Description

The PL30502 is a 20-V synchronous Boost converter with the gate driver built-in for load disconnect.The PL30502integrates two low on resistance power FETs:A 7-mΩswitching FET and a 7-mΩrectifier FET.The PL30502 uses the adaptive constant off time peak current mode control.PL30502 has an internal feature to help improving light load efficiency.When output current is low,PL30502 will go into DCM mode.

The PL30502 includes configurable features include programmable cycle-by-cycle current limit and programmable switching frequency functions.

The PL30502 could isolate the output from input side when shutdown.Once the output is shorted,it enters into the hiccup mode to lower the thermal stress and can recover automatically after the short condition releases.Additionally,the PL30502 also has OVP and thermal protection to avoid the fault operation.The PL30502 is in a 3.0-mm x 3.5-mm 13-pin VQFN package with enhanced thermal dissipation.
