1.3MHz 2A, Synchronous Step-Down Regulator 
General Description 
EML3418 is designed with high efficiency step 
down DC/DC converter for portable devices 
applications. It features with extreme low 
quiescent current with no load which is the best 
fit for extending battery life during the standby 
mode. The device operates from 2.5V to 5.5V 
input voltage and up to 2.0A output current 
capability. High 1.3MHz internal frequency 
makes small surface mount inductors and 
capacitors possible and reduces overall PCB 
board space. Further, build-in synchronous 
switch makes external Schottky diode is no 
longer needed and efficiency is improved.  
EML3418 is designed base on pulse width 
modulation (PWM) for low output voltage ripple 
and fixed frequency noise, low dropout mode 
provides 100% duty cycle operation. Low 
reference voltage is designed for achieving 
regulated output down to 0.6V. 
The device is available in an adjustable version 
for TDFN-8 and SOP-8FD package.
