3 Description
The LM2734Z
regulator is a monolithic, highfrequency, PWM step-down DC–DC converter assembled in a thick 6-pin SOT and a WSON nonpullback package. The device provides all the active functions to provide local DC–DC conversion with fast transient response and accurate regulation in the smallest possible PCB area.
With a minimum of external components and online design support through WEBENCH™, the LM2734Z is easy to use. The ability to drive 1-A loads with an internal 300-mΩ NMOS switch using state-of-the-art 0.5-µm BiCMOS technolog...
