Test Setup Input ReflectedRipple Current Test Setup Input reflectedripple current is measured with a inductor Lin (4.7μH) and Cin (2μF, ESR < 1.0Ω at 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 0500 KHz. To Oscilloscope Lin Battery Cin Current Probe PeaktoPeak Output Noise Measurement Test Use a 4.7μF ceramic capacitor. measurement should be made by using a BNC socket, measurement bandwidth is 0 MHz. Position the load between 50 mm and 75 mm from the DC/DC. Single Output Technical Notes Overload Protection To provide hiccup mode protection in a fault (output overload) condition, the unit is equipped with internal current limiting circuitry and can endure overload for an unlimited duration. Overvoltage Protection The output overvoltage clamp consists of control circuitry, which is independent of the primary regulation loop, that monitors the voltage on the output terminals. The control loop of the clamp has a higher voltage set point than the primary loop. This provides a redundant voltage control that reduces the risk of output overvoltage. The OVP level can be found in the output data. Input Impedance The power module should be connected to a low acimpedance input source. Highly inductive source impedances can affect the stability of the power module. In applications where power is supplied over long lines and output loading is high, it may be necessary to use a capacitor on the input to insure startup. By using a good quality low Equivalent Series Resistance (ESR < 1.0Ω at khz) capacitor of a 10μF for the 12V input devices and a 4.7μF for the 24V input devices and a 2.2μF for the 48V devices, capacitor mounted close to the power module helps ensure stability of the unit. Output Ripple Reduction Cin Resistive A good quality low ESR capacitor placed as close as practicable across the load will give the best ripple and noise performance. To reduce output ripple, it is recommended to use 4.7μF capacitors at the output. Dual Output Com. Resistive Single Output Dual Output Com. Maximum Capacitive The MKW15M series has limitation of maximum connected capacitance on the output. The power module may operate in current limiting mode during startup, affecting the rampup and the startup time. Connect capacitors at the point of load for best performance. The maximum capacitance can be found in the data sheet. Thermal Considerations Many conditions affect the thermal performance of the power module, such as orientation, airflow over the module and board spacing. To avoid exceeding the maximum temperature rating of the components inside the power module, the case temperature must be kept below 95. The derating curves are determined from measurements obtained in a test setup.
