Application Note: SY7088
2.3V Minimum Input and 5.5V Maximum Output
3A Peak Current Synchronous Boost with Output Disconnect
Preliminary Specification
General Description
SY7088 is a high efficiency synchronous boost
regulator that converts up to 5.5V output voltage. It
adopts NMOS for the main switch and PMOS for the
synchronous switch. It can disconnect the output from
input during the shutdown mode.
