The SE3608 is a high fficiency current- mode boost
converter with a fixed operation frequency. The
SE3608 integrates a very low Rds-on NMOSFET to
reduce power loss and achieve higher efficiency. The
maximum efficiency is up to 93%. SE3608 can output
2A current when Vin is higher than 3.3V and output is
5V. The high 1.2MHz operation frequency minimizes L
and C value. The internal compensation network
reduces extemal component counts. Small foot print
SOT23-6 package provides the best solution for PCB
layout area.
SE3608 is designed with 10V process. This allows
SE3608 to be used in applications where higher
voltage is needed, such as charging two Lithium
batteries in series. The other possible application
where the higher voltage is needed is Qualcomm
Quick Charge 2.0 compatible
portable chargers.
SE3608 can support 9V Vout for this application.
