RT9292

Pinout




Description

The RT9292 is a high frequency and high efficiency asynchronous boost converter for WLED driving application. It integrates a 28V MOSFET to support up to 6 White LEDs for panel backlighting and OLED power applications. Besides, an internal soft start function is integrated to reduce the inrush current. Moreover, the device operates with 1MHz fixed switching frequency for the use of small external components and better EMI performance. For lower voltage application, the IC provides a 26V over voltage protection function for using the low-cost and small output capacitors. The LED current is initially set by the external sense resistor (R_SET), and the feedback voltage for the RT9292 series will be 104mV and 330mV respectively. The RT9292 is available in TSOT-23-6 and WDFN-8L 2x2 tiny packages to achieve best solution for PCB space and total BOM cost saving considerations.
