LM2710
Step-up PWM DC/DC Converter Integrated with 5 Buffers
General Description
The LM2710 is a compact bias solution for TFT displays. It
has a current mode PWM step-up DC/DC converter with a
1.4A, 0.17
internal switch. Capable of generating 8V at
300mA from a Lithium Ion battery, the LM2710 is ideal for
generating bias voltages for large screen LCD panels. The
LM2710 can be operated at switching frequencies of 600kHz
or 1.25MHz, allowing for easy filtering and low noise. An
external compensation pin gives the user flexibility in setting
frequency compensation, which makes possible the use of
small, low ESR ceramic capacitors at the output. The
LM2710 uses a patented internal circuitry to limit startup
inrush current of the boost switching regulator without the
use of an external softstart capacitor. An external softstart
pin enables the user to tailor the softstart to a specific
application. The LM2710 contains a Vcom buffer and 4
Gamma buffers capable of supplying 50mA source and sink.
The TSSOP-20 package ensures a low profile overall solu-
tion.
