At the Input reflected-ripple current is measured with a inductor point of current-limit inception, the unit shifts from voltage Lin (4.7uH) and Cin (220uF, ESR < 1.0[ at 100 KHz) to control to current control. The unit operates normally once the simulate source impedance. output current is brought back into its specified range. Capacitor Cin, offsets possible battery impedance. Current ripple is measured at the input terminals of the module, measurement bandwidth is 0-500 KHz. Input Source Impedance The power module should be connected to a low To Oscilloscope ac-impedance input source. Highly inductive source +Vin +Out impedances can affect the stability of the power module. In applications where power is supplied over long lines and + + Lin DC / DC Current Load output loading is high, it may be necessary to use a capacitor Converter Probe at the input to ensure startup. Battery Cin -Vin -Out 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 8.2uF for the 5V input devices, a 3.3uF for Peak-to-Peak Output Noise Measurement Test the 12V input devices and a 1.5uF for the 24V devices. Use a Cout 0.47uF ceramic capacitor. Scope measurement should be made by using a BNC + +Vin +Out socket, measurement bandwidth is 0-20 MHz. Position the + load between 50 mm and 75 mm from the DC/DC Converter.
