Product details
Overview
TPS65130RGER 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 TPS65130RGER datasheet, TPS65130RGER pinout, TPS65130RGER application, or TPS65130RGER equivalent, key selection criteria include dual-rail adjustability, independent enable sequencing, external P-channel FET control via BSW pin, 1-µA shutdown current, and VQFN-24 thermal performance (RθJA = 34.1°C/W).
Technical Context
The TPS65130RGER implements two independent fixed-frequency PWM regulators: a boost converter (VPOS) and an inverting buck-boost converter (VNEG), sharing only a common oscillator and 1.213 V internal reference. Each uses feedforward control monitoring VIN, output voltage, and switch RDS(ON) to dynamically adjust duty cycle without relying solely on slow error-amplifier loops.
It supports flexible power sequencing via separate ENP/ENN pins, optional power-save mode (PSP/PSN), soft-start (1 ms current-limit ramp), and load disconnect - the boost stage controls an external P-channel FET via BSW, while the inverter internally disables its PMOS switch to fully isolate the battery.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.7 V to 5.5 V - supports single-cell Li-ion (2.7–4.2 V), 3-cell alkaline/NiMH, or regulated 3.3/5 V rails without external LDO pre-regulation. |
| VPOS Output Range | +VIN+0.5 V to +15 V - adjustable via resistor divider on FBP pin; enables precise biasing of AMOLED source 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/DAC reference supplies. |
| Switch Current Limit | 800 mA (TPS65130) - sets maximum continuous output current per rail; determines inductor sizing and thermal derating at 85°C ambient. |
| Quiescent Current | 500 µA typical - enables low-power operation in always-on display subsystems; drops to 1 µA in shutdown mode. |
| Oscillator Frequency | 1.25–1.5 MHz - allows use of compact 4.7 µH inductors and reduces EMI filtering burden compared to sub-MHz converters. |
| Reference Voltage | 1.213 V ±1.3% - high-accuracy internal bandgap reference enabling <3% total DC output voltage accuracy across temperature. |
Pinout & Package
TPS65130RGER is housed in a thermally enhanced 4.0 mm × 4.0 mm VQFN-24 package with exposed thermal pad (RGE), supporting PCB-level heat dissipation (RθJB = 12.2°C/W) and surface-mount reflow compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| ENP (Pin 8) | Positive output enable input | Active-high logic control: enables VPOS generation and initiates soft-start; allows independent power-up sequencing with ENN. |
| ENN (Pin 10) | Negative output enable input | Active-high logic control: enables VNEG generation and initiates soft-start; decouples timing from VPOS for asymmetric rail startup. |
| FBP (Pin 22) | Positive feedback input | Connects to resistor divider from VPOS; regulates output by comparing divider voltage to 1.213 V reference. |
| FBN (Pin 16) | Negative feedback input | Connects to resistor divider referenced to VREF; regulates VNEG by comparing divider voltage to 0 V reference point. |
| BSW (Pin 7) | Battery switch gate driver | Open-drain output driving external P-channel FET gate; pulls low during VPOS operation to connect battery, floats/high-Z during shutdown to fully disconnect. |
| VREF (Pin 17) | Internal reference output | 1.213 V precision reference; bypassed with 220 nF capacitor; serves as ground reference for VNEG feedback divider. |
| PGND (Pins 2, 3) | Power ground return | Dedicated low-impedance path for high-current switch node return; must be separated from AGND to minimize noise coupling. |
| AGND (Pin 19) | Analog ground reference | Reference for feedback amplifiers and internal reference; connects to clean system ground plane near VREF and FB pins. |
Key Features
| Feature | Design Value |
|---|---|
| Independent dual-rail regulation | Enables non-symmetric outputs (e.g., +10.5 V / –10 V) with separate enable, soft-start, and power-save control - critical for display gamma correction and sensor biasing. |
| Integrated protection suite | Includes overvoltage lockout (±5% threshold), input UVLO (2.35 V typ), and thermal shutdown (150°C) with 5°C hysteresis - eliminates need for external fault monitoring circuitry. |
| External battery disconnect | BSW pin drives P-channel FET to break DC path from battery to boost inductor during shutdown - prevents standby current drain in portable medical or industrial HMIs. |
| Low-noise fixed-frequency PWM | 1.25–1.5 MHz operation minimizes output voltage ripple (<15 mVPP typical) and simplifies EMI filter design versus variable-frequency alternatives. |
| Thermally optimized VQFN-24 | 4 mm × 4 mm footprint with exposed thermal pad achieves 34.1°C/W junction-to-ambient rise - supports 500 mA continuous output at 85°C ambient without heatsink. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-output DC-DC converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS65131RGER | Higher 2 A switch current limit per rail; identical pinout and control interface. | Supports higher output currents (e.g., >500 mA VPOS/VNEG) in larger AMOLED displays or multi-channel DACs. | Select TPS65131RGER when peak load exceeds 800 mA per rail; otherwise TPS65130RGER offers lower quiescent current (500 µA vs 600 µA) and reduced thermal stress. |
| MAX17504ATP+ | Single-channel, wide-input (4.5–60 V) synchronous buck; requires external inverting stage for negative rail. | Used where high input voltage (>5.5 V) or higher efficiency (>92%) at heavy loads is prioritized over integration. | Choose MAX17504ATP+ only if input exceeds 5.5 V or system requires >90% efficiency at >1 A; TPS65130RGER provides full dual-rail integration at lower cost and smaller footprint. |
Compared with TPS65131RGER, the TPS65130RGER trades peak current capability for lower IQ and thermal margin - ideal for space-constrained 4–10" displays. Against MAX17504ATP+, it delivers complete dual-rail functionality in one IC but operates within a narrower input range.

FAQ
What is the maximum adjustable output voltage of the TPS65130RGER positive rail?
The TPS65130RGER positive output (VPOS) is adjustable up to +15 V, set by an external resistor divider connected to the FBP pin. This limit is defined by absolute maximum ratings (17 V at VPOS pin) and internal regulation architecture. Operation above +15 V risks overvoltage protection triggering or damage, and the device's 800 mA current limit assumes operation within this range. The TPS65130RGER datasheet specifies +VIN+0.5 V to +15 V as the valid adjustable range.
Does the TPS65130RGER support independent power sequencing between its positive and negative outputs?
Yes, the TPS65130RGER supports fully independent power sequencing via dedicated enable pins: ENP (Pin 8) controls the VPOS boost converter, and ENN (Pin 10) controls the VNEG inverting converter. Applying logic HIGH to either pin initiates soft-start and enables that rail alone, allowing staggered startup or shutdown - essential for meeting display panel timing requirements or avoiding latch-up in mixed-signal systems. The TPS65130RGER does not require simultaneous assertion of both enables.
How does the BSW pin function in the TPS65130RGER, and what external component is required?
The BSW (Pin 7) is an open-drain gate driver output that controls an external P-channel MOSFET placed between the battery and boost inductor. When ENP is HIGH, BSW pulls LOW to turn on the FET and connect the battery; when ENP is LOW, BSW floats to disconnect the FET and fully isolate the battery. A pull-up resistor (typically 10–100 kΩ to VIN) is required externally. This functionality is unique to the TPS65130RGER among dual-rail converters and enables true zero-standby-current shutdown.
What is the recommended input voltage range for reliable operation of the TPS65130RGER?
The TPS65130RGER is specified for reliable operation across 2.7 V to 5.5 V at the VIN pin. Below 2.7 V, performance degrades (e.g., reduced output current capability); below the UVLO threshold of 2.35 V (typical), the device shuts down entirely. The TPS65130RGER supports common sources including single-cell Li-ion (2.7–4.2 V), 3-cell alkaline (3.0–4.5 V), and regulated 3.3 V or 5 V rails - no external pre-regulator is needed within this range.
Can the TPS65130RGER generate symmetric ±12 V outputs, and what design considerations apply?
Yes, the TPS65130RGER can generate symmetric ±12 V outputs: VPOS is set via FBP divider (e.g., R1=1 MΩ, R2=110 kΩ), and VNEG is set via FBN divider referenced to VREF (e.g., R3=1 MΩ, R4=110 kΩ). Critical considerations include matching resistor tolerances (≤1%) to maintain symmetry, separating PGND and AGND planes, and using low-ESR ceramic capacitors (≥22 µF per rail) to suppress ripple. The TPS65130RGER's 3% total DC accuracy ensures ≤±0.36 V deviation across temperature.
