FEATURES  
DESCRIPTION  
The LM2734Z regulator is  
a
monolithic, high  
23  
•
Thin SOT-6 Package, or 6 Lead WSON  
Package  
frequency, PWM step-down DC/DC converter  
assembled in a 6-pin Thin SOT and WSON non pull  
back package. It provides all the active functions to  
provide local DC/DC conversion with fast transient  
response and accurate regulation in the smallest  
possible PCB area.

3MHz Switching Frequency  
300mΩ NMOS Switch  
With a minimum of external components and online  
design support through WEBENCH™, the LM2734Z  
is easy to use. The ability to drive 1A loads with an  
internal 300mΩ NMOS switch using state-of-the-art  
0.5µm BiCMOS technology results in the best power  
density available. The world class control circuitry  
allows for on-times as low as 13ns, thus supporting  
exceptionally high frequency conversion over the  
entire 3V to 20V input operating range down to the  
minimum output voltage of 0.8V. Switching frequency  
is internally set to 3MHz, allowing the use of  
extremely small surface mount inductors and chip  
capacitors. Even though the operating frequency is  
very high, efficiencies up to 85% are easy to achieve.  
External shutdown is included, featuring an ultra-low  
stand-by current of 30nA. The LM2734Z utilizes  
current-mode control and internal compensation to  
provide high-performance regulation over a wide  
range of operating conditions. Additional features  
include internal soft-start circuitry to reduce inrush  
current, pulse-by-pulse current limit, thermal  
shutdown, and output over-voltage protection.
