Power Management ICs

FMD

Every application has its own special power supply demands. FMD offers a wide range of solutions, from 0.9 V to 500 V depending on the power requirements.

The highly affordable linear regulators (FT510 ... 33) are high-precision and offer low output noise (<30 μVrms) depending on the type, low quiescent current consumption (~ 1uA) and standby current of no more than 0.1μA.

The (FT435 ... 441) DC-DC power converter, developed e.g. for LED lighting products, combines high performance characteristics and very competitive prices. The most efficient boost converter achieves up to 97%.

FT83 AC-DC power converters are based on FMD’s own high-voltage CMOS process which allows the integration of 500V elements and the control circuit in a monolithic chip. This results in the lowest idle power dissipation and maximum efficiency and meets future legal requirements for energy saving in electrical appliances.
