Analog Devices LT7930
The LT7930 is a high-performance, buck-boost switching regulator controller that operates from an input voltage above, below, or equal to the output voltage. The constant-frequency, peak current mode architecture allows a phase-lockable switching frequency of up to 1MHz, while a programmable input or output current loop regulates the average input or output current for accurately supporting battery charging applications. With a wide 5V to 72V input and output range and seamless, low-noise transitions between operating regions, the LT7930 is ideal for 48V input systems.FEATURES
