3 Description
The LM76005 regulator is an easy-to-use
synchronous step-down DC-DC converter capable of
driving up to 5 A (LM76005) of load current from an
input up to 60 V. Tolerance goes up to 65 V, easing
input surge protection.
The LM76005 use peak-current-mode control to
provide exceptional efficiency and output accuracy in
a small solution size. Seamless transition between
PWM and PFM modes, along with very low MOSFET
ON resistances and an external bias input, ensures
exceptional efficiency across the entire load range.
This device requires few external components and
has a pinout designed for simple PCB layout with
best-in-class EMI (CISPR22) and thermal
performance. The small solution size and feature set
of the LM76005 are designed to simplify the
implementation for a wide range of end equipment.
The LM76005 device is available in the WQFN 30-pin
leadless package with wettable flanks.
