LTC7878AUHTRPBF规格书详情
DESCRIPTION
The LTC®7878 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 EXTVCC auxiliary 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.
