LV52134A: Programmable DC-DC Converter, ±5 V Dual-Output, Single Inductor

  • LV52134A0XA and LV52134A5XA 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
  • VOUT1 default output voltage (+5.0 V / +5.5 V) - Provided a representative initial output value
  • VOUT2 default output voltage (–5.0 V / –5.5 V) - Provided a representative initial output value
  • Adjustable both output voltages by I2C (I2C disable at standby) - Available for many kinds of panels
  • Operating voltage range 2.5 V to 5.5 V - Available with many kinds of Battery
  • High speed inverted charge pump technology - High speed response
  • Short Circuit Protection - Safety
  • Standby current dissipation 0.3 µA - Long life of Li-ion Battery
