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.
