The RT8458 is a PWM controller with an integrated high
side floaTIng gate driver. It is used for step down converters
by well controlling the external MOSFET and regulaTIng a
constant output current. The output duty cycle of the
RT8458 can be up to 100% for wider input voltage
applicaTIon, such as E27 and PAR30 off-line LED lighTIng
products.
