EML3412
1.3MHz 1.2A, Synchronous Step-Down Regulator
General Description
EML3412 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 1.2A 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. EML3412 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. The
EML3412 is available in TDFN-6 package.
