RTQ9297 Overview
Description
The RTQ9297 includes a high performance step-up DCDC 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.
Key Features
