Descrição geral do produto

The LM5574MT 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 to 75V, the LM5574 delivers 0.5A of continuous output current with an integrated 750mR 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 to 500kHz 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 LM5574 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 function
  • Emulated current-mode control architecture
  • Wide bandwidth error amplifier
  • Built-in protection
  • 1.5% Feedback reference accuracy
