ARD00797, MCP16251 One-Cell Boost Converter with External UVLO Circuit Reference Design
참조 설계 작성자: Microchip Technology
ARD00797, MCP16251 Single Cell Boost Converter With External UVLO Reference Design provides an example of how to optimize applications powered from a single AA cell battery by incorporating a ultra low power external under-voltage lockout circuit with hysteresis. The converter will not (re)start if the battery voltage is lower than 1.14V and will stop working if the battery voltage drops below 0.83V. The external ULVO circuit drains approximately 0.1-0.4 uA before start-up and 1-2 uA after start-up
