LM3211 - Step-up PWM DC/DC Converter

Download the LM3211 datasheet PDF. This datasheet also covers the LM3 variant, as both devices belong to the same step-up pwm dc/dc converter family and are provided as variant models within a single manufacturer datasheet.

General Description

The LM3211 is a compact 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 300mA from a Lithium Ion battery, the LM3211 is ideal for generating bias voltages for large screen LCD panels.

LM3211 Step-up PWM DC/DC Converter Integrated with 4 Buffers February 2004 LM3211 Step-up PWM DC/DC Converter Integrated with 4 Buffers General Description The LM3211 is a compact 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 300mA 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 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.
