Highly inductive source impedances can affect the stability of the power module. Input reflected-ripple current is measured with a inductor Lin (4.7uH) and Cin (220uF, ESR < 1.0[ at 100 KHz) to simulate source impedance. Capacitor Cin, offsets possible battery impedance. Current ripple is measured at the input terminals of the module, measurement bandwidth is 0-500 KHz. To Oscilloscope + + Battery +Vin Lin DC / DC Converter Current Probe Cin +Out -Vin Load In applications where power is supplied over long lines and output loading is high, it may be necessary to use a capacitor at the input to ensure startup. Capacitor mounted close to the power module helps ensure stability of the unit, it is recommended to use a good quality low Equivalent Series Resistance (ESR < 1.0[ at 100 KHz) capacitor of a 2.2uF for the 5V input devices, a 1.0uF for the 12V input devices and a 0.47uF for the 24V input devices. -Out + DC Power Source Peak-to-Peak Output Noise Measurement Test +Vin + +Out DC / DC Converter Load Cin - -Vin -Out Use a Cout 0.33uF ceramic capacitor.
