Complete High Efficiency DC/DC Power Module
ISL8204M, ISL8206M
The ISL8204M, ISL8206M is a family of pin-compatible power
modules to the ISL8201M. These are simple and easy to use,
high power DC/DC modules and are ideal for a wide variety of
applications. The ISL820xM family of high current DC/DC
step-down modules virtually eliminate design and manufacturing
risks while dramatically improving time to market.
The simplicity is in the family's "Off The Shelf" unassisted
implementation. All you need is the ISL820xM for the current
requirement of your design, bulk input and output capacitors and
one resistor, to program the output voltage, and you have a
complete high current power design ready for your market.
This family of buck converters is packaged in a thermally
enhanced compact (15mmx15mm) over-molded QFN Package
that operates without a heat sink, even at full load over
temperature. The package supports simple, reliable, automated
assembly using standard surface mount equipment while
making it easy to probe to all pins. The lack of a required heat
dissipation layer, provides easy access to all pins and the limited
number of the external components reduce the PCB to a
component layer and a simple ground layer.
Additionally, each IC in the family is foot print compatible,
making it easy to change your design to meet different power
needs without changing your layout. One simple layout fits all.
