Fremont, Calif. -- Exar Corp. introduces the XR79120 – a 20-A single output, synchronous step-down power module in a 12-mm x 14-mm x 4-mm footprint. Other key features include greater than 93% peak efficiency and Exar's patented advanced constant on-time (COT) control architecture across a 4.5V to 22V input voltage range.
The XR79120 provides a fully integrated power converter integrating MOSFETs, inductors, and internal input and output capacitors. The QFN-based package is said to provide superior thermal performance, easier electrical debugging and improved manufacturability with higher assembly yield and the ability to visually inspect solder joints. At 50°C with no airflow, no thermal de-ratings are required for output voltages of 1.8V and below.
Availability: The XR79120 will be available in a RoHS compliant, green/halogen free, 74-pin 12-mm x 14-mm x 4-mm QFN package.
Pricing: $13.95 in quantities of 1,000.
