Unit/Comments

Min Typ Max

The 300WFS series 3 watts power modules are high

efficiency, surface mount dc-dc converters that operate over a

wide input voltage range of 9 - 18 VDC, 18 - 36 VDC and 36 - 75

VDC and provide precisely regulated output voltages of 3.3V,

5V, 12V, 15V, 5V, 12V and 15V.
