This low-cost supply provides up to one watt of output Small Size0.55in 9.0cm power at 8 or 14 VDC (Vo) and an optional 3.3 or 5 VDC (Vr) output Low no-load input power <30mW for microprocessors, logic, timing circuits, transceivers, sensors or Constant power mode, not current limit other control functions. A patented design incorporating a custom 3000 VAC Isolation 3 3 integrated circuit into a small package (0.55 in 9.0 cm ) the BIAS Up to 75% efficiency Module provides an immediate drop-in solution, requiring no addi- EN 55022, Class B FCC Part 15, Class B tional external components.
