Thermal Design Considerations Part 5 Design Considerations 5.
• • Measure the thermal resistance from the junction to where the leads are attached to the case. This definition is approximately equal to a junction to board thermal resistance. Use the value obtained by the equation (TJ – TT)/PD where TT is the temperature of the package case determined by a thermocouple. The thermal characterization parameter is measured per JESD51-2 specification using a 40-gauge type T thermocouple epoxied to the top center of the package case.
Electrical Design Considerations • • • • Ensure that capacitor leads and associated printed circuit traces that connect to the chip VDD and VSS pins are less than 0.5 inch per capacitor lead. Bypass the VDD and VSS layers of the PCB with approximately 100 μF, preferably with a high-grade capacitor such as a tantalum capacitor. Because the controller’s output signals have fast rise and fall times, PCB trace lengths should be minimal.
