Controller IC Chip - TPS51020DBT TPS51020 PS51020 TSSOP 30 for laptop - Ολοκληρωμένο τσιπ φορητού υπολογιστή (Κωδ.1-CHIP1127) The TPS51020 is a multi-function dualsynchronous step-down controller for notebook system power. The part is specifically designed for high performance, high efficiency applications where the loss associated with a current sense resistor is unacceptable. The TPS51020 utilizes feed forward voltage mode control to attain high efficiency without sacrificing line response. Efficiency at light load conditions can be maintained high as well by incorporating autoskip operation. A selectable, Suspend to RAM (STR) supported, DDR option provides a one chip solution for all switching applications from 5-V/3.3-V supply to a complete DDR termination solution. Wide Input Voltage Range: 4.5-V to 28-V Selectable Dual and DDR Modes Selectable Fixed Frequency Voltage Mode Advanced Power Good Logic Monitors both Channels Selectable Autoskip Mode Integrated Boot Strap Dio
