Body Electronics Infotainment Portable Navigation Powertrain Safety and Control Vehicle Safety Reliable Integrated Smart High-End Switches Save Space The reliable and safe conversion of high currents to ground resistive or inductive loads is a must for designers of automotive applications. Fairchild has developed a family of smart high-end switches specifically for advanced electrical loads that do not rely on discrete mosfet solutions. Reduced component count and PCB complexity, and better system reliability by integrating protection and diagnostic functions. The series includes FDDS100H06 U F085 smart high-side switch, n-channel power mosfet with charge pump, ground referenced cmo compatible input and diagnostic output, with integrated protection. The family also features smart high-side switches, including an n-channel power mosfet device with charge pump, current control input and diagnostic feedback load current sensing and integrated smart trench chip technology.

Achieving Highest Power Density, Efficiency Power Supply Design The challenge of delivering higher power density and efficiency in fewer boards goes hand in hand with the growing demand for high-density embedded DC-DC power capabilities. The solution to this dilemma, Fairchild's FDPC8011S, has been developed at higher switching frequencies, including dual packaging. The switch nodes are internally connected to synchronize the placement and routing of the buck converters. Control mosfet (Q1) and Synchronous Syncfet 8482 ; (Q2) designed for optimum power efficiency. The FDPC8011S includes 1.4MΩ synchronous FET technology and 5.4MΩ control, a low-performance n-channel mosfet integrated in an all-clamp package that helps reduce capacitor count and inductor size. The device's power supply fails, and the low side allows for easy placement and routing, enabling board layout and achieving optimal thermal performance.

High Voltage Insulation Reliability Small Size Achieves Reliability, High Insulation Voltage and High Noise Immunity High Power Industrial Applications with Fairchild FOD8320 and FOD8321, Advanced 2.5A Current Output Gate Driver Optocoupler. Using Fairchild's OptoPlanar® packaging technology and optimized IC design, both devices are packaged in a wide-body 5-pin small outline package. The FoD8320 offers a compact footprint while allowing creepage and clearance distances greater than 10mm, with an internal insulation distance of 0.5mm. The FOD8321 does not require 10mm creepage and clearance distances, but requires a small form factor. Both devices offer an extended industrial temperature range (-40°C to 100°C) and are ideal for fast switching power IGBTs and mosfets for industrial inverters.

Minimizing Components for Higher Power Conversion Efficiency SMPS designers face several complex design issues: space constraints, and the need for energy-efficient cost-effective power solutions that optimize system performance and improve reliability. Fairchild now offers a solution: the fsl206mr integrated pulse width modulator (pwm) controller. By integrating protection circuits, the controller improves the reliability of the switching power supply and saves board space. Part of the Green Mode Fairchild Power Switch (FPS™) family of devices, the integrated pwm controller with avalanche rugged sensor includes an internal regulator and eliminates the need for an auxiliary bias winding. The highly integrated PWM controller includes a built-in, high voltage start-up and full protection circuit that saves board space and total bill of materials (BOM) cost. Optimized When the input voltage is 265vac, the power loss of the device can reach 150mw without biasing the winding with bias winding and 30mw at no load.
