SY20496
Description
The SY20496 high-efficiency synchronous Boost regulator converts down to 2V input and up to 5.5V output voltage. It uses a NMOS for the main switch and a PMOS for the synchronous switch. The device disconnects the output from the input during shutdown mode, and features programmable outputcurrent limit using the ILIM pin.
The SY20496 is available in a pact QFN2mmx2mm-10 package.
