Analog Devices Inc. LTC7878 4-Switch Buck-Boost Controller is a high-performance switching regulator device operating from an input voltage above, below, or equal to the output voltage. A constant-frequency, peak current mode architecture allows up to 600kHz phase-lockable switching frequency. The programmable input/output current loop regulates the average input/output current to support battery charging applications accurately. A wide 5V to 70V input/output range and seamless, low-noise transitions between operating regions make the LTC7878 ideal for industrial and telecom systems.
