说明
- STEVAL-ISA141V1, Evaluation Board based on the STBB3J is a fixed frequency, high-efficiency, buck-boost DC-DC converter which provides output voltages from 1.2 to 5.5 V starting from an input voltage in the range of 1.8 to 5.5 V. This device can operate with input voltages higher than, equal to, or lower than the output voltage making the product suitable for cell lithium-ion applications where the output voltage is within the battery voltage range. The MODE pin allows the selection between auto mode and forced PWM mode, taking advantage of either a lower power consumption or best dynamic performance
