NOTES:
- Output Power is up to 20W, see Io rating on "Model Selection Guide".
- Model numbers are SMD type pin configuration, replace suffix SM with TH for Thru-hle type.
- Typical start-up for 12Vin models is 9V. Maximum startup is 9.5V.
- Operation is allowed to No-Load however operation below 10% load may cause ripple and noise to exceed spec.
