Product details
Overview
TPS65196RHDR from Texas Instruments is a dual-channel, high-voltage LCD bias power supply IC integrating positive and negative charge-pump regulators, a VCOM buffer amplifier, and integrated level shifters - delivering ±15 V output capability with 30 mA sink/source current per rail, operating from a 2.7-V to 5.5-V input over –40°C to +85°C. It targets active-matrix LCD panel power management in industrial HMIs and portable medical displays.
For engineers reviewing the TPS65196RHDR datasheet, TPS65196RHDR pinout, TPS65196RHDR application, or TPS65196RHDR equivalent, key selection criteria include its integrated VCOM driver bandwidth (1.5 MHz), programmable VPOS/VNEG output voltage range (±8 V to ±15 V), and VQFN-28 (RHD) package thermal pad requirement for reliable high-current operation.
Technical Context
The TPS65196RHDR implements two independent switched-capacitor charge pumps - one for VPOS (positive bias), one for VNEG (negative bias) - each with external capacitor control and internal regulation feedback. Output voltages are set via resistor dividers on VPOS_SET and VNEG_SET pins, enabling precise tuning across display panel requirements.
It integrates a rail-to-rail output VCOM buffer capable of sourcing/sinking 100 mA peak, with gain set by external resistors, and includes dedicated logic-level shifters for TTL/CMOS-compatible interface control of enable, shutdown, and mode selection signals - all synchronized to minimize transient coupling in sensitive analog display paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.7 V to 5.5 V - supports single-cell Li-ion or regulated 3.3-V/5-V system rails without external LDO pre-regulation. |
| VPOS/VNEG Output Range | ±8 V to ±15 V - adjustable via external resistor dividers to match specific LCD panel threshold and gamma requirements. |
| Max Output Current | 30 mA per rail - sufficient for mid-size TFT-LCD panels up to 10.4″ with integrated gate drivers. |
| VCOM Buffer Bandwidth | 1.5 MHz - enables stable AC-coupled VCOM driving at frame rates up to 120 Hz without phase lag or distortion. |
| Operating Temperature | –40°C to +85°C - qualified for industrial-grade display modules deployed in uncontrolled ambient environments. |
| Package Thermal Resistance | θJA = 42°C/W - requires PCB thermal pad connection to achieve rated power delivery without derating. |
Pinout & Package
VQFN-28 (RHD) package with 5-mm × 5-mm body, 0.65-mm pitch, and exposed thermal pad (Pin 29) - requires soldering to PCB copper pour for thermal dissipation and EMI suppression. Pin 1 located in Quadrant Q2 per tape orientation standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Main power input | Supplies both charge pumps and internal LDOs; bypass capacitor required within 3 mm of pin. |
| VPOS_SET / VNEG_SET | Voltage setting inputs | Resistor-divider nodes that program regulated ±VOUT; high-impedance inputs requiring low-leakage resistors. |
| VCOM_IN / VCOM_OUT | VCOM amplifier I/O | Differential input accepts DC-biased VCOM reference; rail-to-rail output drives panel common electrode directly. |
| EN / SHDN | Enable/shutdown control | Active-high logic input with internal pull-down; asynchronous assertion disables all regulators and buffer to reduce quiescent current to 1 µA. |
| CP1/CP2/CP3/CP4 | Charge pump capacitor connections | Four dedicated terminals for external flying capacitors - placement and layout symmetry critical for ripple cancellation. |
| PGND / AGND | Power/Analog ground returns | Separate ground pins minimize noise coupling between switching and analog sections; must be joined only at single-point star ground. |
| EPAD (Pin 29) | Exposed thermal pad | Electrically connected to GND internally; must be soldered to ≥200 mm² PCB copper area with ≥4 thermal vias for thermal and mechanical reliability. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated dual charge pumps + VCOM buffer | Reduces BOM count by eliminating three discrete DC/DC converters and an op-amp stage in LCD bias designs. |
| Programmable ±8 V to ±15 V outputs | Enables single-part support across multiple LCD panel variants without hardware redesign or firmware change. |
| 1.5-MHz VCOM amplifier bandwidth | Supports fast-refresh industrial displays while maintaining <0.5% gain error and <1° phase shift at 60 Hz. |
| Logic-level shifters for control signals | Accepts 1.8-V/3.3-V/5-V logic inputs directly - eliminates external level translators in mixed-voltage systems. |
| VQFN-28 with thermal pad | Enables compact 5-mm × 5-mm layout footprint while sustaining 1.2 W continuous dissipation under full load. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LCD bias power supply applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS65195RHDR | Lacks integrated VCOM buffer; requires external op-amp for VCOM drive; same VPOS/VNEG architecture and pinout. | Suitable only when VCOM is generated externally or driven by separate circuitry - increases board area and component count. | Select TPS65195RHDR if VCOM path is already implemented elsewhere and cost reduction is prioritized over integration. |
| MAX17105ETL+ | Higher VPOS/VNEG output current (50 mA), but uses larger 32-pin TQFN; no integrated VCOM buffer; different control interface (SPI vs. GPIO). | Better suited for larger panels (>12″) or systems requiring digital voltage margining and telemetry reporting. | Choose MAX17105ETL+ when higher output current, SPI configurability, or extended diagnostics are required - not drop-in compatible. |
Compared with TPS65195RHDR and MAX17105ETL+, the TPS65196RHDR uniquely combines full LCD bias integration (dual charge pumps + VCOM buffer) in a compact 5-mm × 5-mm VQFN-28 package, enabling lowest-component-count solutions for mid-size industrial and medical displays.

FAQ
What is the maximum allowable output current per rail for the TPS65196RHDR?
The TPS65196RHDR delivers up to 30 mA continuous output current on both the VPOS and VNEG rails under typical conditions (TA = 25°C, VIN = 5 V). Derating applies above 60°C ambient or with poor PCB thermal design; full 30 mA operation requires proper thermal pad soldering and ≥200 mm² copper area.
Does the TPS65196RHDR require external components for basic operation?
Yes - the TPS65196RHDR requires four external flying capacitors (for charge pumps), input and output bypass capacitors, two resistor dividers (for VPOS/VNEG programming), and external gain-setting resistors for the VCOM buffer. No inductors are needed, as it operates on switched-capacitor topology.
Can the TPS65196RHDR drive VCOM directly without an external amplifier?
Yes - the TPS65196RHDR integrates a rail-to-rail output VCOM buffer capable of sourcing/sinking 100 mA peak current, designed to drive typical LCD panel common electrodes directly. External amplification is unnecessary unless >100 mA peak or specialized filtering is required.
What is the purpose of the exposed thermal pad (Pin 29) on the TPS65196RHDR?
The exposed thermal pad (Pin 29) on the TPS65196RHDR is electrically connected to GND and serves dual purposes: thermal dissipation (reducing θJA from 65°C/W to 42°C/W) and mechanical anchoring. It must be soldered to a dedicated PCB copper pour with ≥4 thermal vias to ensure reliability and prevent solder joint fatigue under thermal cycling.
Is the TPS65196RHDR RoHS-compliant and lead-free?
Yes - the TPS65196RHDR is RoHS-compliant with NIPDAU (nickel/palladium/gold) lead finish, rated MSL Level-2-260°C-1 year, and fully compatible with lead-free reflow processes. The device marking "TPS 65196" appears on the top surface, and packaging complies with TI's green packaging standards.
