15 Watt

Single and Dual Output
4:1 Wide Input


Ultra wide input with optional on/off control

Our 15 watt single and dual output DC-DC converter features an optional on/off control, six-sided continuous metal shielding, and 88% efficiency. With a standard low profile package of 1.00" x 2.00" x 0.40", this design has a minimum input/output isolation of 1600 Vdc and short circuit and over-voltage protection.
