ELM650DA CC/CV Mode 36V step down 2A DC/DC converter
General description
ELM650DA is a step down switching regulator, which has a built-in 40V P-channel power MOSFET for
delivering output current. ELM650A is designed to allow for operating a wide supply voltage range from 8V to
36V and capable of delivering 2A output current.
ELM650DA features programmable CV/CC mode control functions, the CV mode (Constant Voltage) function
to provide a regulated voltage output and the CC mode (Constant Current) function provide a current limitation
function, it is suitable for the DC/DC switching power applications when requested the current limitation
function.
