ISL8203M

Intersil Corporation has released a dual 3A/single 6A step-down DC/DC power module aimed at test and measurement, communications and industrial systems. Housed in a 9mm x 6.5mm x 1.83mm QFN package, the ISL8203M offers simplified power supply design for FPGAs, ASICs, microprocessors, DSPs and other point of load conversions.

The ISL8203M is a complete power system that integrates 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 maximise efficiency, the ISL8203M power module offers 15°C/W thermal performance and delivers 6A at 85°C without the need for heat sinks or a fan. The power module also provides over-temperature, over-current and under-voltage lockout protection.

The ISL8203M is priced at $5.97 in 1,000 quantities. The ISL8203MEVAL2Z evaluation can be purchased for $67 each.
