Single Supply Video Driver with
Reconstruction Filter and Charge Pump
The ISL59831 is a single supply video driver with
reconstruction filter and charge pump. It is designed to drive
SDTV displays with luma (Y) or composite video (CV)
signals. It operates on a single supply (3.0V to 3.6V) and
generates its own negative supply (-1.9V) using a regulated
charge pump. Input signal can be AC or DC coupled. When
AC coupled, the sync tip clamp sets the blank level to ground
at the output, ensuring that the sync-tip voltage level is set to
approximately -300mV at the back-termination resistor of a
standard video load. The ISL59831 is capable of driving two
AC or DC coupled standard video loads. The device also
features a 4
nominal -3dB frequency set to 9.1MHz, providing 44dB of
attenuation at 27MHz. When powered down, the device
draws 2µA supply current. Nominal operational current is
15mA. The ISL59831 is available in 12 Ld TDFN package
and operates from the -40°C to +85°C temperature range.

Ordering Information
NOTE: Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and 100%
matte tin plate termination finish, which are RoHS compliant and
compatible with both SnPb and Pb-free soldering operations. Intersil
Pb-free products are MSL classified at Pb-free peak reflow
temperatures that meet or exceed the Pb-free requirements of
IPC/JEDEC J STD-020.
