Højt integreret og skalerbart powermodul

Intersil lancerer nu et ny powermodul i en QFN-pakning, der kan lette designprocesen markant (in english).

Intersil has announced the ISL8200M, a compact, scalable power module. This flexible module provides designers an easy-to-use general-purpose power solution that satisfies a wide range of point-of-load (POL) power requirements.

The ISL8200M is a 10A, highly integrated POL regulator in a surface mount QFN package that includes a PWM controller, power MOSFETs, power inductor and associated discrete components. It is ideally suited for a broad range of applications in the computing, telecommunications and networking infrastructure, and industrial markets.

Today, power system designers face considerable challenges, and performance demands continue to increase. Unless an engineer is an expert at power supply design, 'getting it right the first time' is very unlikely. Thanks to its robust, highly-integrated construction, the ISL8200M makes designing a high-performance POL regulator nearly foolproof, claims Intersil.

Constructing a high-performance POL regulator with the ISL8200M is fast and simple.  All you need are input and output capacitors, a few support components, and a single resistor to program the output voltage.

The ISL8200M's compact 15mm x 15mm package consumes very little PCB area.  And with its thin 2.2mm profile, the ISL8200M can be mounted on the back side of the PCB where space is typically free.

Patented current-sharing architecture

The ISL8200M accepts input voltages from 3V to 20V, and supports output voltages from 0.6V to 6V. A patented current-sharing architecture allows up to six modules to be paralleled for a total output current of 60A. Remote voltage sensing also assures precise regulation even in low voltage, high current applications.

Programmable and synchronizable switching frequency allows designers to optimize efficiency and control switching noise in noise-sensitive systems. An enable pin and power-good indicator can be used to sequence modules to meet FPGA and processor power sequencing requirements.

ISL8200M is assembled in a thermally enhanced surface mount QFN package with leads around the perimeter.  This provides for more reliable soldering, solder quality inspection and easy access with oscilloscope probes.
