Current is measured at the input of the module. Figure 17: Input reflected-ripple test setup Vo GND COPPER STRIP 10uF tantalum 1uF ceramic SCOPE Resistive Load Note: Use a 10µF tantalum and 1µF capacitor. Scope measurement should be made using a BNC connector.

When the module is not soldered (via socket), place Kelvin connections at module terminals to avoid measurement errors due to contact resistance. % 100 ) ( × × × = Ii Vi Io Vo η DESIGN CONSIDERATIONS Input Source Impedance To maintain low-noise and ripple at the input voltage, it is critical to use low ESR capacitors at the input to the module. Figure 20 shows the input ripple voltage (mVp-p) for various output models using 6x47uF low ESR tantalum capacitors (SANYO P/N:16TQC47M, 47uF/16V or equivalent) and 6x22 uF very low ESR ceramic capacitors (TDK P/N:C3225X7S1C226MT, 22uF/16V or equivalent). The input capacitance should be able to handle an AC ripple current of at least: Figure 20: Input ripple voltage for various output models, Io = 16A (Cin = 6x47uF tantalum capacitors and 6x22uF ceramic capacitors at the input) 0 50 100 150 200 250 300 350 01 2 3 4 5 6 OutputVoltage(Vdc) Tantalum Ceramic Arms Vin Vout Vin Vout Iout Irms ⎟ ⎠ ⎞ ⎜ ⎝ ⎛ − = 1 |
