Tiny dual 3A / single 6A step-down DC-DC power module simplifies power supply design

20-01-2015 | Intersil | Power

Intersil has introduced the ISL8203M, a dual 3A / single 6A step-down DC-DC power module that simplifies power supply design for FPGAs, ASICs, microprocessors, DSPs and other point of load conversions in communications, test and measurement, and industrial systems. The module’s compact 9mm x 6.5mm x 1.83mm footprint combined with industry-leading 95 percent efficiency provides power system designers with a high-performance, easy-to-use solution for low-power, low-voltage applications. The ISL8203M is a complete power system in an encapsulated module that includes a PWM controller, synchronous switching MOSFETs, inductors and passive components to build a power supply supporting an input voltage range of 2.85V to 6V. With an adjustable output voltage between 0.8V and 5V, designers are able to use one device to build a single 6A or dual output 3A power supply. Designed to maximize efficiency, the ISL8203M power module offers best-in-class 15C/W thermal performance and delivers 6A at 85° C without the need for heat sinks or a fan. The ISL8203M leverages Intersil’s patented technology and advanced packaging techniques to deliver high power density and the best thermal performance in the industry, allowing the ISL8203M to operate at full load over a wide temperature range. The power module also provides over-temperature, over-current and under-voltage lockout protection, further enhancing its robustness and reliability. “Our customers are building increasingly compact DC/DC solutions,” said Mark Downing, senior vice president of infrastructure and industrial power products, Intersil. “The ISL8203M analog power module offers the smallest footprint for a dual output low power solution without performance compromise, making it possible for customers to get the footprint and the efficiency they require.” The ISL8203M power module is available now in a 9mm x 6.5mm, QFN package. The ISL8203MEVAL2Z evaluation kit is also available, says the company.
