EML3416
1.3MHz 1.5A, Synchronous Step-Down Regulator
General Description
EML3416 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 1.5A 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. EML3416 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 and
TDFN-8 package.
