30V power mosfet for non isolated dc/dc converter

Meanwhile, Hitachi and International Rectifier have been expanding their offerings in the higher power sector. Hitachi has unveiled a 30V power mosfet with chips for both sides of a non isolated dc/dc converter.

The package has two mosfets – one with a Schottky barrier diode – and says the device is suited to non isolated dc/dc converter applications.

The HAT2180RP converts a 5 to 20V supply into a 1.5 to 5V output. Higher speed and lower on resistance are claimed.

IR's L Series hexfet power mosfet is said to obviate the need for series Schottky and anti parallel high voltage diodes, reducing part count and improving power density. Targeted at zero voltage switching applications in circuits running at up to 250kHz, the 500V L Series has five members.
