NOTES:

1. Output power is up to 20W, see Io rating on "Model selection guide".
2. Model numbers are for SMD type pin configuration, replace suffix SM with TH for thru-hole type.
3. Typical start-up for 12Vin models is 9V. Maximum startup is 9.5V.
4. Operation is allowed to No-Load, however, operation below 10% load may cause ripple and noise to exceed spec.
5. All specifications are typical at nominal input, Full Load & 25C unless otherwise stated.
