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. The RT4809 is an optimized design for wide output voltage range applications.
