT9367A is an integrated solution for backlighting and phone camera input supply. The part contains a charge pump white LED driver and dual low dropout linear regulators.
In the section of charge pump, The RT9367A can power up 4 white LEDs with regulated constant current for uniform intensity. Each channel (LED1-LED4) can support up to 25mA. The part maintains highest efficiency by utilizing a 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-step of LED current by I²C interface.
In the section of linear regulator, The RT9367A comprises a dual channel, low noise, and low dropout regulator sourcing up to 300mA at each channel. The range of output voltage can be configured from 1.1V to 3.3V by I²C interface. The outputs of LDO offer 3% accuracy and low dropout voltage of 250mV @ 300mA. The LDO also provides current limiting and output short circuit thermal folded back protection.
