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.
