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. Tiny package type TSOT-23-6 and
WDFN-8L 2x2 packages provide the best solution for PCB
space saving and total BOM cost.RT9285APQW RT9285BPQW RT9285AGQW RT9285BGQW RT9285APJ6 RT9285BPJ6 RT9285AGJ6 RT9285BGJ6资料下载
