LM5575

SIMPLE SWITCHER® 75V, 1.5A Step-Down Switching

Regulator

General Description

Features

The LM5575 is an easy to use SIMPLE SWITCHER® buck

regulator which allows design engineers to design and opti-

mize a robust power supply using a minimum set of compo-

nents. Operating with an input voltage range of 6 - 75V, the

LM5575 delivers 1.5A of continuous output current with an

integrated 330mΩ N-Channel MOSFET. The regulator uti-

lizes 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 self-synchronize or to synchronize to an

external clock. The LM5575 guarantees robustness with cy-

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

shut-down, and remote shut-down. The device is available in

a power enhanced TSSOP-16 package featuring an exposed

die attach pad for thermal dissipation. The LM5575 is sup-

ported by the full suite of WEBENCH^®On-Line design tools.
