The new regulated, fast-responding point-of-load (non-isolated) modules from Murata deliver 22-40W in four versions for FPGA and microprocessor applications. Members of the single-output MPDRX series include the MPDRX002S (28W at 0.8V to 1.8V from a 3-5V input); the MPDRX004S (22W at 0.8V to 1.8V, 7-14V input); the MPDRX103S (29W at 0.8V to 1.8V, 10.8-13.2V input); and the MPDRX104S (40W at 1.5V to 3.3V, 10.8-13.2V input).

These modules feature a transient response of 20?s typical (MPDRX002S) and 30?s (MPDRX004S, MPDRX103S and MPDRX104S), for a 50 to 100 percent load-current transient at di/dt = 2A/?s and for a return to within 50mV of set output. Output efficiency is up to 90 percent.

The POLs include Vout sensing circuitry, remote on/off (negative logic), and short-circuit and over-temperature protection. They're rated for operation over -40C to 85C. The POLs, in an SMD package measuring 33-by-13.5-by-8mm (MPDRX002S and MPDRX004S), and 50.8-by-5.8-by-14mm (SIL package, MPDRX103S and MPDRX104S), are offered at $10.25 each in volume orders. Lead time is approximately eight to 12 weeks.
