Encapsulated in a tiny 9.0×6.5×1.83-mm QFN package, the ISL8203M step-down DC/DC power module from Intersil furnishes an adjustable output voltage between 0.8 V to 5 V to allow designers to use one device to build a single 6-A or dual 3-A output power supply.
The ISL8203M simplifies power-supply design for FPGAs, ASICs, microprocessors, DSPs, and other point-of-load conversions in communications, test and measurement, and industrial systems.
A complete power system, the ISL8203M includes a PWM controller, synchronous switching MOSFETs, inductors, and passive components in a single package supporting an input voltage range of 2.85 V to 6 V. It boasts high efficiency of up to 95% and 15°C/W thermal performance. The power device is capable of delivering 6 A at 85°C without the need for heat sinks or a fan. Other features include internal digital soft-start, enable for power sequencing, over-current protection, and over-temperature protection.
The ISL8203M is available now and costs $5.97 in lots of 1000 units. An evaluation board, designated the ISL8203MEVAL2Z, can be purchased for $67.
