Intersil releases ISL8201M power-converter

It is an efficient, low-noise, highly integrated DC/DC power solution in a thermally enhanced QFN package.

It includes a high performance PWM controller capable of switching at 600kHz, power Mosfets, an inductor and all the passive components required for a complete DC/DC power solution.

The ISL8201M simplifies power-supply design, as only minimal external components are needed to implement a complete power solution.

This small form-factor saves considerable board space while the high integration reduces procurement and placement costs in applications such as telecommunication, data communication, electronic data processing, wireless network systems, medical and instrumentation and point-of-load applications based on a distributed bus architecture.

An onboard input-filter supports ultra-low noise operation, reducing EMI.

The ISL8201M can deliver 10A (17A peak) output current with up to 95 per cent efficiency, without the need for heat sinks or airflow to meet power specifications.

Other features include internal compensation, internal soft-start, auto-recovery over-current protection, an enable option and pre-biased output start-up capability.

The ISL8201M is housed in a tiny 15 x 15 x 3.5mm QFN package that offers optimum heat transfer through the PCB for excellent thermal performance.

A large copper plate under the package allows the ISL8201M to achieve a power density of approximately 200W/in3, roughly four times that of conventional open-frame modules, thereby eliminating the need for heat sinks.

The QFN package improves adherence to the PCB and improves overall reliability of end products.

All functional pins are brought out on the sides to make probing and debugging easier.

The ISL8201M is available in a 15-lead QFN package.
