Further space savings are achieved through current mode control, which reduces component count and by selecting a high switching frequency, reducing the inductor's footprint. The output voltage startup ramp is controlled by the SS\/TR pin which allows operation as either a stand-alone power supply or in tracking situations. Power sequencing is also possible by correctly configuring the enable and the open drain power good pins. Cycle-by-cycle current limiting on the high-side FET protects the device in overload situations and is enhanced by a low-side sourcing current limit which prevents current runaway. Hiccup protection will be triggered if the overcurrent condition has persisted for longer than the preset time. Thermal shutdown disables the part when die temperature exceeds thermal shutdown temperature. \u003cul\u003e \u003cli\u003eSynchronizes to external clock\u003c\/li\u003e \u003cli\u003eHiccup overcurrent protection\u003c\/li\u003e \u003cli\u003eMonotonic start-up into prebiased outputs\u003c\/li\u003e \u003cli\u003ePin-to-pin compatible with the TPS54620\u003c\/li\u003e \u003cli\u003eAdjustable slow start\/power sequencing\u003c\/li\u003e \u003cli\u003ePower good output for undervoltage and overvoltage monitoring\u003c\/li\u003e \u003cli\u003eAdjustable input undervoltage lockout\u003c\/li\u003e \u003cli\u003eSupported by SwitcherProâ�¢ software tool\u003c\/li\u003e \u003cli\u003eIntegrated 57\/50mR MOSFETs\u003c\/li\u003e \u003cli\u003e0.8V Voltage reference\u003c\/li\u003e \u003cli\u003e2µA Low shutdown quiescent current\u003c\/li\u003e \u003cli\u003eGreen product and no Sb\/Br\u003c\/li\u003e \u003c\/ul\u003e Applications \u003cp\u003e Consumer Electronics, Power 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 TPS54521RHLR\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\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.
