DESCRIPTION
The LM5576Q0 is an easy to use SIMPLE
SWITCHER buck regulator which allows design
engineers to design and optimize a robust power
supply using a minimum set of components.
Operating with an input voltage range of 6 - 75V, the
LM5576Q0 delivers 3A of continuous output current
with an integrated 170mΩ N-Channel MOSFET. The
regulator utilizes an Emulated Current Mode
architecture which provides inherent line regulation,
tight load transient response, and ease of loop
compensation without the usual limitation of low-duty
cycles associated with current mode regulators. The
operating frequency is adjustable from 50kHz to
500kHz to allow optimization of size and efficiency.
To reduce EMI, a frequency synchronization pin
allows multiple IC’s from the LM(2)557x family to selfsynchronize
or to synchronize to an external clock.
The LM5576Q0 ensures robustness with cycle-by-
cycle current limit, short-circuit protection, thermal
shut-down, and remote shut-down. The device is
available in a power enhanced TSSOP-20 package
featuring an exposed die attach pad for thermal
dissipation. The LM5576Q0 is supported by the full
suite of WEBENCH? On-Line design tools.
