Product details

10A automotive buck in a 4.5x4 mm QFN

The Texas Instruments LP87521ERNFTQ1 is a single-output synchronous step-down DC/DC converter rated for 10 A continuous output at a 2 MHz switching frequency. 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.
