XR79120 is a fully integrated power converter integrating MOSFETs, inductors, and internal input and output capacitors. QFN-based package technology provides superior thermal performance, eases electrical debugging and improves 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.
The XR79120 occupies a 74-pin (multiple pins are paralleled for power connections) 12 x 14 x 4 mm QFN package. The XR79120 is priced at $13.95 (1,000).
