regulator is an easy-to-use, synchronous, step-down DC/DC
converter that delivers best-in-class efficiency for rugged industrial applications.
The LM60430 drives up to
3-A of load current, and the
LM60440 is industrys
smallest 4A step-down converter.
The LM604x0 is available in an
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.
The LM604x0 uses peak-current-mode control to automatically fold
back frequency at light load to ensure exceptional efficiency across the entire load range. The low
power dissipation paired with a thermally optimized QFN package enables a power dense solution
size. In addition the device requires few external components and has a pinout designed for simple
PCB layout. The small solution size and feature set of the LM604x0 are designed to simplify
implementation for a wide range of end equipment.
This device is also
available in an AEC-Q100-qualified version.
