General Description
The LM25575 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 - 42V, the LM25575 delivers 1.5A
of continuous output current with an integrated 330mΩ 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 1MHz 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 LM25575 guarantees 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-16
package featuring an exposed die attach pad for thermal dissipation. The LM25575 is supported by the full suite of WEBENCH On-Line design tools.
