Power conversion

New single-output converters in Artesyn Technologies’ Typhoon series deliver up to 100A from a single-board, quarter-brick module with a profile of just 7.7mm.

New single-output converters in Artesyn Technologies’ Typhoon series deliver up to 100A from a single-board, quarter-brick module with a profile of just 7.7mm (0.3inch).

The two new isolated DC/DC converter introductions are the 100A, 1.2V-output LQS100A48-1V2, which offers a full load efficiency of 84.5%, and the 80A, 1.8V-output LQS80A48-1V8 with 89.7% efficiency at full load.

Future configurations will add 1.5, 2.5 and 3.3V output options.

The modules operate from a standard 48V-input supply – over the full 36 to 75VDC input voltage range – and offer an output voltage that is adjustable from 110% down to 80% of nominal value.

The converters feature short circuit, over-voltage and thermal protection, and use a single-board, open frame construction. The converters are characterised for operation up to +85 degrees C ambient, require no heatsink and have no minimum load requirement.

Additionally, the 80/100A devices have adopted the new industry-standard pin-out option known as ‘THE Double P’ – or THermally Enhanced Double Power pins. This provides an additional set of power and ground pins for current flow, addressing PCB manufacturing issues that can arise when attempting to route more than 50A through a single plated through-hole or via.

Samples are available for immediate delivery. In OEM quantities of 1000, unit prices start at $105.77, with a typical lead-time of 10 to 12 weeks.
