產品總覽

The LM5018MR/NOPB is a constant on-time synchronous Buck Regulator with integrated high-side and low-side MOSFETs. The constant-on-time (COT) control scheme employed in the LM5018 device requires no loop compensation, provides excellent transient response and enables very low step-down ratios. The on-time varies inversely with the input voltage resulting in nearly constant frequency over the input voltage range. A high-voltage startup regulator provides bias power for internal operation of the IC and for integrated gate drivers. A peak current limit circuit protects against overload conditions. The undervoltage lockout (UVLO) circuit allows the input undervoltage threshold and hysteresis to be independently programmed. Other protection features include thermal shutdown and bias supply undervoltage lockout.
  • No Schottky required
  • Constant on-time control
  • No loop compensation required
  • Ultrafast transient response
  • Nearly constant operating frequency
  • Intelligent peak current limit
  • Adjustable undervoltage lockout
  • Remote shutdown
  • Integrated 300mA high-side and low-side switches
  • Precision 2% feedback reference
  • Green product and no Sb/Br
