Descrição geral do produto

The LM5576MH is an easy-to-use SIMPLE SWITCHER Buck Regulator, 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, it 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 50 to 500kHz to allow optimization of size and efficiency. To reduce EMI, a frequency synchronization pin allows multiple ICs from the LM(2)557x family to self-synchronize or to synchronize to an external clock. It ensures robustness with cycle-by-cycle current limit, short-circuit protection, thermal shut-down and remote shut-down. Supported by the full suite of WEBENCH On-Line design tools.
  • Integrated 75V, 170mR N-channel MOSFET
  • Ultra-wide input voltage range from 6 to 75V
  • Adjustable output voltage as low as 1.225V
  • 1.5% (Q1) and 1.65% (Q0) Feedback reference accuracy
  • Operating frequency adjustable between 50 and 500kHz with single resistor
  • Master or slave frequency synchronization
  • Adjustable soft-start
  • Emulated current mode control architecture
  • Wide bandwidth error amplifier
  • Built-in protection
Device has limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
