Product Overview
Product Description
LV56351JA 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   Benefits
  • Boost mode: Soft start function (t=2.8ms)
  • Can decrease a rush current
  • Boost : 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   End Products
  • Boost convertor attached LDO function
  • Power supply for BS/CS parabola antenna
