Description

The LM5576 is an easy-to-use, 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 6V to 75V, the LM5576 delivers 3A of continuous

output current with an integrated 170mΩ N-Channel

MOSFET. The regulator uses 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 ICs from the LM(2)557x family to

self-synchronize or to synchronize to an external

clock. The LM5576 makes sure of robustness with

cycle-by-cycle current limit, short-circuit protection,

thermal shutdown, and remote shutdown. The device

is available in a power-enhanced, 20-pin HTSSOP

package that features an exposed die attach pad for

thermal dissipation. The LM5576 is supported by the

full suite of WEBENCH circuit design and selection

simulation services online design tools.
