LY1152
Inverting DC/DC Controller (SOP)
GENERAL DESCRIPTION
The LY1152 is a high performance inverting DC/DC
controller, and the LY1152 designed to drive an
external power switch to generate adjustable
negative voltages. Output voltage can be scaled to
-40V.
The LY1152 quiescent current is about 90.0uA and
shutdown mode current can be reduced to 0.1uA.
In the LCD bias contrast application, efficiency of
80% can be achieved with low cost PNP bipolar
transistor drivers.
The LY1152 switching frequency can be around
60KHz to 160KHz range, and small size package is
ideally suited for powered portable equipments.
APPLICATION
Negative Voltage Supply.
Negative LCD Contrast Bias for
- Portable Data Collection Terminals.
- Notebook Computers.
