EVAL-LTC7878-BZ

EVAL-LTC7878-BZ is an evaluation circuit featuring the LTC®7878: a 70V parallelable buck-boost controller with inductor DCR current sensing. The LTC7878 is a four-switch buck-boost switching regulator designed to operate above, below, or equal to the output voltage safely and easily. The constant-frequency, peak-current mode architecture allows phase-lockable switching frequency up to 600kHz. A programmable input or output current loop regulates the average input or output current loop, making it suitable for battery charging applications. Additionally, with a wide 5V to 70V input and output range and seamless, low-noise transition between operating regions, the LTC7878 is ideal for industrial and telecom systems. This board that can be easily modified to regulate output voltages from 1V to 70V. Its multiphase/multi-ICs parallel operation feature allows for simple alterations for higher power.
