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.
