LT8705/A 4-Switch Buck-Boost DC/DC Controllers

Analog Devices Inc. LT8705/A 4-Switch Buck-Boost DC/DC Controllers are high-performance and operate from input voltages above, below or equal to the output voltage. The LT8705/A has integrated input current, input voltage, output current, and output voltage feedback loops. The LT8705/A is compatible with most solar, automotive, telecom, and battery-powered systems. The controllers feature a wide 2.8V to 80V input and 1.3V to 80V output range.
