EVAL-LTC7878-AZ

EVAL-LTC7878-AZ 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. The EVAL-LTC7878-AZ operates from a 18V to 65V input voltage range and generates an output of 24V and at least a 20A load.

• Input voltage range from 18 to 65V at IOUT = 0A to 20A
• 24V typ output voltage at VIN = 18V to 65V
• 100KHz typ switching frequency
• 17.4V typ run rising threshold
• 98.2% typical efficiency
