3 Description
The PL30502 is a 20-V synchronous Boost converter with
the gate driver built-in for load disconnect. The PL30502
integrates two low on resistance power FETs: A 7-mΩ
switching FET and a 7-mΩ rectifier 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.
