3A High Performance Step-Up DC-DC Converter

RT9297

Update Alert Share

The RT9297 includes a high performance step-up DC-DC converter that provides a regulated supply voltage for active-matrix thin-film transistor (TFT) liquid-crystal displays (LCDs).

The Boost Converter incorporates current mode, fixed-frequency, 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.
