LM5575QMH/NOPB

TEXAS INSTRUMENTS  LM5575QMH/NOPB  直流-直流开关降压逐步递减稳压器, 可调, 6V-75V输入, 1.225V-70V输出, 1.5A输出, HTSSOP-16

The is a SIMPLE SWITCHER® 75V 1.5A step-down Switching 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 to 75V, the LM5575Q delivers 1.5A of continuous output current with an integrated 330mR 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 LM5575 device to self-synchronize or to synchronize to an external clock. The regulator ensures robustness with cycle-by-cycle current limit, short-circuit protection, thermal shutdown and remote shutdown.
