Preliminary RT9287 Boost Converter for OLED Power with Dual LDO General Description The RT9287 integrates a boost converter for OLED power and a Dual LDO for camera image sensor power. To achieve high efficiency, the boost converter optimizes its operating frequency for small LC filters value and reduces the operating current. Moreover, the internal soft-start function reduces the inrush current. For the Dual LDO part, it possesses functions of 2% accuracy, dual channel, low dropout voltage (240mV@300mA), low noise, low ground current and low dropout regulator sourcing up to 300mA at each channel. For battery-powered devices, it provides near zero shutdown current.
