General Description

The RTQ9297-QT 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, fixedfrequency,

pulse-width modulation (PWM) circuitry with

a built-in N-Channel power MOSFET to achieve high

efficiency and fast transient response.

The RTQ9297-QT is available in a WDFN -10SL 3x3

package.
