LM604x0/LM604x0-Q1 Step-Down Converter

Texas Instruments LM604x0/LM604x0-Q1 Synchronous Step-Down Converter is an easy-to-use, synchronous, step-down DC/DC converter that delivers best-in-class efficiency for automotive applications. The LM60430/LM60430-Q1 drives up to 3A load current, and the LM60440/LM60440-Q1 is a small 4A step-down converter. The Texas Instruments LM604x0/LM604x0-Q1 is available in an ultra-miniature WQFN package with wettable flanks and a standard QFN pin-out 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.
