Controller IC Chip - RT8205AGQW RT8205A ( CJ=** ) QFN24 Chip for laptop - Ολοκληρωμένο τσιπ φορητού υπολογιστή (Κωδ.1-CHIP0944) The RT8205A/B/C dual step-down, switch-mode power-supply  controller  generates  logic-supply  voltages  inbattery-powered systems. The RT8205A/B/C includes twopulse-width  modulation  (PWM)  controllers  fixed  at  5V/3.3V or adjustable from 2V to 5.5V. An alternative LGATE1output LG1_CP can be used for external charge pump(RT8205B). And an optional external charge pump can bemonitored through SECFB (RT8205C). This device alsofeatures 2 linear regulators providing fixed 5V and 3.3Voutputs. The linear regulator each provides up to 70mAoutput current with automatic linear-regulator bootstrappingto the PWM outputs. The RT8205A/B/C includes on-boardpower-up sequencing, the power-good output, internal soft-start,  and  internal  soft-discharge  output  that  preventsnegative voltages on shutdown.A constant on-time PWM control scheme operates withoutsense  resistor
