Datasheet

Aimtec's newest series of non-isolated, DC-DC switching regulators produce a high output current of 1A in a SIP3 package, measuring only 11.7 x 7.4 x 10.2mm for lower profile circuit implementations such as portable power and standby-power applications.

A feature rich alternative to 78xx linear regulators, the AMSR1-78Z step-down converters accept wide inputs ranging from 4.75-18VDC to 6.50-18VDC that step down to tightly regulated (±0.6%) output voltages starting as low as 1.5 to 5VDC, within efficiency rates as high as 94%.

While it is pin-to-pin compatible with the TO-220 package, the AMSR1-78Z does not require the heat sink, input and output capacitors or any of the other external components associated with traditional linear regulators.

The technical and cost benefits of the AMSR1-78Z's feature rich design include:
· simplified design process by eliminating the need to add ancillary
components;
· designed to operate at full output power without heatsink;
· high efficiency that eliminates the need for forced air cooling below +85°C;
· continuous output short circuit protection;
· more efficient use of valuable PCB board space.

The AMSR1-78Z series of DC-DC switching regulator converters operate continuously at full load below +60° C and within an ambient temperature range of -40° to +85°C. Made with high quality, RoHS compliant materials that undergo rigorous quality control to ensure reliability and performance, samples available from stock and can be ordered immediately.
