  • LV56351HA integrates 1ch DC/DC boost converter and 1ch LDO. It is suitable as the power supply for BS/CS antennas of LCD/PDP TV and BD recorders that require automatic recovery without IC destruction and malfunction when the output is short-circuited.
  • Features
  • Boost mode:Soft start function (t=2.8ms) - Can decrease a rush current
  • Boost mode:Pulse by pulse over current protection function - Over current protection
  • Boost mode:Short circuit protection function - Short circuit protection
  • LDO mode:Over current limiter (fold-back characteristics) - limiting a over current. (damage protection for external parts)
  • Common:Under voltage lockout - Prevention of instability operation in under voltage
  • Common:Thermal shut down - Thermal protection
  • Common:Power good - Stability operation
  • Common:Internal fixed switching frequency(=425kHz) - No need to attach the external parts
  • Applications
  • Boost convertor attached LDO function
  • End Products
  • Power supply for BS/CS parabola antenna
