FEATURES  
DESCRIPTION  
The LM27341 and LM27342 regulators are  
monolithic, high frequency, PWM step-down DC-DC  
converters in 10-pin SON and 10-pin MSOP-  
PowerPad packages. They contain all the active  
functions to provide local DC-DC conversion with fast  
transient response and accurate regulation in the  
smallest possible PCB area.

High Switching Frequency: 2 MHz  
LM27341 and LM27342 are easy to use. The ability  
to drive 1.5A or 2A loads respectively, with an internal  
150 mΩ NMOS switch results in the best power  
density available. The world-class control circuitry  
allows for on-times as low as 65 ns, thus supporting  
exceptionally high frequency conversion. Switching

synchronizable from 1 to 2.35 MHz, which allows the  
use of extremely small surface mount inductors and  
chip capacitors. Even though the operating frequency  
is very high, efficiencies up to 90% are easy to  
achieve. External shutdown is included featuring an  
ultra-low shutdown current of 70 nA. The LM27341  
and LM27342 utilize peak 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,
