RT9292 : 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 lowcost and small output capacitors. The LED current is initially set by the external sense resistor (RSET), and the feedback voltage for the RT9292 series will .
RT9293 : Features The RT9293 is a high frequency, asynchronous boost converter. The internal MOSFET can support up to 10 White LEDs for backlighting and OLED power application, and the internal soft start function can reduce the inrush current. The device operates with 1-MHz fixed switching frequency to allow small external components and to simplify possible EMI problems. For the protection, the RT9293A provides 50V OVP and the RT9293B provides 50V/20V OVP to allow inexpensive and small-output capacitors with lower voltage ratings. The LED current is initially set with the external sense resistor RSET. The RT9293 is available in the tiny package type TSOT-23-6 and WDFN-8L 2x2 packages to provide t.
RT9297 : The RT9297 includes a high performance step-up DC-DC converter that provides a regulated supply voltage for activematrix thin-film transistor (TFT) liquid-crystal displays (LCDs). The Boost Converter incorporates current mode, fixedfrequency, pulse-width modulation (PWM) circuitry with a built-in N-Channel power MOSFET to achieve high efficiency and fast transient response. The RT9297 is available in a WDFN -10L 3x3 package.
