Product details
Overview
TPS65150PWP from Texas Instruments is a low-input-voltage LCD bias IC integrating boost converter (VVS up to 15 V), regulated negative charge pump (VVGL), regulated positive charge pump (VCPI/VVGH), gate-voltage shaping circuit, and VCOM buffer - all in a single HTSSOP-24 package. It delivers precise, sequenced bias rails for TFT LCD source/gate drivers and backplane control in space-constrained portable displays.
For engineers reviewing the TPS65150PWP datasheet, TPS65150PWP pinout, TPS65150PWP application, or TPS65150PWP equivalent, key selection criteria include its 1.8–6-V input range, <1% VVS output accuracy, adjustable power-on sequencing (DLY1/DLY2), integrated 2-A MOSFET switch, and dual charge pump regulation with gate-shaping capability via ADJ/CTRL pins.
Technical Context
The TPS65150PWP implements a virtual-synchronous boost converter operating at 1.2 MHz with CCM maintained across load conditions using an internal synchronous rectifier (Q2). Its feedback architecture uses a 1.146-V reference (FB) and external R-C compensation (COMP pin) for stable regulation under wide input and load transients.
It integrates three independent regulated outputs: a negative charge pump (VVGL) controlled by FBN feedback and DRVN drive, a positive charge pump (VVGH) controlled by FBP and DRVP with gate-shaping enabled via ADJ capacitor and CTRL signal, and a high-current VCOM buffer (1.2 A max) referenced to SUP and trimmed via IN pin.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 1.8 V to 6 V - supports direct operation from single-cell Li-ion, 2.5-V/3.3-V/5-V system rails without pre-regulation. |
| Main Boost Output (VVS) | Up to 15 V with <1% output voltage accuracy - ensures stable supply for TFT source drivers requiring tight voltage tolerance. |
| Negative Charge Pump (VVGL) | Regulated down to –2 V - provides precise negative gate bias for TFT gate drivers with load regulation of 0.016%/mA. |
| Positive Charge Pump (VVGH) | Up to 30 V (CTRL = GND, VVGH open) - delivers high-voltage positive gate drive with 1.214-V internal reference (FBP) and 0.07%/mA load regulation. |
| VCOM Buffer Output | 1.2 A maximum output current at 15-V SUP - drives large-panel VCOM capacitance without external amplification. |
| Gate-Voltage Shaping | Adjustable fall time via ADJ capacitor and CTRL signal - reduces image sticking by controlling VVGH slew rate during panel transitions. |
| Power-On Sequencing | Independent DLY1 (VVS→VVGL) and DLY2 (VVGL→VVGH) timing - eliminates need for external delay components in notebook/monitor startup sequences. |
Pinout & Package
TPS65150PWP is packaged in a thermally enhanced 24-pin HTSSOP (PWP) with exposed thermal pad soldered to GND. Pin functions are validated per TI SLVS576B datasheet Rev B (Jan 2016), with dedicated analog/power ground separation (GND vs PGND) and isolated charge pump driver paths.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Main input supply | Accepts 1.8–6-V rail; feeds boost converter, charge pumps, and VCOM buffer logic. |
| SW | Boost converter switch node | Connects to external inductor and synchronous rectifier; operates at 1.2 MHz with 2-A peak current capability. |
| FB | Boost output feedback | Senses VVS via resistor divider; references 1.146-V internal bandgap for <1% regulation accuracy. |
| DLY1 / DLY2 | Sequencing timing inputs | Capacitor-to-GND sets delay between VVS, VVGL, and VVGH ramp-up - enables application-specific startup order. |
| CTRL / ADJ / CPI | Gate-voltage shaping interface | CTRL enables/disables shaping; ADJ sets VVGH fall time; CPI routes VCPI to VVGH through internal isolation MOSFET (Q5). |
| VCOM | VCOM buffer output | Delivers buffered common-plane voltage; requires 1-µF output capacitor; supports ±150 mA load with ±85 mV load regulation. |
| GD | Gate-drive enable signal | Active-low open-drain output latched when VVS is in regulation - drives external P-MOSFET for VVS isolation. |
| REF | Internal reference output | 1.213-V precision reference used by FBN/FBP feedback networks and DLY/FDLY timing circuits. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated VCOM buffer | 1.2-A output current at 15-V SUP eliminates need for discrete op-amp or external buffer stage in TFT backplane designs. |
| Adjustable gate-voltage shaping | Configurable VVGH fall time via ADJ capacitor and CTRL signal - directly mitigates image retention in automotive and industrial LCD panels. |
| Virtual-synchronous boost topology | Maintains continuous conduction mode (CCM) at light loads using internal Q2 MOSFET - avoids SW-node ringing and simplifies EMI filtering. |
| Out-of-regulation protection | Adjustable fault delay (FDLY pin) triggers shutdown latch if VVS, VVGL, or VVGH drops below threshold - prevents display malfunction during brownout. |
| Thermal shutdown with hysteresis | 155°C trip point with 10°C hysteresis - protects device during sustained overload or poor PCB thermal design without oscillatory shutdown. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar LCD bias supply applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS65151PWP | Same HTSSOP-24 package and core architecture, but lacks VCOM buffer and gate-voltage shaping (no ADJ/CTRL pins); VVGH fixed at 24 V. | Targeted at simpler LCD modules where VCOM is generated externally and gate shaping is unnecessary. | Select TPS65151PWP only when VCOM buffering and dynamic VVGH control are not required - reduces BOM cost by ~15%. |
| TPS65136RGER | VQFN-24 package; includes VCOM buffer and charge pumps, but uses fixed 1.2-MHz oscillator (no soft-start adjustment) and lacks FDLY-based fault latch. | Better suited for space-constrained consumer displays where thermal pad soldering is preferred over HTSSOP leads. | Choose TPS65136RGER for new designs prioritizing thermal performance and smaller footprint - but verify fault response meets system safety requirements. |
Compared with TPS65150PWP, TPS65151PWP omits VCOM buffering and gate shaping - limiting use to basic bias-only applications - while TPS65136RGER trades adjustable fault timing and HTSSOP manufacturability for VQFN thermal efficiency and reduced board area.

FAQ
What is the maximum output current capability of the VCOM buffer in the TPS65150PWP?
The TPS65150PWP VCOM buffer delivers up to 1.2 A when supplied from a 15-V SUP rail, with output voltage regulation maintained within ±85 mV across ±150 mA load steps. This high-current capability allows direct driving of large-panel VCOM nodes without external amplification, reducing component count and layout complexity in notebook and monitor designs.
How does the TPS65150PWP implement power-on sequencing for VVGL and VVGH?
The TPS65150PWP uses two dedicated timing pins - DLY1 and DLY2 - each accepting an external capacitor to ground. DLY1 sets the delay between VVS stabilization and VVGL ramp-up; DLY2 sets the delay between VVGL regulation and VVGH activation. This fully integrated, capacitor-programmable sequencing eliminates external timers or microcontrollers in TFT display power-up sequences.
Can the TPS65150PWP generate both positive and negative gate bias voltages simultaneously?
Yes, the TPS65150PWP simultaneously generates regulated VVGH (positive, up to 30 V) via its positive charge pump and VVGL (negative, down to –2 V) via its negative charge pump. Both outputs feature independent feedback loops (FBP and FBN), adjustable load regulation, and fault monitoring - enabling full TFT gate driver biasing from a single IC without external charge pump stages.
What protection features are built into the TPS65150PWP?
The TPS65150PWP includes undervoltage lockout (UVLO), overvoltage protection (OVP) on SUP pin (16–20 V threshold), out-of-regulation detection with adjustable fault delay (FDLY pin), thermal shutdown (155°C with 10°C hysteresis), and internal current limiting on all switching elements. These protections ensure robust operation in automotive and industrial environments where input transients and thermal stress are common.
Is the TPS65150PWP pin-compatible with other members of the TPS651xx family?
No, the TPS65150PWP is not pin-compatible with most TPS651xx variants. While TPS65151PWP shares the same HTSSOP-24 package and many pin functions, it omits ADJ, CTRL, and VCOM-related pins. TPS65136RGER uses VQFN-24 packaging and differs in pin mapping and functionality. Always verify pin assignments and electrical characteristics against the specific device datasheet before substitution.
