Page 8 - Soldering and Cleaning Considerations; DESIGN CONSIDERATIONS; Input Source Impedance

The input source must be insulated from the ac mains by reinforced or double insulation. The input terminals of the module are not operator accessible. If the metal baseplate is grounded , one Vi pin and one Vo pin shall also be grounded. A SELV reliability test is conducted on the system where the ...

Page 9 - FEATURES DESCRIPTIONS; Over-Voltage Protection; Vout

FEATURES DESCRIPTIONS Over-Current Protection The modules include an internal output over-current protection circuit, which will endure current limiting for an unlimited duration during output overload. If the output current exceeds the OCP set point, the modules will automatically shut down (hiccup...

FEATURES DESCRIPTIONS (CON.) Output Voltage Adjustment (TRIM) To increase or decrease the output voltage set point, the modules may be connected with an external resistor between the TRIM pin and either the SENSE(+) or SENSE(-). The TRIM pin should be left open if this feature is not used. Figure 18...

Page 11 - THERMAL CONSIDERATIONS; Thermal Testing Setup; Figure 20: Wind tunnel test setup; Thermal Derating; THERMAL CURVES

THERMAL CONSIDERATIONS Thermal management is an important part of the system design. To ensure proper, reliable operation, sufficient cooling of the power module is needed over the entire temperature range of the module. Convection cooling is usually the dominant mode of heat transfer. Hence, the ch...
