LM3211
Description
The LM3211 is a pact bias solution for TFT displays. It has a current mode PWM step-up DC/DC converter with a 1.4A, 0.17Ω internal switch. Capable of generating 8V at 300m A from a Lithium Ion battery, the LM3211 is ideal for generating bias voltages for large screen LCD panels. The LM3211 can be operated at switching frequencies of 600k Hz or 1.25MHz, allowing for easy filtering and low noise. An external pensation pin gives the user flexibility in setting frequency pensation, which makes possible the use of small, low ESR ceramic capacitors at the output. The LM3211 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 LM3211 contains 4 Gamma buffers capable of supplying 35m A source and sink. The TSSOP-20 package ensures a low profile overall solution.
