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.
Features
• Complete switch mode power supply in one package
- ISL8204M - 4A with, 6.6A Peak
- ISL8206M - 6A with, 8.8A Peak
• Single resistor sets VOUT +0.6V up to +6V at ±1%
• Up to 95% efficiency
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.
• Overcurrent protection
• Internal soft-start with pre-bias output start-up
• Wide input voltage range from 1VDC to 20VDC
• Fast transient response
This family of buck converters is packaged in a thermally
enhanced compact (15mmx15mm) overmolded QFN Package
that operates without a heatsink, 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.
Applications
• Servers
• Telecom and datacom applications
• Industrial equipment
• Point of load regulation
• General purpose step-down DC/DC

Additionally, each IC in the family is footprint compatible,
making it easy to change your design to meet different power
needs without changing your layout. One simple layout fits all.
