Power efficient switching regulator family of non-isolated step-down converters delivers value for money

January 23, 2013 // By Paul Buckley
Aimtec’s new switching regulator family AMSRB-78-Z of is characterized by an efficiency of up to 94% and is now available for purchase from MSC.

The converter is a pin compatible alternative to the traditional 3-pin TO-220 package in LDOs (SIP3, 11.68 x 9.65 x 7.5mm), offering an attractive and economical alternative to standard linear regulators.
The Aimtec AMSRB-78-Z series delivers up to 7.5 W output power with 500 mA output current at efficiencies of up to 94% and a wide input voltage range from 4.5 VDC to 28 VDC. Moreover the switching regulator on a permanent short-circuit protection and a wide operating temperature range of -40 to +85 °C (rating from 70 °C / 65 °C at 12 V/15 V output)

The device offers a MTBF figure of more than  4,000,000 hours and regulated output voltages of 3.3, 5, 12 or 15 VDC.
The elimination of a heat sink and the low power consumption at light load and standby operation make the AMSRB-78-Z-series an power efficient and cost effective solution.
