LV52133A
Programmable DC-DC Converter,
±5V dual-output, Single-Inductor
Overview
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 ±5.7V. 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 (0.3μA typical) enables longer
application operating time.
The differences of the LV52133A0XA-VH and LV52133A5XA-VH are
shown in below table.

1.Stresses exceeding those listed in the Maximum Rating table may damage the device. If any of these limits are exceeded, device
functionality should not be assumed, damage may occur and reliability may be affected.
2.Mounted on a specified board: 50mm×50mm×1mm (2 layer glass epoxy)
3.Absolute maximum ratings represent the values which cannot be exceeded for any length of time.
4.Even when the device is used within the range of absolute maximum ratings, as a result of continuous usage under high temperature, high
current, high voltage, or drastic temperature change, the reliability of the IC may be decrease. Please contact ON Semiconductor for the
further details.
