RT9293

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 .

RT9296 : Features The RT9296 is a synchronous boost converter, which is based on a fixed frequency pulse-width-modulation (PWM) controller using a synchronous rectifier to obtain maximum efficiency. The converter provides a power supply solution for products powered by a variety of batteries such as single cell, dual cell alkaline, NiMH and NiCd battery. At light load currents, the converter enters the power save mode to maintain a high efficiency over a wide load current range. The output voltage can be programmed by an external resistor divider, or be a fixed voltage. Moreover, the converter can be disabled to the minimize battery drain. During shutdown, the load is completely disconnected from 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.
