It operates from a 2.8 V to 5.5 V input rail. The device is AEC-Q100 qualified and rated for an operating temperature range of -40°C to 125°C, which covers under-hood and cabin environments without derating concerns. The synchronous rectifier is integrated, so no external Schottky diode is needed — this saves board area and reduces BOM count in space-constrained ECU designs. ## Output voltage range and selection The output voltage is adjustable from a minimum of 0.6 V to a maximum of 3.36 V via an external resistor divider. ## Lifecycle and sourcing It is ROHS3 compliant.","metaTitle":"LP87521ERNFTQ1 Automotive Buck Converter, 10A, 2MHz","metaDescription":"LP87521ERNFTQ1 from TI — automotive step-down DC/DC converter, 10A output, 2MHz switching, 26-VQFN-HR wettable flank package.
