The LM5575 is an easy to use SIMPLE SWITCHER® buckregulator which allows design engineers to design and opTImizea robust power supply using a minimum set of components.OperaTIng with an input voltage range of 6 - 75V, theLM5575 delivers 1.5A of conTInuous output current with anintegrated 330mΩ N-Channel MOSFET. The regulator uTIlizesan Emulated Current Mode architecture which providesinherent line regulation, tight load transient response, andease of loop compensation without the usual limitation of lowdutycycles associated with current mode regulators. Theoperating frequency is adjustable from 50kHz to 500kHz toallow optimization of size and efficiency. To reduce EMI, afrequency synchronization pin allows multiple IC’s from theLM(2)557x family to self-synchronize or to synchronize to anexternal clock. The LM5575 guarantees robustness with cycle-by-cycle current limit, short-circuit protection, thermalshut-down, and remote shut-down. The device is available ina power enhanced TSSOP-16 package featuring an exposeddie attach pad for thermal dissipation. The LM5575 is supportedby the full suite of WEBENCH® On-Line design tools.
