Overview
® RT8509A 4.
5A Step-Up DC/DC Converter General Description 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 RT8509A has 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, ...
