80 V buck-boost battery charging controller integrates MPPT and I2C
Analog Devices, Inc. introduced the LT8491 buck-boost battery charging controller that features Maximum Power Point Tracking (MPPT), temperature compensation, and an I2C interface for telemetry and control. The device operates from input voltages above, below, or equal to the regulated battery float voltage. The LT8491 offers three selectable Constant Current Constant Voltage (CC-CV) charging profiles, […]
Bidirectional buck-boost, dual-phase buck DC/DC controllers handle 48-V apps
The ISL81801 buck-boost controller acts as a “UPS on a chip” by enabling bidirectional current flow (forward or reverse) using constant-voltage and constant-current regulation. This allows a battery or supercapacitor to be charged and discharged using a single controller and power path. The ISL81801’s combination of the industry’s highest 80V buck-boost switching frequency (600 kHz) […]
