I am hoping to find a DC-DC converter IC/and or simple circuit that can take 90VDC and provide 5VDC @ ~ 20 mA. I note that the LT1339CSW from Linear Tech is a relatively inexpensive surface mount part, however, input voltages are limited to 60VDC. Can anyone suggest an alternative, workaround, or confirm that I am barking up the wrong tree? Thanks.
