Quarter bricks power up wireless power amps

Quarter brick convertors target wireless power amplifiers and other applications where 24, 48 or 60V inputs are supplied to the same board.

SynQor has expanded its family of quarter bricks targeting wireless power amplifiers and other applications where 24, 48 or 60V inputs are supplied to the same board.

The 8V output PQ40080QGA09 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 current is up to 9A.

The PQ40 Giga Series convertors 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 exceptional performance of the device means that no derating is necessary at 24V input, and full operation up to 70C without derating is possible at 48V input.

Full operating temperature range is -40 to +100C.

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 2000V DC.

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.
