1 / 20 page  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 Ω 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.
