Aimtec has expanded its family of non-isolated, DC-DC switching regulator series with a surface-mount (SMD) version of the step-down switching regulators. Designed in a compact SMD package (15.24mm x 11.82mm x 7.25mm) to support automated assembly, the AMSRL-78-NZ series is suitable for low-profile circuit implementations such as portable- and standby-power applications. Versatile for a number of industrial applications, the AMSRL-78-NZ series is designed to operate at full output power without heatsinking or forced-air cooling below +71C and with output power derating up to +85C.With four models featuring adjustable output voltages, ranging from 1.8VDC to 15.5VDC, the AMSRL-78-NZ series produces maximum output currents of 500mA at efficiency rates of up to 96 per cent, with low output ripple and noise (25mV p-p) for noise-sensitive applications. Ultra-wide input ranges (up to 6:1) extend from 4.75VDC to 28VDC and allow the products to be powered from unregulated sources. Other features include continuous short-circuit protection on the output and thermal shutdown for added protection in overheating conditions.
The AMSRL-78-NZ input specifications also feature a remote on/off function, which conforms to TTL logic levels. Priced at USD5.60 (GBP3.40) per 1,000+ pieces, the AMSRL-78-NZ series is made with high-quality, RoHS-compliant materials that undergo rigorous quality control to ensure reliability and performance. Samples are available from stock and can be ordered immediately.
