Analog Devices announced their ADP2441 DC-to-DC switching regulator. The ADI ADP2441 36-V, 1-A (amp) step-down regulator integrates both low-on-resistance, high-side and low-side power switches. The device provide compact point-of-load design and offers over 94% efficiency. Under light load conditions, the ADP2441 will automatically operate in PSM (pulse-skip mode) to reduce switching losses and improve energy efficiency. The ADP2441 is available now in 3 mm x 3 mm, 12 lead LFCSP packaging. It is priced at $1.78 each (1000 units volume).
The ADP2441 switching regulator supports a wide input range, from 4.5 V to 36 V. It is ideal for a diversity of point-of-load applications — including industrial and communication equipment and healthcare electronics. Output voltage is adjustable from 0.6 V to 90% of input voltage. The new regulator also offers low minimum on-time of 50ns (nano seconds).
