AME5235
n General Description
The AME5235 is a specific 40V HV buck converter
supports an output voltage range of 0.8V to 12V at 200KHz
switching frequency.
Protection features include under voltage protection,
over voltage protection, current limit, thermal shutdown,
and short circuit protection. The device is available in
SOP-8/PP package with exposed pad for low thermal
resistance.
