Description
General part information
LTC7878 Series
The LTC7878 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 600kHz, while a programmable input or output current loop regulates the average input or output current accurately supporting battery charging applications. With a wide 5V to 70V input and output range and seamless, low noise transitions between operating regions, the LTC7878 is ideal for industrial and telecom systems.The LTC7878 features forced continuous mode (FCM)/pulse-skipping mode operation. It supports multiphase/multi-ICs parallel operation for high power applications. Additional features include 7V N-Channel gate drivers, smart EXTVCCauxiliary supply and programmable inductor peak current limit. A PGOOD pin indicates when the output is within 10% of its designed set point.The LTC7878 is available in a low profile 32-Lead QFN package.APPLICATIONSIndustrial and Telecom SystemsDistributed DC Power or Battery Systems
