Product details
Overview
TPS61089RNRR from Texas Instruments is a fully-integrated synchronous boost converter with 7-A continuous switch current, 2.7–12-V input range, and 4.5–12.6-V programmable output voltage-designed for high-pulse-current portable power applications such as Bluetooth speakers and quick-charge power banks.
For engineers reviewing the TPS61089RNRR datasheet, TPS61089RNRR pinout, TPS61089RNRR application, or TPS61089RNRR equivalent, key selection criteria include PFM light-load efficiency, resistor-programmable 7–10-A peak current limit, adjustable 200 kHz–2.2 MHz switching frequency, integrated 19-mΩ/27-mΩ MOSFETs, and 2.0-mm × 2.5-mm VQFN HotRod™ package thermal performance.
Technical Context
The TPS61089RNRR implements adaptive constant off-time peak current control to deliver fast line/load transient response with minimal output capacitance. It operates in quasi-constant-frequency PWM mode under moderate-to-heavy loads and switches to PFM mode at light load to maintain >70% efficiency down to 1 mA output current.
Its dual-MOSFET architecture integrates a 19-mΩ low-side switch and 27-mΩ high-side rectifier, enabling >18 W output from single-cell Li-ion (3.0–4.35 V) inputs. Protection includes cycle-by-cycle overcurrent, 13.2-V output overvoltage clamp, thermal shutdown at 150°C, and 200-mV UVLO hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.7 V to 12 V - supports single- or two-cell Li-ion/polymer battery inputs without external pre-regulation. |
| Output Voltage Range | 4.5 V to 12.6 V - resistor-divider programmable for USB PD, 9-V audio rails, or quick-charge adapter outputs. |
| Continuous Switch Current | 7 A - enables ≥18 W output power at 9 V from 3.6-V input with typical 90% efficiency. |
| Peak Current Limit | Programmable up to 10 A via ILIM pin resistor - allows robust pulse-current handling for speaker pop suppression or burst-mode loads. |
| Switching Frequency | 200 kHz to 2.2 MHz - adjustable via FSW-to-SW resistor to avoid EMI bands or optimize size/efficiency trade-offs. |
| Soft Start Time | 4 ms built-in - limits inrush current during startup, reducing stress on input capacitors and battery protection circuits. |
| Thermal Resistance | RθJA = 53.4°C/W (RNR package) - enables high-power density operation with minimal PCB copper area. |
Pinout & Package
TPS61089RNRR is housed in a 2.0-mm × 2.5-mm, 11-pin VQFN HotRod™ package (RNR) with exposed thermal pad for enhanced power dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW | Switching node | Connects internal low-side MOSFET drain and high-side MOSFET source; requires low-inductance layout to minimize ringing and EMI. |
| VIN | Main power input | Accepts 2.7–12 V; supplies both IC bias and power stage; must be decoupled with ≥10 µF ceramic capacitor near pin. |
| ILIM | Peak current limit programming | Resistor-to-GND sets switch current limit (e.g., 127 kΩ → 8 A); enables safe operation under short-circuit or high-pulse loads. |
| FB | Output voltage feedback | Senses divided VOUT to regulate output; reference voltage = 1.212 V (PWM), enabling precise 1% output accuracy. |
| FSW | Frequency setting | Resistor between FSW and SW sets switching frequency (200 kHz–2.2 MHz); prevents audible noise and EMI interference. |
| BOOT | High-side gate driver supply | Requires 0.1-µF ceramic capacitor to SW; ensures full enhancement of high-side MOSFET for low conduction loss. |
| VCC | Internal LDO output | 5.8-V regulated supply for control circuitry; requires ≥1.0 µF ceramic capacitor to GND for stability. |
| COMP | Error amplifier output | External RC network connects here for loop compensation; enables stable operation with wide inductor/capacitor selections. |
| GND | Power and signal ground | Common return for VIN, VOUT, and control signals; must be connected to thermal pad for optimal thermal performance. |
| VOUT | Boost output | Delivers regulated output up to 12.6 V; requires ≥10 µF output capacitance; protected by 13.2-V overvoltage clamp. |
| EN | Enable logic input | Active-high (≥1.2 V); pulls down internally at 800 kΩ; enables system-level power sequencing and standby control. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS61088RHLR | Same 7-A rating and 2.7–12-V input, but fixed 500-kHz frequency and no PFM mode; lower quiescent current (1.5 µA vs. 3 µA). | Lacks light-load efficiency optimization; better suited for noise-sensitive fixed-frequency systems than battery-run audio. | Select TPS61088RHLR only when predictable EMI profile and minimal IQ outweigh PFM efficiency gains. |
| MP2491DS-LF-Z | 6-A continuous, 2.5–13-V input, 4.5–13-V output; uses external MOSFETs; higher BOM count but supports >15-A peak with discrete FETs. | Requires external power switches and compensation; less compact but more flexible for ultra-high-current or custom thermal designs. | Choose MP2491DS-LF-Z when >7-A continuous or >12-A peak capability is required beyond TPS61089RNRR's integrated limit. |
Compared with TPS61089RNRR, TPS61088RHLR trades PFM efficiency for EMI predictability and lower IQ, while MP2491DS-LF-Z sacrifices integration and footprint for higher peak current scalability and external FET thermal management.

FAQ
What is the maximum output voltage supported by the TPS61089RNRR?
The TPS61089RNRR supports an output voltage range of 4.5 V to 12.6 V, set by an external resistor divider on the FB pin. Its internal overvoltage protection triggers at 13.2 V (typical), ensuring safe operation even under feedback fault conditions. This makes the TPS61089RNRR suitable for USB PD-compatible 9-V and 12-V rails in portable power designs.
Does the TPS61089RNRR support light-load efficiency optimization?
Yes, the TPS61089RNRR operates in PFM mode at light load to maintain >70% efficiency down to 1 mA output current. Unlike forced-PWM variants (e.g., TPS610891), this behavior reduces switching losses and audible noise-extending battery life in always-on portable audio and sensing applications where low-quiescent operation is critical.
How is the switching frequency programmed on the TPS61089RNRR?
The TPS61089RNRR switching frequency is set by a resistor connected between the FSW pin and the SW pin. Using the internal 24-pF capacitor and delay timing, a 301-kΩ resistor yields ~500 kHz, while 46.4 kΩ sets ~2.2 MHz. Leaving FSW unconnected is prohibited; the resistor must be placed directly per TI's layout guidelines to ensure stable frequency control.
What protection features does the TPS61089RNRR include?
The TPS61089RNRR integrates cycle-by-cycle overcurrent protection, 13.2-V output overvoltage protection with hysteresis, thermal shutdown at 150°C (with 20°C hysteresis), and input UVLO with 200-mV hysteresis. These features eliminate the need for external protection circuitry in space-constrained portable designs while ensuring robust operation under fault conditions.
Can the TPS61089RNRR be used with a single-cell Li-ion battery?
Yes, the TPS61089RNRR is explicitly designed for single-cell Li-ion (3.0–4.35 V) and two-cell Li-ion (6.0–8.7 V) inputs. Its 2.7–12-V input range, 7-A continuous switch current, and PFM efficiency mode make it ideal for boosting from 3.6-V nominal battery voltage to 9-V audio rails or 12-V display backlights without intermediate regulation stages.
