Tiny Package, High Performance, Diode Embedded White LED Driver
General Description
Features
The RT9285 is a high frequency asynchronous boost converter with internal diode, which can support 2 to 5 White LEDs for backlighting and OLED power supply.
The Internal soft start function can reduce the inrush current.
The device operates with 1MHz fixed switching frequency to allow small external components and to simplify possible EMI problems.
The device comes with 20V over voltage protection to allow inexpensive and small-output capacitors with lower voltage rating.
The LED current is initially set with the external sense resistor RSET, and the feedback voltage is 250mV.
