Bel Power adds SIP modules to converter range

The modules operate at efficiencies of up to 94 per cent over an input range of 4.5V to 13.8V, and ultra-wide output-voltage trim range of 0.59 Vdc to 5.1 Vdc to help minimise manufacturers' BOMs.

The fixed-frequency devices are provided with active-high and true active-high enable logic, and feature an integrated heatsink to maximize usable power density.

Parts are RoHS EU Directive 2002/95/EC-compliant.

The converters are most commonly specified for PC board-mounted power applications in which a particularly small footprint is required.

They are suited to 12V input or 5V input distributed power architecture systems and are employed in data and enterprise networks.

They can also be used in telecommunication equipment, servers, storage and datacom equipment.

The Power SIP modules all switch at a fixed frequency (from 250KHz to 500KHz, module dependent), have a low input ripple current, remote on/off pin, and differential remote sense.

Additional control and protection features include input under-voltage lockout and output over-current/short-circuit protection.

The 60A and 80A modules are provided with a current-share pin that allows paralleled units to share current, while the 40A and 50A parts are offered in both vertical and horizontal configurations.

Pricing for the Power SIP Series of non-isolated DC/DC converters, in quantities of 10,000, is USD9.85 (GBP6), USD17.85 (GBP10.80), USD18.75 (GBP11.40), USD24.95 (GBP15.10), and USD25.95 (GBP15.70) for the 20A, 40A, 50A, 60A, and 80A models, respectively.

Samples and production quantities are available from stock with lead times of up to 12 weeks.
