Yenra : Energy : Power Converter : Ultra wide voltage range input with control and protection features, reliability, and low dissipation for wireless applications


SynQor releases a new family of Quarter Bricks targeting wireless applications and other areas where 24V, 48V or 60V inputs are supplied to the same board. The Power Qor PQ40 Giga series has a 4:1 operating input voltage range of 18-75V, and is offered in the industry standard Quarter Brick footprint and pinout. Available output voltages are 3.3V (25A) and 5V (20A).

The PQ40 Giga Series converters use synchronous rectification and SynQor's patented topology to achieve extremely high efficiency, low power dissipation and greater reliability, in a single board, open-frame package. The Power handling capabilities of the devices are such that at 3.3V out for example, no derating is necessary up to 55(degree)C ambient temperature with just 200LFM (1m/s) of forced air cooling, at both 24Vin and 48Vin.

The modules are capable of withstanding transients on the input to 100V for 100ms, and have a basic isolation level from input to output of 2000Vdc. Control and protection features include remote sense, voltage trim, input UVLO, output OVP, current limit, short circuit, and thermal shutdown. For those extended temperature applications needing direct contact to a thermal interface (such as an enclosed clamshell design for example), baseplated versions are also offered.

Sample and production quantities are available immediately with a stock to 8-week lead-time. The modules are priced at $58.00 in OEM quantities.

SynQor produces high efficiency dc/dc converters for distributed power architectures.
