All models are tested and specied with a single, external, 0.47μF, multi-layer ceramic output
capacitor and no external input capacitors, unless otherwise noted. All models will effectively
regulate under no-load conditions (with perhaps a slight increase in output ripple/noise).
See Technical Notes/Performance Curves for additional explanations and details.
Input Ripple Current is tested/specied 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.
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.
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.
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.
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.
For Start-Up-Time specications, output settling time is dened as the output voltage having
reached ±1% of its nal value at maximum load current.
MTBF’s are calculated using TELCORDIA SR-332 Method 1 Case, ground xed, +25°C ambient air
and full-load conditions. Contact MPS for demonstrated life-test data.
All models are fully operational and meet all published specications, including "cold start," at –40°C.
Use only as much output ltering 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.
