General Description

The BD18364EFV-M is a buck-boost LED driver with

built-in 8 ch By-pass switch. Sequential winker and

animation lamp light circuits are made possible in this

circuit. The By-pass switch can be controlled ON and OFF

individually by micro-controller communication. In Bypass

switch control, generating high current can be

prevented from the current limit circuit.
