The converters can operate in 5, 9, 12 or 15V systems and have integrated power transistors. The output voltage can be set externally using a resistor divider to any value between 0.8V and close to the input supply. Each converter features enable pin that allows a delayed start-up for sequencing purposes, soft-start pin that allows adjustable soft-start time by choosing the soft-start capacitor and a current limit (RLIMx) pin that enables designer to adjust current limit by selecting an external resistor and optimize the choice of inductor. The current mode control allows a simple RC compensation. 180° out of phase operation between Buck 1 and Buck 2, 3 (Buck 2 and 3 run in phase) minimizes the input filter requirements. \u003cul\u003e \u003cli\u003eWide input supply voltage range (4.5 to 18V)\u003c\/li\u003e \u003cli\u003e0.8V, 1% Accuracy reference\u003c\/li\u003e \u003cli\u003eAdjustable switching frequency\u003c\/li\u003e \u003cli\u003e300kHz to 2.2MHz Set by external resistor\u003c\/li\u003e \u003cli\u003eDedicated enable for each buck\u003c\/li\u003e \u003cli\u003eExternal synchronization pin for oscillator\u003c\/li\u003e \u003cli\u003eExternal enable\/sequencing and soft-start pins\u003c\/li\u003e \u003cli\u003eAdjustable current limit set by external resistor\u003c\/li\u003e \u003cli\u003eSoft-start pins\u003c\/li\u003e \u003cli\u003eCurrent-mode control with simple compensation circuit\u003c\/li\u003e \u003cli\u003eOptional low-power mode operation for light loads\u003c\/li\u003e \u003c\/ul\u003e Applications \u003cp\u003ePower Management\u003c\/p\u003e\u003ch4\u003eOther details\u003c\/h4\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eTEXAS INSTRUMENTS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003e TPS65251RHAR\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eQuantity\u003c\/td\u003e\n\u003ctd\u003eEach (Supplied on Cut Tape)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Change Notice EN\u003c\/td\u003e\n\u003ctd\u003e\u003ca href=\"https:\/\/www.farnell.com\/datasheets\/2608260.pdf\" target=\"_blank\" title=\"Download data sheet Texas Instruments TPS65251RHAR \u0026lt;b\u0026gt;TPS65251RHAR\u0026lt;\/b\u0026gt; Power Management IC 3 Synchronous Buck Converters 18 V Supply VQFN-40\" download\u003e\u003cimg src=\"\/\/cdn.shopify.com\/s\/files\/1\/1034\/1611\/files\/file_4379f50c-e237-48f9-beae-a4e625c5b304_icon.png?9736775303194905289\" alt=\"Download technical document - datasheet - Tanotis India\" width=\"25\"\u003e\u003c\/a\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"color: #999999;\"\u003eAll product and company names are trademarks™ or registered® trademarks of their respective holders.
