Product details
Overview
TPS65167RHAT from Texas Instruments is a highly integrated LCD bias power management IC for large-panel TFT-LCD TV and monitor applications. It delivers five regulated rails - Vs (15 V/1.7 A), VGH (30 V/50 mA), VGL (–5 V/150 mA), Vlogic (3.3 V/2.5 A), and Vaux (1.8 V/500 mA) - from a 6–14 V input, incorporating boost, buck, dual charge pumps, LDO controller, gate voltage shaping, and temperature sensing in a single 6 × 6 mm 40-pin QFN package.
For engineers reviewing the TPS65167RHAT datasheet, TPS65167RHAT pinout, TPS65167RHAT application, or TPS65167RHAT equivalent, this device is selected for compact, high-voltage sequencing in LCD panel power systems requiring precise gate driver rail control, thermal monitoring, and stress-test mode support.
Technical Context
The TPS65167RHAT integrates a 750 kHz fixed-frequency boost converter (Vs) with overvoltage protection up to 21 V, a 2.5-A step-down converter (Vlogic) with adjustable or fixed 3.3 V output, and independent positive/negative charge pumps operating at 1.5 MHz for VGH and VGL regulation. Its gate voltage shaping block uses an external high-voltage switch controlled via CTRL and GDLY pins to tailor VGH slew rate and timing.
It features a dedicated HVS pin enabling high-voltage stress test mode - on the TPS65167 variant (including TPS65167RHAT), both Vs and VGH outputs are elevated simultaneously - and includes internal soft-start, thermal shutdown (155 °C), short-circuit protection per rail, and a calibrated analog temperature sensor (5.7 mV/°C, ±6 °C accuracy).

Pinout & Package
TPS65167RHAT is housed in a thermally enhanced 40-pin QFN package (RHA suffix) with an exposed PowerPAD™ die pad connected to GND. The package supports high-current routing and efficient heat dissipation in space-constrained LCD panel designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VINB (Pin 1) | Buck converter input | Supplies power to the 3.3 V/2.5 A step-down regulator; bypassed with 0.47 µF capacitor. |
| SWB (Pins 3–4) | Buck switch node | Connects to external inductor and Schottky diode; requires low-inductance layout for EMI control. |
| FBB (Pin 8) | Buck feedback select | Grounding selects fixed 3.3 V output; resistor divider enables adjustable 1.5–5 V range. |
| REGOUT (Pin 9) | Internal 5 V regulator output | Provides bias for internal circuitry and external reference; requires 4.7 µF ceramic bypass. |
| REF (Pin 10) | 1.213 V reference output | Stable bandgap reference for all feedback loops; must be bypassed with 100 nF capacitor to GND. |
| DRVN (Pin 13) | Negative charge pump driver | Drives external flying capacitor network for VGL generation; supports –2 V to –5 V regulation. |
| SUP (Pin 19) | Positive charge pump input | Connected directly to Vs output; supplies energy for VGH charge pump stages (doubler/tripler). |
| POUT (Pin 21) | Positive charge pump output | Intermediate high-voltage rail feeding VGH gate-shaping switch; regulates up to 31 V (HVS mode). |
| VGH (Pin 22) | Final gate-on voltage output | High-impedance output shaped by external MOSFET; supports programmable rise/fall timing via GDLY. |
| DRN (Pin 23) | Gate-shaping low-side switch drain | Terminates external N-MOSFET; used with CTRL to control VGH discharge path during gate pulse tail. |
| CTRL (Pin 24) | Gate-shaping control input | Enables/disables VGH shaping block; tied to REGOUT when unused to bypass shaping function. |
| GDLY (Pin 25) | Gate delay timing capacitor | Connects to GND via capacitor to set delay between Vs stabilization and VGH activation (e.g., 10 nF = 2.3 ms). |
| EN (Pin 26) | Global enable with soft-start | Starts Vs, VGL, and POUT simultaneously; capacitor sets startup delay; pulled high to REGOUT for immediate start. |
| HVS (Pin 27) | High-voltage stress test control | When high, enables simultaneous Vs/VGH elevation for panel burn-in testing (TPS65167-specific feature). |
| RHVS (Pin 28) | HVS voltage set resistor | Pulled to GND during stress test to program elevated Vs voltage; open-circuit disables HVS mode. |
| FB (Pin 29) | Vs feedback input | Monitors Vs output via resistor divider; regulates to 1.146 V reference for 15 V nominal setting. |
| COMP (Pin 30) | Boost loop compensation | Accepts external RC network (e.g., 22 nF) to stabilize Vs regulation loop across load/temperature. |
| TEMP (Pin 31) | Analog temperature sensor | Outputs 1.2–2.5 V linearly proportional to die temperature (5.7 mV/°C); requires 1 nF output cap. |
| SW (Pins 34–35) | Boost switch node | Connects to external boost inductor and flyback diode; high dI/dt node demanding tight layout. |
| GD (Pin 36) | External isolation MOSFET gate drive | Controls high-side switch disconnecting Vs during fault; sinks 9 µA with 5 kΩ internal pull-up. |
| AVIN (Pin 38) | Analog supply input | Separate analog rail for internal references; bypassed with 0.47 µF capacitor for noise immunity. |
| FBLDO (Pin 39) | LDO controller feedback | Regulates external PNP-based Vaux (1.8 V/500 mA); reference voltage = 1.213 V ±2%. |
| BASE (Pin 40) | External PNP base drive | Sinks up to 25 mA to drive external transistor; current scales with Vaux load for stable regulation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LCD bias power management applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS65167ARHAT | TPS65167A variant; HVS mode elevates Vs only (not VGH), different RHVS behavior, identical pinout and core regulation. | Used where panel burn-in requires Vs stress only - e.g., source driver validation without gate line overstress. | Select TPS65167ARHAT when VGH stress testing is unnecessary and cost optimization is prioritized (A-grade qualification). |
| TPS65165RHAT | Lower current capability: Vs = 1.2 A (vs. 1.7 A), VGH = 30 mA (vs. 50 mA), no HVS mode, 32-pin QFN package. | Targeted at smaller panels (<24") or lower-resolution monitors with reduced gate/source drive demands. | Choose TPS65165RHAT for cost-sensitive, space-constrained designs where full TPS65167RHAT performance headroom is unused. |
Compared with TPS65167ARHAT and TPS65165RHAT, the TPS65167RHAT uniquely supports simultaneous Vs/VGH high-voltage stress testing and delivers higher VGH/VGL current for large-panel reliability - critical for 4K UHD TV panel production and burn-in validation.

FAQ
What is the maximum output current capability of the Vs rail on the TPS65167RHAT?
The TPS65167RHAT delivers up to 1.7 A continuous output current on the Vs rail (15 V nominal), supported by its integrated 750 kHz boost converter with 3.5-A peak switch current limit and thermal derating up to 85 °C ambient. This current level is validated across the full 6–14 V input range and meets typical source driver requirements for 40–65 inch LCD TV panels.
How does the gate voltage shaping function work on the TPS65167RHAT?
The TPS65167RHAT implements gate voltage shaping using the CTRL and GDLY pins to control an external high-voltage MOSFET between POUT and VGH. A capacitor on GDLY sets the delay between Vs stabilization and VGH activation, while CTRL enables/disables the shaping block. This allows programmable VGH rise/fall profiles to minimize panel crosstalk and improve image quality in large-format displays.
Does the TPS65167RHAT support high-voltage stress testing, and how is it enabled?
Yes, the TPS65167RHAT supports high-voltage stress testing for both Vs and VGH rails. It is enabled by pulling the HVS pin high, which activates internal circuitry to elevate Vs and VGH simultaneously - a feature specific to the TPS65167 (not TPS65167A). The RHVS pin is then pulled to GND to set the elevated Vs voltage, making it ideal for LCD panel burn-in validation.
What is the role of the TEMP pin on the TPS65167RHAT?
The TEMP pin on the TPS65167RHAT provides an analog voltage output (1.2–2.5 V) linearly proportional to the IC's junction temperature, with a slope of 5.7 mV/°C and ±6 °C accuracy. It drives up to 200 µA and requires a 1 nF output capacitor. This signal enables real-time thermal monitoring in fanless LCD enclosures and supports dynamic brightness throttling or fault logging in production test systems.
Can the TPS65167RHAT generate adjustable Vlogic output voltages, or is it fixed at 3.3 V?
The TPS65167RHAT supports both fixed and adjustable Vlogic outputs. When FBB is grounded, Vlogic is regulated to a precise 3.3 V ±2%. When FBB is connected to a resistor divider between Vlogic and GND, the output becomes adjustable from 1.5 V to 5 V - allowing compatibility with diverse timing controllers (TCONs) requiring non-standard logic supply voltages in custom LCD designs.
