高效升压转换器TPS61221DCK的输出3.3V输出电路

This reference design describes a power option for MSP430 devices and accounts for voltage and current, requirements given below. The MSP430 devices require only a single 3.3-V input, so no sequencing is required. The operating input voltage for this reference design is between 0.7 V and 3.3 V. This design is optimized for very-low input voltage range and small design and low component count.
