Description

The STEVAL-ISA141V1 evaluation board is based on the STBB3J fixed-frequency, high-efficiency, buck-boost DC-DC converter providing 1.2 to 5.5 V output voltages starting from a 1.8 to 5.5 V input voltage. The 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 selecting between auto mode and forced PWM mode, taking advantage of either a lower power consumption or the best dynamic performance.
