Notes

1. Ripple & noise are measured at 20MHz of bandwidth by using a 12” twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.

2. Tolerance : includes set up tolerance, line regulation and load regulation.

3. Mounting holes M1 and M2 should be grounded for EMI purposes.

All specifications are typical at nominal input, full load, and 25°C unless otherwise noted
