Are you a power engineer? We need your help! We need you to evaluate a Buck Converter Reference Design. We’ll send you the hardware. We pay for everything. You get it keep it forever after you post a review.
Description
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.

- Microcontrollers for Power Supply Control (LogiCoA
Microcontroller): LogiCoA
Microcontrollers are suitable ones for power supply control with those analog-digital hybrid control is adopted and ML62Q2033/2035 and ML62Q2043/2045 are released. On this EVK, the ML62Q2035 is mounted.
- Operating System for Power Supply Control Microcontroller RMOS (Real time Micro Operating System). RMOS is a multi-task and real-time operating system developed to control switching power supplies and operates on ML62Q20xx group.
- Power Supply Application: Power Supply Applications are application circuits correspond to each power supply topology. On this EVK external components such as LDO, gate driver, operational amplifier, MOSFET inductor and so on are mounted as an application circuit of synchronous buck converter.
About the LogiCoA
LogiCoA Power is a solution adopting analog-digital hybrid control to a switching power supply. This user’s guide will provide the steps necessary to operate the evaluation board of LogiCoA
Power Solution Synchronous buck DCDC converter, LogiCoA001-EVK-001. Bill of materials, operating procedures and application data are included. LogiCoA
is the brand granted to the design philosophy of integrating digital elements to maximize the performance of analog circuitry. By fusing the merits of analog circuits with digital control, it brings out the full potential of circuit topology and contributes to higher efficiency of power utilization. ROHM thinks that this LogiCoA
can be applied not only to the power supply field but also to the overall power solution as. We are looking at future applications for products and solutions.
