- LogiCoA™ Solution BUCK Converter (12V Input, 5V Output, 25W)
LogiCoA001-EVK-001 is a reference design for a BUCK converter that uses ROHM's analog-digital fusion control technology LogiCoA™, which includes a microcontroller ML62Q2035 suitable for LogiCoA™, a 100V gate driver BD2320EFJ-LA, LDO BD950N1WG-C, BD900N1WG-C, operational amplifier BU7481SG, and shunt resistor LTR100LJZPFSR020. Design data, sample software, and an operating system for power supply control are available for this reference design, as well as a reference board. We hope that you will have a chance to experience the analog-digital fusion control LogiCoA™ and make use of it in your future power supply device development.
