LV52133A: Programmable DC-DC Converter, ±5 V Dual-Output, Single Inductor

  • LV52133A0XA and LV52133A5XA are dc-dc converters specifically designed for LCD panels. These DC-DC converters generate two different output voltages from a single inductor. Each of the output voltages are adjustable from ±4.1 V to ±5.7 V. LCD panel power modules using these dc-dc converters can be implemented within smaller board footprints, compared to converters that require dual inductors. The short circuit protection function, integrated for both positive and negative output pins, provides protection from continuous overcurrent when the output is shorted. This feature enhances the safety of the design. The extremely low standby current (0.3 μA typical) enables longer application operating time.
  • Features
  • Dual-Outputs by Single-Inductor architecture - Reducing total cost and mounting area
  • Adjustable both output voltages by I2C (I2C disable at standby) - Available for many kind of panels
  • Operating voltage range 2.5 V to 5.5 V - Available for almost battery
  • High speed inverted charge pump technology - High-speed response
  • Short Circuit Protection - Safety
  • Standby current dissipation 0.3 µA - Long operation time
  • Applications
  • Mobile LCD Panel Power Supply
  • End Products
  • Smart Phones
  • Tablets
