Preliminary RT9287A Boost Converter for WLED Power with Dual LDO General Description The RT9287A is an integrated solution for WLED and camera power. It contains a boost converter with internal schottky diode to provide WLED power and Dual LDO for the power of camera image sensor. In the section of boost converter, RT9287A's optimized operation frequency can meet the requirement of small LC filters value and low operation current with high efficiency. Internal soft start function can reduce the inrush current. The initial current of WLED is set by the external resistor RSET. The feedback voltage is 250mV. z Features z Boost Converter `VIN Operating Range : 2.7V to 5.
