SynQor Inc. has expanded its NiQor family of non-isolated point of load (POL) converters with the introduction of the NQ15W50SGA30 device that delivers up to 30A in the DOSA standard 0.53 x 1.30-inch footprint and pinout.

The NQ15W50SGA30 POL offers a wide input voltage range of 6-15V, which allows for operation in a variety of Intermediate Bus Architecture (IBA) applications. The output can be programmed (using a single external resistor) to any value between 0.8V and 5.5V, and the new current share feature included in the device enables multiple devices to be connected in parallel to provide higher levels of load current. Efficiency of the device is as high as 93 percent.

The NQ15W50SGA30 is offered with a sequencing/tracking feature, which simplifies the implementation of various different output voltage timing requirements when using multiple POL devices in applications with multiple voltage chipsets, said the company. Control and protection features include remote sense, input undervoltage lockout, output OVP, current limit, short circuit protection and thermal shutdown. The operating temperature range is -40C to 105C. The devices are fully 6/6 RoHS compliant and offers a MTBF of nearly 11 million hours using MIL-HDBK-217F calculations.

The modules are priced at $17.90 in OEM quantities. Sample and production quantities are available immediately with a stock to eight week lead time.
