Intersil Announces Industry's Smallest Dual 3A/Single 6A Step-Down Power Module

Intersil ISL8203M

ISL8203M delivers compact solution size, high power density and efficiency for infrastructure and industrial applications

Intersil - ISL8203M

Intersil Corporation announced the ISL8203M, a dual 3 A/single 6 A 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 9.0 mm × 6.5 mm × 1.83 mm footprint combined with industry-leading 95 percent efficiency provides power system designers with a high performance, easy to use solution for their 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 2.85 V to 6 V. With an adjustable output voltage between 0.8 V and 5 V, designers are able to use one device to build a single 6 A or dual output 3 A power supply.

Intersil - ISL8203M

Designed to maximize efficiency, the ISL8203M power module offers best-in-class 15° C/W thermal performance and delivers 6 A 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.
