EML9206 pdf datasheet

EML9206 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 600mA output current
capability. High 1.5MHz 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. EML9206 is
designed base on Pulse Width Modulation (PWM) for
low output voltage ripple and fixed frequency noise,
while Pulse Frequency Modulation (PFM) is used to
improve light load efficiency, and Low Dropout (LDO)
Mode provides 100% duty cycle operation. The device
is available in fixed output voltages of 1.2V, 1.8V and
3.3V in SOT-25 package.
