ISL8225M

Dual 15A/Single 30A Step-Down Power Module

Product Status: Mass Production

OVERVIEW

The ISL8225M is a fully-encapsulated step-down switching power supply that can deliver up to 100W output power from a small 17mm square PCB footprint. The two 15A outputs may be used independently or combined to deliver a single 30A output. Designing a high-performance board mounted power supply has never been simpler -- only a few external components are needed to create a very dense and reliable power solution.

Automatic current sharing and phase interleaving allow up to six modules to be paralleled for 180A output capability. 1.5% output voltage accuracy, differential remote voltage sensing and fast transient response create a very high-performance power system. Built-in output overvoltage, overcurrent and over-temperature protection enhance system reliability.

The ISL8225M is available in a thermally-enhanced QFN package. Excellent efficiency and low thermal resistance permit full power operation without heat sinks or fans. In addition, the QFN package with external leads permits easy probing and visual solder inspection.

Industry-Leading 10A and 15A Fully Encapsulated PMBus Power Modules

The ISL828xM hybrid digital and ISL821xM analog power modules feature integrated LDOs that enable single-supply operation. They leverage Renesas’ patented R4™ high-speed control loop architecture with inherent line voltage feed-forward, providing designers a unique combination of ultra-fast load transient response and high noise immunity. Their proprietary Grid HDA package offers unmatched electrical and thermal performance through a single-layer conductive package substrate that efficiently transfers heat from the module to the system board, and dissipates it without requiring airflow or heatsinks – even under heavy load conditions.
