What are the key features of TPS65140PWP?
- 4-channel LCD bias supply with integrated positive charge pump eliminates external charge-pump components
- Adjustable output rails from 5 V to 15 V cover gate driver, source driver, and VCOM requirements for TFT-LCD panels
- 1.6 A minimum boost inductor current limit ensures stable power delivery under peak LCD driving load transients
- Integrated fault detection with enable sequencing for safe display power-on and power-off ramp control
What is TPS65140PWP used for?
TPS65140PWP is purpose-built for TFT-LCD power management in portable devices such as digital cameras, GPS navigators, handheld gaming consoles, and industrial HMI panels that require multiple precisely sequenced display bias voltages from a single Li-Ion battery. Its integrated charge pump and boost converter minimize external component count, reducing BOM cost and PCB area compared to discrete multi-rail approaches. The fault detection and adjustable output rails also make it suitable for e-paper and OLED hybrid display modules that share similar high-voltage gate driver requirements.

Frequently Asked Questions
What power rails does TPS65140PWP generate for a TFT-LCD panel bias supply?
TPS65140PWP generates 4 regulated output channels covering the typical TFT display bias requirements: a positive gate-driver voltage adjustable from 5 V to 15 V, a negative gate-off voltage, a VCOM bias rail, and an LDO-regulated 3.3 V logic supply. All channels are derived from a 2.7 V to 5.5 V input rail, making the device suitable for single-cell Li-Ion and dual-cell alkaline battery-powered display subsystems.
How does the integrated charge pump in TPS65140PWP reduce BOM cost compared to a discrete LCD power solution?
The fully integrated positive charge pump in TPS65140PWP generates the negative display voltage rail internally without requiring external charge-pump capacitors, diodes, or an additional switching IC. This replaces 4 to 6 discrete components in a traditional negative-rail boost design, saving approximately 2 mm² to 4 mm² of PCB area and reducing BOM component count by 30% to 40% in a typical portable display power supply design.
What boost current limit and fault protection features ensure reliable LCD operation in TPS65140PWP?
TPS65140PWP provides a 1.6 A minimum boost inductor current limit, preventing excessive coil saturation and output voltage collapse during the brief high-current transients that occur when LCD gate driver arrays switch rows simultaneously. Integrated fault detection monitors output voltages and disables the power stages on over-voltage or sequencing faults, protecting the display panel from exposure to out-of-specification bias voltages that would cause permanent pixel damage.
For a 3.5-inch TFT display in a portable medical device, what makes TPS65140PWP preferable to a multi-IC solution?
A 3.5-inch TFT panel typically needs AVDD at 6 V to 10 V, VGH at 16 V to 20 V, VGL at -4 V to -8 V, and VCOM around 3 V to 5 V — normally requiring 3 to 4 separate converter ICs. TPS65140PWP integrates all 4 channels in a single 24-pin TSSOP, reducing the total footprint to under 50 mm², simplifying EMC compliance by reducing switching node count, and achieving FDA design-control traceability through a single qualified component versus a multi-vendor discrete bill of materials.
