NDP1360KC6A,34V High Efficiency Synchronous Step-Down DC/DC ConverterZDescriptionNDP1360KC is a high efficiency, monolithic synchronous step-down DC/DC converter utilizing a constant frequency, average current mode control architecture. Capable of delivering up to 6A continuous load with excellent line and load regulation. The device operates from an input voltage range of 7V to 32V and provides an adjustable output voltage from 1V to 25V.The NDP1360KC features short circuit and thermal protection circuits to increase system reliability. The internal soft-start avoids input inrush current during startup.The NDP1360KC require a minimum number of external components. and a wide array of protection features to enhance reliabilityFeaturesl Wide VIN Range : 7V to 32Vl 6A Continuous Output Currentl Up to 95% Efficiency @ 24V Inputl Dual-Channel CC/CV Mode Controll Brick Wall Current Limitl Built in Adjustable Line-Compensationl Adjustable Output Voltagesl +/-1.5% Output Voltage Accuracyl +- 5% Current Limit Accuracy.l Integrated 8mΩ High Side Switchl Integrated 8mΩ Low Side Switchl Fixed 130KHz Frequencyl Burst Mode Operation at Light Loadl Internal loop Compensationl Internal Soft Startl Thermally Enhanced SOP8 PackageApplicationsl Car Chargerl Rechargeable Portable Devicesl Networking Systemsl Distributed Power SystemsTypical Application深圳市驪微電子科技有限公司電源方案開發(fā)設計半導體專業(yè)供應商Absolute Maximum Ratings (at TA = 25°C)CharacteristicsSymbolRatingUnitVIN to GND-0.3 to 34VSW to GND-0.3 to VIN+0.3VBST to GND-0.3 to VIN+6FB, FS to GND-0.3 to +6VCSP, CSN1, CSN2 to GND-0.3 to 25VJunction to Ambient Thermal Resistance105°C/WOperating Junction Temperature-40 to 150°CStorage Junction Temperature-55 to 150°CThermal Resistance from Junction to caseθJC15°C/WThermal Resistance from Junction to ambientθJA40°C/WPin Function And DescriptionsPINNameDescription1FBFeedback Of Output Voltage2CSPPositive input of Current Sense3CSN1Negative input of Current Sense14CSN2Negative input of Current Sense25GNDGround6VINPower Input7BSTBoot Strap8SWSwitching nodeConnected With a Inductor Order informationOrder InformationTop MarkingNDP1360 K CDY: Year (D8=2018,D9=2019,…)Pin NO.C:8PackageK: SOP8Product NumberWW: Weekly (01-53)X : Internal ID CodeElectrical CharacteristicsTJ = 25°C.
