The RT9206 is a low cost, combo power controller, which
integrates a synchronous step-down voltage-mode PWM
and two HV linear controllers. Directly drive external
N-MOSFET makes it easy to implement a high efficiency
and cost attractive power solution. Voltage mode control
loop and constant operation frequency with external
compensation network provide better stability in wide
operation range. Adjustable operation frequency up to
600kHz can minimize the inductor size and PCB space. It
is particularly suitable in wide input voltage range (from
4.75V to 28V) and multi-output applications.
Linear controller features flexible linear power design.
Delivered power can be simply decided by external
N-MOSFET selection. Output voltage level is chosen via
external resistor divider. The 0.8V internal reference can
satisfy most of the applications. Under voltage lockout
provide cost effective protection of output.
RT9206 provides complete safety protection function: soft
start, over current protection, over voltage and under voltage
protection. Set current limit by choosing different MOSFET.
Synchronous Buck control mode provides excellent over
voltage protection by turning on low side MOSFET to
prevent any damage of end device from abnormal voltage
stress as over voltage condition occurs.
