Intersil moves up the power food-chain with first integrated DC/DC module

April 15, 2014 // By Graham Prophet
Intersil’s ISL8216M is designed to supply 12V, 24V, 36V and 48V input rail applications for infrastructure and industrial equipment in a simple, flexible and thermally optimised solution.

ISL8216M is an 80-V, 4-A non-isolated DC/DC step-down power module. This integrated and simple-to-use module solution marks Intersil’s entrance into high voltage infrastructure and industrial applications. The module accepts an input voltage range from 10V up to 80V with an adjustable 2.5V to 30V output range, making it a flexible solution for 12V, 24V, 36V and 48V applications, including high voltage embedded board controllers. Using a single module, designers can optimise the power efficiency of their designs with minimal cost and decreased time to market.

The ISL8216M is a turnkey power module solution that requires only five external components, packaged in a rugged thermally enhanced 15 x 15 x 3.6mm over-moulded High-Density Array (HDA) format, which permits full load operation without a heat sink or fans. A suite of protection features includes over-current, over- / under-voltage and over-temperature shutdown.

Features include; output regulation of ±1% over -40°C to +85°C ambient range; programmable switching frequency of 200 kHz to 600 kHz, with a default of 300 kHz; frequency sync and power good, internal soft-start.

The power module is costs $15.50 (1,000); the ISL8216MEVAL1Z provides an evaluation platform for the ISL8216M, for $41.33.
