EML3023
1.5MHz 1A, Synchronous Step-Down Regulator
General Description
EML3023 is a high efficiency step down DC/DC
converter. It features an extremely low quiescent
current, which is suitable for reducing standby
power consumption, especially for portable
applications.
The device can accept input voltage from 2.5V to
5.5V and deliver up to 1A output current. High
1.5MHz switching frequency allows the use of small
surface mount inductors and capacitors to reduce
overall PCB board space. Furthermore, the built-in
synchronous switch improves efficiency and
eliminates external Schottky diode. EML3023 uses
different modulation algorithms for various loading
conditions: (1) Pulse Width Modulation (PWM) for low
output voltage ripple and fixed frequency noise, (2)
Pulse Frequency Modulation (PFM) for improving
light load efficiency, and (3) Low Dropout (LDO)
Mode for providing 100% duty cycle operation
during heavy loading. Adopting low reference
voltage design reduces regulated output to 0.6V.
The adjustable version of this device is available in
both of TDFN-6 2x2mm and SOT-23-5 package.
