Power module in compact QFN package

Intersil has announced the ISL8200M, a scalable power module. The module provides designers an easy-to-use general-purpose power solution that satisfies a range of POL (point-of-load) power requirements. This 10A, highly integrated POL regulator in a surface mount QFN package includes a PWM controller, power MOSFETs, power inductor and associated discrete components. The 15x15mm package and 2.2mm profile allow the module to be mounted on the back side of the PCB. The module accepts input voltages from 3 to 20V, and supports output voltages from 0.6 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 synchronisable switching frequency allows designers to optimise 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. The module is suitable for a range of applications in the computing, telecommunications and networking infrastructure, and industrial markets.
