General Description
The RT4841 is Synchronous Boost Converter with output
isolation MOS for active matrix thin film transistor (TFT)
liquid crystal displays (LCDs).
The Device incorporates current mode, fixed-frequency,
pulse width modulation (PWM) circuitry and fully integrated
synchronous boost converter with a 80mΩ power switch
and a 80mΩ rectifier switch to achieve high efficiency,
small size and fast transient response in TFT-LCD
applications. Moreover, Device contains one ISO MOSFET
controller for power on sequence of step-up converter. The
RT4841 has a wide input voltage range from 8.6V to 15.9V
and device has 5A (min.) switching current capability. The
RT4841 is available in a WQFN-20L 4x4 package.
