TPS65155 SLVSEE1 – SEPTEMBER 2017 TPS65155 LCD Bias Solution for LCD Monitors 1 Features 3 Description • • • • • The TPS65155 provides an integrated bias and level shifter solution for LCD monitors . 1 • • • • • • • 3-V to 6-V Input Voltage Range Boost Converter With 4-A Switch Current Limit Boost Converter Output Voltages up to 18 V Boost Converter Overvoltage Protection Selectable Switching Frequency (640 kHz or 1.2 MHz) Programmable Boost Converter Soft-Start Temperature-Compensated Positive Charge Pump Controller Negative Charge Pump Controller 4 + 2 Channels of Level Shifters XAO Reset Signal Thermal Shutdown 40-Pin 5×5 mm QFN Package The device integrates a boost converter to generate the source driver supply voltage (VAVDD), positive and negative charge pump controllers to generate gate driver ON (VGH) and OFF (VGL) voltages, and an 6channel level shifter in a single IC. The positive charge pump controller supports temperature compensation to reduce VGH at high temperatures. In addition to the above functions, the TPS65155 generates an additional active-low XAO reset output. Supply sequencing during power-up can be controlled by an externally generated enable signal.

Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications. 4.5 Glossary SLYZ022 — TI Glossary.

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design. PREVIEW: Device has been announced but is not in production. Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. (2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may reference these types of products as "Pb-Free". RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption. Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of
