RT8509A

4.5A Step-Up DC/DC Converter

General Description

Features

^90% Efficiency

The RT8509A is a high performance switching Boost

converter that provides a regulated supply voltage for active

matrix thin film transistor (TFT) liquid crystal displays

(LCDs).

^Adjustable Output Up to 24V

^2.8V to 14V Input Supply Voltage

^Input Supply Under-Voltage Lockout

^Fixed 1.2MHz Switching Frequency

^Adjustable Soft-Start

The RT8509Aincorporates current mode, fixed-frequency,

pulse width modulation (PWM) circuitry with a built in

N-MOSFET to achieve high efficiency and fast transient

response.

^V_OUTOver-Voltage Protection

^Over-Temperature Protection

^Thin 12-Lead WDFN Package

^RoHS Compliant and Halogen Free

The RT8509Ahas a wide input voltage range from 2.8V to

14V. In addition, the output voltage can be adjusted up to

24V via an external resistive voltage divider. The maximum

peak current is limited to 4.5A (min.). Other features

include adjustable soft-start, over-voltage protection, and

over-temperature protection.

Applications

 GIPTFT-LCDPanels
