LM60440-Q1 Automotive Synchronous Step-Down Converter

Texas Instruments' LM60440-Q1 automotive-qualified regulator is an easy-to-use, synchronous, step-down DC/DC converter that delivers best-in-class efficiency for automotive applications. This device is an ultra-small 4 A step-down converter. The LM60440-Q1 is available in an ultra-miniature WQFN package with wettable flanks and a standard QFN pinout with a thermal pad to enhance thermal performance. This enhanced QFN package features extremely small parasitic inductance and resistance, enabling very high efficiency while minimizing switch node ringing and dramatically reducing EMI.

The LM60440-Q1 uses peak-current-mode control to automatically fold back frequency at light-load to ensure exceptional efficiency across the load range. The low power dissipation paired with a thermally optimized QFN package enables a power-dense solution size. The device requires few external components and has a pin-out designed for simple PCB layouts. The small solution size and feature set of the LM60440-Q1 is designed to simplify implementation for a wide range of end equipment.
