DC/DC switching regulators claim twice the efficiency at a quarter the size of linear regulators

The new  AMSRW-78Z differentiates itself with ultra wide (up to 8:1) input voltage range spanning from 9 to 72 VDC stepping down to highly regulated and protected output voltages ranging from 3.3 to 15 VDC.  

Alternatively, the new AMSRB-78-NZ offers a cost effective solution without compromise.  Wide (up to 6:1) input voltage range spanning from 4.5 to 30 VDC step down to regulated and protected outputs ranging from 3.3 to 15 VDC. The AMSRB-78-NZ features low output ripple and noise of 35 mV p-p, an important feature for noise sensitive applications.

Both AMSRW-78Z and AMSRB-78-NZ produce maximum output currents of 500 mA at efficiency rates of up to 96% that remain virtually constant over the entire input range. Operating continuously at full load without derating below +71° C (AMSRB-78-NZ) or +60° C (AMSRW-78Z), within an ambient temperature range of -40 to +85°C.eliminates the need for the costly heasinks associated with linear regulators.

Designed in a compact, SIP3 packages (11.68 x 9.65 x 7.50 mm), both series are pin compatible to the TO-220 package for low profile circuit implementations such as portable power and standby-power applications.

Featuring continuous short circuit protection, output current limit and thermal shutdown, samples of Aimtec’s AMSRW-78Z and AMSRB-78-NZ series of DC-DC switching regulator converters are available from stock and can be ordered through regional Franchised Distributors. Prices start at $7.75/1000+pieces.
