Richtek RT9206GS

Синхронный понижающий (Buck) (1), линейный (LDO) (2)3Контроллер4,75 В ~ 28 В

Overview

The RT9206GS 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.RT9206GS 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.
