The SI-8105QL is a step-down switching regulator IC, designed as an output voltage regulator at the secondary stage of switch mode power supplies. The current-mode control system permits small ceramic capacitors to be used as output capacitors. Together with the compact DIP8 package, this allows reduction of regulator circuitry area on the PCB by approximately 50% in comparison with conventional topologies.
Designed to save power, losses in the SI-8105QL are reduced by controlling the maximum on-resistance of a built-in output MOSFET to as low as 165 mΩ. Furthermore, die miniaturization has been accomplished through a proprietary BCD process.
The SI-8105QL supplies an output current of 3.5 A and an output voltage that is variable from 0.5 to 24 V, which is set simply to a voltage compatible with the diverse reduced power supply voltages required by signal processing ICs. Accepting a wide input voltage range, from 4.75 to 28 V, the SI-8105QL can be driven directly by a 24 V power supply.
Applications include power supplies for signal processing ICs for memories and microcomputers used in plasma display panel (PDP) TVs, liquid crystal display (LCD) TVs, computer hard drives, and DVD recorders.
