NOTES:

1. O.V.P protection is across Vo1.
2. Consult factory for recommended reflow profile.
3. Typical start-up for 12Vin models is 9V. Maximum startup is 9.5V, with full operation down to 9.0V.
4. Operation is allowed to No-Load on single outputs, however operation below 10% load may cause ripple and noise to exceed spec.
5. External Capacitor required to meet conducted noise requirement.
6. Auxiliary output regulation on cross coupling of output channels. A 10% minimum load is required on Vo1 for regulation.
7. Output currents are maximum for each output however, max power is not to exceed rated power output. Please refer to table.
