All models will effectively regulate under no-load conditions (with perhaps a slight increase in output ripple/noise). ➁ See Technical Notes/Performance Curves for additional explanations and details. ➂ Input Ripple Current is tested/specified over a 5-20MHz bandwidth with an external 33μF input capacitor and a simulated source impedance of 220μF and 12μH. See I/O Filtering, Input Ripple Current and Output Noise for details. ➃ The On/Off Control is designed to be driven with open-collector (or equivalent) logic or the applica- tion of appropriate voltages (referenced to –Input (pin 2)). Applying a voltage to the On/Off Control pin when no input voltage is applied to the converter can cause permanent damage. See Remote On/Off Control for more details. ➄ Extreme Accuracy refers to the accuracy of either trimmed or untrimmed output voltages over all normal operating ranges and combinations of input voltage, output load and temperature. ➅ Tie the Output Trim pin (pin 9) to +Output (pin 6) for maximum trim down or to –Output (Output Return/Common, pin 7) for maximum trim up. See Output Trimming for detailed trim equations. ➆ The Current-Limit-Inception point is the output current level at which the converter's power-limiting circuitry drops the output voltage 2% from its initial value. See Output Current Limiting and Short-Circuit Protection for more details. ➇ For Start-Up-Time specifications, output settling time is defined as the output voltage having reached ±1% of its final value at maximum load current. ➈ MTBF’s are calculated using TELCORDIA SR-332 Method 1 Case, ground fixed, +25°C ambient air and full-load conditions. Contact MPS for demonstrated life-test data. ➉ All models are fully operational and meet all published specifications, including "cold start," at –40°C. Use only as much output filtering as needed and no more. Larger caps (especially low-ESR ceramic types) may slow transient response or degrade dynamic performance. Thoroughly test your system with all components installed. |
