The LM25576MH/NOPB is a SIMPLE SWITCHER® 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 42V, the LM25576 delivers 3A of continuous output current with an integrated 170mR 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 regulator to self-synchronize or to synchronize to an external clock. The regulator ensures robustness with cycle-by-cycle current limit, short-circuit protection, thermal shut-down and remote shut-down.
● Master or slave frequency synchronization
● Adjustable soft-start
● Emulated current mode control architecture
● Wide bandwidth error amplifier
● Built-in protection
● Green product and no Sb/Br
●This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
