DATASHEET ISL8204M, ISL8206M FN6999 Rev 4.00 Complete High Efficiency DC/DC Power Module October 28, 2014 The ISL8204M, ISL8206M is a family of pin-compatible power Features modules to the ISL8201M. These are simple and easy to use, Complete switch mode power supply in one package high power DC/DC modules and are ideal for a wide variety of applications. The ISL820xM family of high current DC/DC - ISL8204M - 4A with, 6.6A Peak step-down modules virtually eliminate design and - ISL8206M - 6A with, 8.8A Peak manufacturing risks while dramatically improving time to Single resistor sets V +0.6V up to +6V at 1% OUT market. Up to 95% efficiency The simplicity is in the family sOff The Shel unassisted Overcurrent protection implementation. All you need is the ISL820xM for the current requirement of your design, bulk input and output capacitors Internal soft-start with pre-bias output start-up and one resistor, to program the output voltage, and you have Wide input voltage range from 1VDC to 20VDC a complete high current power design ready for your market. Fast transient response This family of buck converters is packaged in a thermally enhanced compact (15mmx15mm) overmolded QFN Package Applications that operates without a heatsink, even at full load over Servers temperature. The package supports simple, reliable, automated assembly using standard surface mount Telecom and datacom applications equipment while making it easy to probe to all pins. The lack Industrial equipment of a required heat dissipation layer, provides easy access to all Point of load regulation pins and the limited number of the external components reduce the PCB to a component layer and a simple ground General purpose step-down DC/DC layer. Additionally, each IC in the family is footprint compatible, Related Literature making it easy to change your design to meet different power AN1386 ISL8201M, ISL8204M, ISL8206M EVAL1Z needs without changing your layout. One simple layout fits all.
