Product details
Overview
TPS65130RGERG4 from Texas Instruments is a dual-output DC-DC converter IC generating independent positive (up to +15 V) and negative (down to –15 V) rails from a 2.7–5.5 V input, with 800 mA current limit per output, 1.25–1.5 MHz fixed-frequency PWM control, and integrated overvoltage/thermal/UVLO protection-used in AMOLED display power supplies for industrial HMIs and test equipment.
For engineers reviewing the TPS65130RGERG4 datasheet, TPS65130RGERG4 pinout, TPS65130RGERG4 application, or TPS65130RGERG4 equivalent, key selection criteria include dual-rail sequencing capability, external P-channel FET gate control (BSW), 1-µA shutdown current, and VQFN-24 package compatibility with high-density PCB layouts.
Technical Context
The TPS65130RGERG4 implements two independent fixed-frequency PWM regulators: a boost converter for VPOS and an inverting buck-boost for VNEG, sharing only a common oscillator and internal 1.213 V reference. Each stage uses feedforward control with error amplifiers referenced to FBP/FBN pins for stable regulation under varying load and input conditions.
It supports flexible power sequencing via separate ENP/ENN enable inputs, power-save mode activation via PSP/PSN pins, and full load disconnect using the BSW gate driver for external PMOS. Thermal shutdown triggers at 150°C with 5°C hysteresis, and UVLO activates below 2.1–2.7 V on VIN.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.7 V to 5.5 V - supports single-cell Li-ion, 3-cell alkaline/NiMH, or regulated 3.3/5 V rails without external LDO pre-regulation. |
| VPOS Output Range | +0.5 V above VIN to +15 V - adjustable via resistor divider on FBP pin; enables biasing of TFT gate drivers or op-amp rails. |
| VNEG Output Range | –15 V to –2 V - adjustable via resistor divider on FBN pin; supports differential audio PA or ADC reference supplies. |
| Switch Current Limit | 700–900 mA per channel - ensures robust operation under short-circuit or high-capacitance load conditions. |
| Quiescent Current | 300–500 µA - maintains low system standby power in battery-powered HMIs and portable instrumentation. |
| Shutdown Current | 0.2–1.5 µA - minimizes battery drain during deep sleep modes in handheld medical or industrial devices. |
| Switching Frequency | 1.25–1.5 MHz - allows use of compact 4.7 µH inductors and reduces EMI filtering requirements. |
Pinout & Package
The TPS65130RGERG4 is housed in a thermally enhanced 4.0 mm × 4.0 mm VQFN-24 package (RGE) with exposed thermal pad for improved heat dissipation in space-constrained applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| ENP / ENN | Independent enable inputs | Allow precise sequencing of VPOS and VNEG startup/shutdown-critical for preventing latch-up in display bias circuits. |
| FBP / FBN | Feedback inputs | Connect to resistor dividers to set VPOS/VNEG output voltages; referenced to internal 1.213 V bandgap for ±3% DC accuracy. |
| BSW | External PMOS gate driver | Drives high-side P-FET to fully disconnect VPOS rail from battery during shutdown-eliminates parasitic discharge paths. |
| PSP / PSN | Power-save mode controls | Select continuous conduction (CCM) or pulse-skipping (PSM) operation per channel to optimize light-load efficiency. |
| PGND / AGND | Power and analog grounds | Separate ground pins reduce noise coupling between switching and feedback paths-essential for precision analog supply generation. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent outputs | VPOS and VNEG operate with non-symmetrical voltages/currents and separate enable/control-enables asymmetric biasing for OLED source/gate drivers. |
| Integrated protection | Per-rail overvoltage detection (±5% threshold), input UVLO (2.1–2.7 V), and thermal shutdown (150°C) prevent damage during fault conditions without external circuitry. |
| Low-noise regulation | Fixed-frequency PWM with feedforward control minimizes output ripple-supports sensitive analog circuits like DACs and differential op-amps. |
| Flexible sequencing | Individual ENP/ENN and PSP/PSN pins allow staggered startup, independent power-save entry, and controlled shutdown-required for display panel initialization sequences. |
| High-efficiency topology | Up to 89% (VPOS) and 81% (VNEG) peak efficiency at mid-load; combined 85% typical efficiency extends battery life in portable instrumentation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-rail DC-DC converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS65131RGER | Higher 1.8–2.2 A switch current limit per channel; identical pinout and control logic. | Better suited for higher-current AMOLED panels (>500 mA per rail) or multi-channel audio systems. | Select when load current exceeds 800 mA per rail; otherwise TPS65130RGERG4 offers lower cost and sufficient margin for most 4–12 inch displays. |
| MAX17504ATP+T | Single-channel, wide-input (4.5–60 V), no integrated negative output; requires external inverting stage. | Targeted at high-voltage industrial sensors or motor control bias rails-not drop-in for split-rail display supplies. | Consider only if redesigning for higher input voltage or needing >60 V input tolerance; adds complexity and board area versus integrated dual-output solution. |
Compared with TPS65131RGER, the TPS65130RGERG4 provides adequate current headroom for standard AMOLED biasing while reducing component cost and thermal stress; versus MAX17504ATP+T, it delivers true integrated dual-rail functionality with sequencing and protection-avoiding external inverter design effort and validation risk.

FAQ
What is the maximum output current capability of the TPS65130RGERG4 on each rail?
The TPS65130RGERG4 supports up to 800 mA per output rail (VPOS and VNEG) under typical conditions, with current limit thresholds specified from 700 mA to 900 mA depending on input voltage and temperature. This rating enables direct powering of gate driver ICs in mid-size AMOLED panels and analog front-ends in portable instrumentation without external current boosting.
Does the TPS65130RGERG4 support independent voltage programming for VPOS and VNEG?
Yes, the TPS65130RGERG4 supports fully independent voltage programming: VPOS is set via a resistor divider connected to the FBP pin (range: VIN+0.5 V to +15 V), and VNEG is set via a divider on the FBN pin (range: –15 V to –2 V). Both use the same internal 1.213 V reference, enabling asymmetric rail generation such as +10.5 V / –10 V for display biasing.
How does the BSW pin function in the TPS65130RGERG4, and what external component is required?
The BSW pin in the TPS65130RGERG4 is a gate driver output that controls an external P-channel MOSFET placed in series with the VPOS output path. When ENP is high, BSW goes low to turn on the PMOS; when ENP is low, BSW goes high to turn it off-fully disconnecting the VPOS rail from the input source. A Vishay Si2323DS or equivalent 12 V, 4 A P-FET is recommended per the datasheet.
What protection features are integrated into the TPS65130RGERG4?
The TPS65130RGERG4 integrates per-rail overvoltage protection (OVP) on both VPOS and VNEG, input undervoltage lockout (UVLO) with 2.1–2.7 V threshold, thermal shutdown at 150°C with 5°C hysteresis, and internal current limiting. These protections operate autonomously without external components-ensuring safe operation during faults in battery-powered or unregulated supply environments.
Can the TPS65130RGERG4 be used in automotive applications?
The TPS65130RGERG4 is not AEC-Q200 qualified and operates over –40°C to +85°C ambient (junction up to +125°C), making it suitable for under-dash industrial or medical devices but not for under-hood automotive applications. Its 2.7–5.5 V input range aligns with 12 V battery systems only when paired with a pre-regulator; TI recommends the TPS65150-Q1 for automotive-grade dual-rail display power.
