General Description

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.
