Reference Design / Application Evaluation Kit

- Evaluation Board - BD8303MUV-EVK-001
This Evaluation Board uses a synchronous rectifying buck-boost DC / DC controller IC BD8303MUV to output 12V from an input voltage of 4V to 14V. BD8303MUV accepts a power supply input range of 2.7V to 14V. The output voltage can be set from 1.8V to 12V with an external resistor. The operating frequency can be set from 200kHz to 1MHz with an external resistor. The IC implements an efficient buck-boost converter using one inductor and external N-Channel FETs.
