RT4809 Overview
The RT4809 is a DC-DC boost converter which is designed to provide the power of PWM controller. The RT4809 incorporates voltage mode, fixed-frequency, pulse width modulation (PWM) circuitry with a built in N-MOSFET to achieve high efficiency and fast transient response. The RT4809 input operating range is from 2.5V to 36V.
