HM1483 - 3.1A Monolithic Step-Down Switching Regulator

Description

HM1483 is a monolithic 30V, 3.0A step-down switch regulator.

HM1483 integrates a 36V 65mΩ high side and a 36V, 45mΩ low side MOSFETs to provide 3.0A continuous load current over a 6.5V to 36V wide operating input voltage with 30V input over voltage protection.

Features

  • 3.0A continuous output current capability.
  • 6.5V to 30Vwide operating input range with input Over Voltage Protection.
  • Integrated 36V, 65mΩ high side and 36V, 45mΩ low side power MOSFET switches.
  • Up to 95% efficiency.
  • Programmable Soft-Start limits the inrush current at turn-on.
  • Stable with Low ESR Ceramic Output Capacitors.
  • Fixed 300KHz Switching Frequency.
  • Input Under-Voltage Lockout.
  • Input over-voltage protection to protect device from working in h.
