Operating with an input voltage range of 6 V to 42 V, the LM25574-Q1 delivers 0.
5-A of continuous output current with an integrated 750-mΩ 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 50 kHz to 1-MHz 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 LM25574-Q1 guarantees robustness with cycle-by-cycle current limit, short-circuit protection, thermal shut-down, and remote shut-down.
The device is available in a TSSOP-16 package.
