The controller uses valley current mode architecture to achieve very low duty cycles with excellent transient response without requiring a sense resistor. The XREF pin is an external reference input that allows the user to override the internal 0.8V feedback reference with any lower value, allowing full control of the output voltage during operation, output voltage tracking or soft-start. This device has three current limit levels that can be chosen by connecting the RANGE pin to ground, open, and input respectively. It is widely used in application such as notebook and palmtop computers, PDA, portable instruments, distributed power systems etc.\u003c\/p\u003e\n  \u003cul\u003e\n   \u003cli\u003eWide VIN range is 2.2V to 22V\u003c\/li\u003e\n   \u003cli\u003eInternal boost provides 6V gate drive for VIN down to 2.2V\u003c\/li\u003e\n   \u003cli\u003eNo sensing resistor required\u003c\/li\u003e\n   \u003cli\u003eDual N-channel MOSFET synchronous drive\u003c\/li\u003e\n   \u003cli\u003eValley current mode control, optimized for high step-down ratio\u003c\/li\u003e\n   \u003cli\u003ePower good output voltage monitor\u003c\/li\u003e\n   \u003cli\u003eThree pin-selected current limit levels\u003c\/li\u003e\n   \u003cli\u003eInternal boost switching frequency is 1MHz typical\u003c\/li\u003e\n   \u003cli\u003eInput supply current is 0.6?A typical at (SHDN = 0V)\u003c\/li\u003e\n   \u003cli\u003eOperating temperature is -40°C to 85°C, package style is 16-lead plastic DFN\u003c\/li\u003e\n  \u003c\/ul\u003e\n  \u003ch3\u003eNotes\u003c\/h3\u003e\n  \u003cp\u003eADI products are only authorized (and sold) for use by the customer and are not to be resold or otherwise passed on to any third party\u003c\/p\u003e\n \u003c\/div\u003e\n\u003c\/div\u003e \u003ch4\u003eProduct details\u003c\/h4\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cdiv\u003e\n \u003cdiv\u003e\n  \u003cdiv\u003e\n   \u003cdiv\u003e\n    \u003cdiv\u003e\n     \u003cspan\u003eControl Mode\u003c\/span\u003e\n     \u003cp\u003eCurrent Mode Control\u003c\/p\u003e\n    \u003c\/div\u003e\n    \u003cdiv\u003e\n     \u003cspan\u003eSupply Voltage Max\u003c\/span\u003e\n     \u003cp\u003e22V\u003c\/p\u003e\n    \u003c\/div\u003e\n    \u003cdiv\u003e\n     \u003cspan\u003eDuty Cycle (%)\u003c\/span\u003e\n     \u003cp\u003e-\u003c\/p\u003e\n    \u003c\/div\u003e\n    \u003cdiv\u003e\n     \u003cspan\u003eNo. of Pins\u003c\/span\u003e\n     \u003cp\u003e16Pins\u003c\/p\u003e\n    \u003c\/div\u003e\n    \u003cdiv\u003e\n     \u003cspan\u003eTopology\u003c\/span\u003e\n     \u003cp\u003eSynchronous Buck (Step Down)\u003c\/p\u003e\n    \u003c\/div\u003e\n    \u003cdiv\u003e\n     \u003cspan\u003eOperating Temperature Max\u003c\/span\u003e\n     \u003cp\u003e85°C\u003c\/p\u003e\n    \u003c\/div\u003e\n    \u003cdiv\u003e\n     \u003cspan\u003eQualification\u003c\/span\u003e\n     \u003cp\u003e-\u003c\/p\u003e\n    \u003c\/div\u003e\n    \u003cdiv\u003e\n     \u003cspan\u003eSVHC\u003c\/span\u003e\n     \u003cp\u003eNo SVHC (21-Jan-2025)\u003c\/p\u003e\n    \u003c\/div\u003e\n    \u003cdiv\u003e\n     \u003cspan\u003eController IC Case Style\u003c\/span\u003e\n     \u003cp\u003eDFN-EP\u003c\/p\u003e\n    \u003c\/div\u003e\n   \u003c\/div\u003e\n   \u003cdiv\u003e\n    \u003cdiv\u003e\n     \u003cspan\u003eSupply Voltage Min\u003c\/span\u003e\n     \u003cp\u003e2.2V\u003c\/p\u003e\n    \u003c\/div\u003e\n    \u003cdiv\u003e\n     \u003cspan\u003eNo. of Outputs\u003c\/span\u003e\n     \u003cp\u003e1Outputs\u003c\/p\u003e\n    \u003c\/div\u003e\n    \u003cdiv\u003e\n     \u003cspan\u003eIC Case \/ Package\u003c\/span\u003e\n     \u003cp\u003eDFN-EP\u003c\/p\u003e\n    \u003c\/div\u003e\n    \u003cdiv\u003e\n     \u003cspan\u003eSwitching Frequency\u003c\/span\u003e\n     \u003cp\u003e1MHz\u003c\/p\u003e\n    \u003c\/div\u003e\n    \u003cdiv\u003e\n     \u003cspan\u003eOperating Temperature Min\u003c\/span\u003e\n     \u003cp\u003e-40°C\u003c\/p\u003e\n    \u003c\/div\u003e\n    \u003cdiv\u003e\n     \u003cspan\u003eProduct Range\u003c\/span\u003e\n     \u003cp\u003e-\u003c\/p\u003e\n    \u003c\/div\u003e\n    \u003cdiv\u003e\n     \u003cspan\u003eMSL\u003c\/span\u003e\n     \u003cp\u003eMSL 1 -
