60V Bidirectional 4-Switch Synchronous Buck-Boost Controller

Overview

TopologyBuck-Boost Converter
Input voltage9-60 V
Output 160 V / 10 A
IC revision1.00

Description

The ISL81601DEMO2Z demonstration board (shown in Figure 18 on page 15) features the ISL81601 and RL78G14. The ISL81601 is a 60V high voltage synchronous buck-boost controller. The RL78G14 is a 28 pin MCU that offers digital control and measurement for charge and discharge functions. The ISL81601DEMO2Z can adjust the input voltage and reverse current for charging, and can also adjust the output voltage and output current for discharging online.The ISL28022 is also used on this board to provide high accuracy voltage and current sensing and report to RL78 with IIC line. The ISL81601DEMO2Z can also report input and output voltage and current with high accuracy.
