RT8509A - Richtek

RT8509A Step-Up DC/DC Converter

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). The RT8509A incorporates current mode, fixed-frequency, pulse width modulation (PWM) circuitry with a built in N-MOSFET to achieve high efficiency and fast transient response. The RT.

Features

include adjustable soft-start, over-voltage protection, and over-temperature protection. The RT8509A is available in the WDFN-12L 5x5 package. Marking Information RT8509A GQW YMDNN RT8509AGQW : Product Number YMDNN : Date Code Features
