ELM651DA CC/CV Mode 36V step down 5A DC/DC converter
â General description
ELM651DA is a step down switching regulator, which has a built-in 40V P-channel power MOSFET for
delivering output current. ELM651DA is designed to allow for operating a wide supply voltage range from 8V
to 36V and capable of delivering 5A output current.
ELM651DA 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.
