Intersil introduces ISL8240M DC/DC converter

  • May 28, 2014

May 28, 2014 - Intersil announced ISL8240M, a dual 20A/single 40A step-down power module that delivers up to 100W of output power in a 2.9 cm2 footprint, greater than 90 percent power efficiency, and good thermal performance, the ISL8240M provides designers with a turnkey DC/DC converter solution for high current applications.   ISL8240M is pin-to-pin compatible with the company’s ISL8225M 30A power module, expanding the output current to 40A and delivering up to 100W output power. This offers designers a high level of flexibility, enabling a single PCB design across platforms. The ISL8240M is also capable of delivering up to 240A output when six modules in parallel operation are current shared, enabling the industry’s highest total output current.     The ISL8240M delivers greater than 90 percent power efficiency and thermal de-rating performance, allowing the ISL8240M to operate at full power over a wide temperature range. The module also provides over-temperature, over-current and over-voltage protection, further enhancing the robustness and reliability of the solution.   ISL8240M is a turnkey solution that requires minimal design since only six external passive parts are required.  The ISL8240M fits in a small 17mm x 17mm footprint. Excellent thermal performance eliminates the need for heat sinks, further streamlining power supply design and reducing design and manufacturing risk and increasing reliability.   Key Features and Specifications

  • Wide input voltage range: 4.5V to 20V
  • Adjustable output range: 0.6V to 2.5V
  • Capable of providing two separate outputs up to 20A per channel or a single 40A output with current sharing up to 6 modules in parallel operation for 240A
  • Achieves >90% efficiency (12Vin, 2.5Vout) at 40A
  • Full suite of protection features: over-current, over-/under-voltage, and over-temperature monitoring

Availability The ISL8240M power module is available now and priced at $39.85 (USD) each in 1,000-piece quantities. The ISL8240MEVAL3Z and ISL8240MEVAL4Z provide an evaluation platform for the ISL8240M and are priced at $88.00 (USD).
