Ordering number : ENA1979
LV5636VH
Bi-CMOS Integrated Circuit
For BS/CS antennas
DC/DC converter
Overview
LV5636VH 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.
Functions

Caution 1) Absolute maximum ratings represent the value which cannot be exceeded for any length of time.
Caution 2) 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 degraded. Please contact us for the further details.
