Controller IC Chip - RT8205BG QFN-24 chip for laptop - Ολοκληρωμένο τσιπ φορητού υπολογιστή (Κωδ.1-CHIP0154) The RT8205 is a dual step-down, switch mode powersupply controller generating logic-supply voltages inbattery powered systems. It includes two Pulse-WidthModulation (PWM) controllers adjustable from 2V to 5.5V,and also features fixed 5V/3.3V linear regulators. Eachlinear regulator provides up to 100mA output current withautomatic linear regulator bootstrapping to the PWMoutputs. An optional external charge pump can bemonitored through SECFB (RT8205M). The RT8205 includes on-board power up sequencing, a power goodoutput, internal soft-start, and internal soft-dischargeoutput that prevents negative voltage during shutdown.The constant on-time PWM control scheme operateswithout sense resistors and provides 100ns response toload transient response while maintaining nearly constantswitching frequency. To eliminate noise in audioapplications, an ultrasonic mode is included, whichmaint
