MBZ type AL-E caps or POSCAPs may be used instead. * Output Ceramic Capacitance > 60µF located close to the module INPUT CAPACITANCE Although input capacitance value is not critical, the input capacitors must be capable of storing fairly large amounts of energy. The primary criteria, though, for choosing the input capacitors is AC ripple current rating. The SIP datasheet contains a chart showing ripple current vs. output current (or output power). The system designer determines the maximum SIP output current required from the SIP. Based on that number, the chart will show a corresponding ripple current rating the designer needs to plan for when choosing input capacitors. Suggested capacitors are OSCONS, MBZ type AL-E or POSCAPS. It is advised that the ripple current capacity of the capacitor be derated to the estimated ambient temperature. Capacitors of at least 16V are necessary and the user should also place >22µF of ceramics close to the module. Output Transient Response (Dynamic Loading) The output voltages will remain within their regulation limits specified for the load steps defined below. The maximum over/undershoot voltages will not exceed those defined below and will not cause any over or undervoltage detection circuits to activate. The load slew rate will not exceed 10A/µS. Recommended input and output capacitors should be used to meet the Spec.
