Synchronous, step-down module uses COT control
12 June 2015 
The 20A single output, synchronous step-down power module measures 12 x 14 x 4mm, making it the industry’s smallest, says the company. It offers greater than 93% peak efficiency and leverages patented constant on-time (COT) control architecture across a 4.5 to 22V input voltage range.
The power converter integrates MOSFETs, inductors, and internal input and output capacitors. The QFN-based package technology is claimed to provide superior thermal performance, ease electrical debugging and improve 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 package is RoHS-compliant and halogen-free.
