Product details
Overview
TPS61376RYHR from Texas Instruments is a high-voltage non-synchronous boost converter with programmable input average current limit (0.1–3.0 A), true load disconnection via integrated ISO FET, and 4.5 A peak inductor current capability. It operates across 2.9 V to 23 V input and delivers up to 25 V output, targeting ePOS terminals, barcode scanners, and smart speakers requiring stable high-voltage boost with precise current limiting.
For engineers reviewing the TPS61376RYHR datasheet, TPS61376RYHR pinout, TPS61376RYHR application, or TPS61376RYHR equivalent, key selection criteria include its 1.2 MHz switching frequency, ±2.5% input current limit accuracy (at 1.5–3.0 A), HotRod™ Lite VQFN-13 (2.5 mm × 2.0 mm) package, and dual-mode PWM/PFM operation for wide-load efficiency.
Technical Context
The TPS61376RYHR implements peak current mode control with adaptive off-time topology, enabling quasi-constant-frequency PWM at moderate-to-heavy loads and seamless transition to PFM at light loads. Its internal error amplifier drives external compensation (COMP pin), while ISEL pin selects between 4.5 A (high) or 2.5 A (low) peak switching current limits.
True load disconnection is achieved by turning off the 40 mΩ ISO FET (VP–SW path) during EN shutdown, fully isolating input from output. Protection includes cycle-by-cycle overcurrent, output overvoltage (27.5 V typ), and thermal shutdown (150 °C rising / 130 °C falling).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input voltage range | 2.9 V to 23 V - supports single-cell Li-ion to multi-cell battery and industrial rail inputs |
| Output voltage range | 4.5 V to 25 V - programmable via FB resistor divider for diverse system rail requirements |
| Peak inductor current limit | 4.5 A (typ, ISEL = high) - sets maximum transient energy transfer and inductor sizing baseline |
| Input average current limit | 0.1 A to 3.0 A (programmable via ILIM pin resistor) - enables precise input power capping for USB-PD or battery protection |
| Switching frequency | 1.2 MHz - allows compact magnetics and low-profile ceramic capacitors (CIN ≥ 10 µF, COUT ≥ 10 µF) |
| ISO FET on-resistance | 40 mΩ (ISEL = high) - ensures low-loss true load disconnect with <100 mV drop at 2.5 A |
| Reference voltage (FB) | 1.0 V ±1.5% (–40 °C to 125 °C) - defines output regulation accuracy and sets feedback divider ratio |
Pinout & Package
TPS61376RYHR uses a 13-pin HotRod™ Lite VQFN package (2.5 mm × 2.0 mm, 0.5 mm pitch) with exposed thermal pad for enhanced power dissipation. Pin numbering follows top-view orientation per TI SLVSGQ1B.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Power input | Primary IC supply rail; powers internal LDO when VIN > 5.5 V, otherwise sourced from VOUT |
| EN/UVLO | Enable & UVLO input | Logic-enable pin with accurate 0.813 V threshold; supports programmable VIN UVLO via resistor divider |
| ISEL | Current limit scaling control | Configures peak switch current: 4.5 A (high) or 2.5 A (low); improves ILIM accuracy below 750 mA when low |
| VOUT | Boost output | Main regulated output node; connects to load and output capacitor (COUT) |
| VP | ISO FET drain | Connects to isolation FET source (SW) - forms true input–output disconnect path when disabled |
| SW | Switching node | Drain of low-side FET and source of ISO FET; requires low-ESR ceramic boot capacitor (≥0.47 µF) |
| PGND | Power ground | High-current return path for VIN, SW, VP, and VOUT; must be separated from AGND for noise immunity |
| FB | Voltage feedback | Senses output via resistor divider; 1.0 V reference enables precise output setting (e.g., 12 V = R1/R2 = 11) |
| COMP | Error amplifier output | Connects external RC compensation network (RCOMP/CCOMP) to stabilize loop response |
| ILIM | Average current limit set | Resistor-to-AGND sets 0.1–3.0 A input current limit; not floating - ties directly to accuracy spec |
| VCC | Internal regulator output | 4.8 V regulated supply; requires ≥1 µF ceramic decoupling to AGND for gate driver stability |
| AGND | Analog ground | Reference for FB, COMP, ILIM, and internal circuits; must be star-connected to PGND at single point |
| BOOT | Bootstrap supply | Drives ISO FET gate; capacitor between BOOT and SW provides high-side gate drive voltage swing |
Key Features
| Feature | Design Value |
|---|---|
| True load disconnection | ISO FET (40 mΩ) fully breaks VIN–VOUT path during EN=low, eliminating reverse leakage and enabling safe hot-swap |
| Programmable input average current limit | 0.1–3.0 A with ±2.5% accuracy (1.5–3.0 A range), implemented via single ILIM resistor without external sense resistor |
| Adaptive PWM/PFM operation | Seamless mode transition maintains >85% efficiency from 10 µA to full load; PFM reduces light-load quiescent current to 2 µA |
| Integrated dual MOSFETs | Low-side FET (50 mΩ) + ISO FET (40 mΩ) eliminate external switches and reduce BOM count and layout area |
| Robust protection suite | OVP (27.5 V), cycle-by-cycle OCP, thermal shutdown (150 °C), and soft-start (4 ms) prevent fault propagation and inrush damage |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS61088RHLR | Lower max input (18 V), no true load disconnect, fixed 4.5 A peak current, no ILIM pin - uses external sense resistor for current limit | Lacks input current programming and ISO FET; unsuitable where battery protection or hot-swap isolation is required | Select only if cost sensitivity outweighs need for programmable input current limit and true disconnect |
| MAX17222ATA+T | Max output 28 V but limited to 1.2 A peak current; no integrated ISO FET; smaller 2 mm × 2 mm TDFN; lacks ILIM pin and OVP clamp | Targeted at ultra-low-power IoT sensors - insufficient for 3 A input-limited loads or 25 V outputs | Consider only for sub-500 mA, space-constrained applications where 25 V output and true disconnect are unnecessary |
Compared with TPS61376RYHR, TPS61088RHLR offers lower BOM cost but sacrifices programmable input current limiting and true load isolation, while MAX17222ATA+T trades output capability and protection for footprint reduction - neither matches the TPS61376RYHR's combination of 23 V input, 25 V output, 3 A programmable input limit, and integrated ISO FET.

FAQ
What is the maximum output voltage supported by the TPS61376RYHR?
The TPS61376RYHR supports an output voltage range of 4.5 V to 25 V, programmable via the FB pin resistor divider. Its output overvoltage protection triggers at 27.5 V (typical), ensuring safe operation even under transient overvoltage conditions. The device maintains regulation accuracy within ±1.5% across temperature and load when configured per datasheet guidelines.
How does the TPS61376RYHR achieve true load disconnection?
The TPS61376RYHR achieves true load disconnection using an integrated 40 mΩ ISO FET between the VP and SW pins. When the EN/UVLO pin is pulled low or VIN falls below UVLO, this FET turns off completely, breaking the conductive path between input and output. This eliminates reverse current flow and ensures zero static power draw from the input source during shutdown - a critical feature for battery-powered systems.
Can the TPS61376RYHR operate with input voltages below 3 V?
No - the TPS61376RYHR has a minimum recommended input voltage of 2.9 V, with UVLO rising threshold at 2.8 V. Operation below 2.9 V risks instability, reduced efficiency, and potential failure to regulate. For sub-3 V applications, TI recommends alternatives like the TPS61099 or TPS61291, which support down to 0.7 V input.
What is the role of the ISEL pin on the TPS61376RYHR?
The ISEL pin on the TPS61376RYHR selects between two peak switching current limit modes: logic high enables 4.5 A (typical), while logic low scales the ISO FET to reduce peak current to 2.5 A (typical) and improve input average current limit accuracy below 750 mA. This dual-mode capability allows optimized performance across both high-current and precision low-current applications.
Does the TPS61376RYHR require external compensation components?
Yes - the TPS61376RYHR requires external loop compensation via the COMP pin. A series RC network (RCOMP and CCOMP) must be connected between COMP and AGND to stabilize the control loop. TI provides design equations and typical values (e.g., RCOMP = 80.6 kΩ, CCOMP = 3.3 nF) in the datasheet for common configurations, and compensation must be re-verified for custom inductor/output capacitor selections.
