5. Main Features and Functions 5.1 Operating Temperature RangeThe MAA11 series converters can be operated by a wide ambient temperature range from -40°C to 85°C. The standard model has aplastic case and case temperature can not over 100°C at normal operating. 5.2 Output Short Circuit ProtectionAll different voltage models have a momentary short-circuit protection (1 Second maximum). Please notice this condition and avoidoutput short as much as possible.

6. Applications 6.1 Recommended Layout PCB FootprintThe system designer or the end user must ensure that other components and metal in the vicinity of the converter meet the spacing requirements to which the system is approved. Low resistance and low inductance PCB layout traces are the norm and should be used where possible. Due consideration must also be given to proper low impedance tracks between power module, input and output grounds. The recommended footprints and soldering profiles are shown as Figure 3.Note:

6.4 Input Capacitance at the Power ModuleThe converters must be connected to low AC source impedance. To avoid problems with loop stability source inductance should be low. Also, the input capacitors (Cin) should be placed close to the converter input pins to de-couple distribution inductance. However, the external input capacitors are chosen for suitable ripple handling capability. The input capacitors (Cin) is recommended by low ESR capacitors of 2.2uF for all models. Testing Circuit for reflected ripple current as shown in Figure 5represents typical measurement methods. C1 and L1 simulate a typical DC source impedance. The input reflected-ripple current is measured by current probe to oscilloscope with a simulated source Inductance (L1).

L1 : 12uFC1: 2.2uF Tantalum capacitorCin: NoneFigure 5 Input Reflected-Ripple Test Setup

6.5 Test Set-UpThe basic test set-up to measure parameters such as efficiency and load regulation is shown in Figure6 and 7. When testing the modules under any transient conditions please ensure that the transient response of the source is sufficient to power the equipment under test. We can calculate the· Efficiency· Load regulation and line regulation.The value of efficiency is defined as:

Where:Vo is output voltage, Io is output current, Vin is input voltage, Iin is input current.

The value of load regulation is defined as:

Where:VFL is the output voltage at full load VNL is the output voltage at 20% load

The value of line regulation is defined as:

Where: VHL is the output voltage of maximum input voltage at full load. VLL is the output voltage of nominal input voltage at full load.

6.6 Output Ripple and Noise MeasurementThe test set-up for noise and ripple measurements is shown in Figure8 and 9. A coaxial cable was used to prevent impedance mismatch reflections disturbing the noise readings at higher frequencies. Measurements are taken with output appropriately loaded and all ripple/noise specifications are from D.C. to 20MHz Band Width. The output ripple/noise is measured with 0.33uF ceramic capacitor across output. The ripple and noise is measured by BNC at 50mm to 75mm (2” to 3”) from the module.

6.7 Output CapacitanceThe MAA11 series converters provide unconditional stability with or without external capacitors. For good transient response low ESR output capacitors should be located close to the point of load. These series converters are designed to work with load capacitance to see technical specifications.

7. Safety & EMC

7.1 Input Fusing and Safety ConsiderationsThe MAA11 series converters have not an internal fuse. However, to achieve maximum safety and system protection, always use an input line fuse. We recommended a time delay fuse 0.5A for all models. Figure10 circuit is recommended by a Transient Voltage Suppressor diode across the input terminal to protect the unit against surge or spike voltage and input reverse voltage.
