Controller IC Chip - RT8105GS Chip for laptop- Integrated portable calculator chip(SKU.1-CHIP0925)
The RT8105 is a high efficiency synchronous buck PWMcontrollers that generate logic-supply voltages in PC basedsystems. These high performance , single output devicesinclude internal soft-start, frequency compensationnetworks and integrates all of the control, outputadjustment, monitoring and protection functions into asingle package.The device operating at fixed 300kHz frequency providesan optimum compromise between efficiency, externalcomponent size, and cost.Adjustable over-current protection (OCP) monitors thevoltage drop across the RDS(ON)of the lower MOSFET forsynchronous buck PWM DC/DC controller. The over-current function cycles the soft-start in 4-times hiccupmode to provide fault protection, and in an always hiccupmode for under-voltage protection.
