Product details
Overview
TPS613771RYHR from Texas Instruments is a high-voltage synchronous boost converter IC designed for industrial and appliance power conversion, delivering up to 25 V output from 2.9–23 V input with 6-A peak switching current capability, 1.2-MHz fixed switching frequency, and programmable current limit (1.5–6 A) via external resistor.
For engineers reviewing the TPS613771RYHR datasheet, TPS613771RYHR pinout, TPS613771RYHR application, or TPS613771RYHR equivalent, key selection criteria include its HotRod™ Lite VQFN-13 package, adaptive constant off-time control topology, dual-mode light-load operation (PFM/PWM), integrated 40-mΩ high-side and 50-mΩ low-side MOSFETs, and precise output overvoltage protection at 27.5 V.
Technical Context
The TPS613771RYHR implements an adaptive constant off-time peak current control architecture, enabling quasi-constant-frequency PWM operation under moderate-to-heavy loads while supporting seamless transition to auto PFM or forced PWM modes at light load via the MODE pin. Its internal error amplifier drives external compensation (COMP pin), and it uses separate AGND and PGND pins for noise isolation.
It integrates dual N-channel MOSFETs (40 mΩ high-side, 50 mΩ low-side), supports programmable UVLO via EN/UVLO pin with 0.813-V internal reference and 2-µA hysteresis current, and features cycle-by-cycle overcurrent protection triggered by ILIM-set peak current threshold - all within a thermally enhanced 2.5-mm × 2.0-mm VQFN package with exposed thermal pad.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switching frequency | 1.2 MHz - enables smaller magnetics and reduced EMI filtering requirements vs 650-kHz variants. |
| Input voltage range | 2.9 V to 23 V - supports wide-range industrial inputs including 3.3-V, 5-V, 9-V, 12-V, and 16-V rails. |
| Output voltage range | 4.5 V to 25 V - configurable via FB resistor divider; suitable for 12-V and 24-V system rails. |
| Peak switching current limit | 1.5 A to 6 A - set externally via ILIM-to-AGND resistor; enables scalable power delivery without layout change. |
| Quiescent current | 70 µA typical - minimizes standby power loss in battery-backed or always-on systems. |
| Shutdown current | 1.25 µA maximum - ensures ultra-low leakage during system sleep or fault conditions. |
| Output OVP threshold | 27.5 V typical - protects downstream 24-V loads from overvoltage damage with 0.9-V hysteresis. |
| Thermal shutdown | 150°C rising / 130°C falling - provides robust thermal safety margin for continuous 6-A operation in compact layouts. |
Pinout & Package
TPS613771RYHR is housed in a 2.5-mm × 2.0-mm, 13-pin HotRod™ Lite VQFN package (RYH) with wettable flanks and an exposed thermal pad for enhanced thermal performance in high-power density designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Power input | Main supply input (2.9–23 V); powers internal LDO when >5.5 V, else sourced from VOUT. |
| EN/UVLO | Enable & UVLO input | Logic-enable pin with programmable undervoltage lockout using resistor divider; 0.813-V internal reference. |
| MODE | Light-load mode select | Logic-high = forced PWM (fixed 1.2 MHz); logic-low = auto PFM (efficiency-optimized variable frequency). |
| VSENSE | Output voltage sense | Dedicated high-impedance input for remote sensing; improves regulation accuracy under load transients. |
| VOUT | Power output | Boosted output node (4.5–25 V); connects to output capacitor and load; monitored for OVP. |
| SW | Switching node | Drain of low-side FET / source of high-side FET; requires low-ESR ceramic boot capacitor (0.47–1 µF) to BOOT. |
| PGND | Power ground | High-current return path for SW, VIN, and VOUT; must be routed separately from AGND to minimize noise coupling. |
| FB | Feedback input | Connects to center tap of resistor divider; 1.0-V internal reference enables precise output voltage programming. |
| COMP | Error amplifier output | External compensation node; connects RC/CC network to AGND for loop stability across operating conditions. |
| ILIM | Current limit programming | Resistor-to-AGND sets peak switch current (1.5–6 A); cannot float or tie to VCC. |
| VCC | Internal regulator output | 4.8-V regulated supply for gate drivers; requires ≥1-µF X7R/X5R ceramic capacitor to AGND. |
| AGND | Analog ground | Reference for FB, COMP, ILIM, MODE, EN/UVLO; must connect to PGND at single point near IC. |
| BOOT | High-side gate drive | Bootstrap supply for high-side FET; capacitor between BOOT and SW enables efficient 40-mΩ high-side conduction. |
Key Features
| Feature | Design Value |
|---|---|
| Adaptive constant off-time control | Enables fast transient response with minimal output capacitance and stable operation across wide VIN/VOUT ratios. |
| Programmable peak current limit | 1.5–6 A range via single external resistor - allows one BOM to support multiple output power levels. |
| Dual light-load operating modes | Auto PFM maximizes efficiency down to µA loads; forced PWM eliminates audible noise and EMI variability. |
| Integrated dual MOSFETs | 40-mΩ high-side + 50-mΩ low-side switches - eliminate external FETs and reduce board area vs discrete solutions. |
| Comprehensive protection suite | Output OVP (27.5 V), cycle-by-cycle OCP, thermal shutdown (150°C), and soft-start (4 ms) ensure robust field reliability. |
| HotRod™ Lite VQFN-13 package | 2.5 × 2.0 mm footprint with exposed thermal pad - delivers superior thermal resistance (RθJB = 15.4°C/W) for 6-A operation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS61377RYHR | 650-kHz switching frequency; identical pinout, package, and feature set except frequency and internal timing circuitry. | Better suited for EMI-sensitive environments where lower frequency simplifies filtering; slightly larger inductors required. | Select TPS61377RYHR when board space permits larger magnetics and lower EMI priority outweighs efficiency gains at light load. |
| LM61480RQWR | 4.5–36-V input, 1.5–22-V output, 8-A capability; uses current-mode control; 2.5-mm × 3.0-mm VQFN-16 package. | Higher input voltage ceiling and output current rating; lacks VSENSE pin and programmable OVP threshold. | Choose LM61480RQWR only if input exceeds 23 V or peak load exceeds 6 A; requires PCB redesign due to different pin count and layout. |

FAQ
What is the switching frequency of the TPS613771RYHR?
The TPS613771RYHR operates at a fixed 1.2 MHz switching frequency, as confirmed in the device comparison table and electrical characteristics section of the official datasheet. This higher frequency versus the 650-kHz TPS61377 variant enables smaller external inductors and capacitors, reducing overall solution size and easing EMI filter design. The frequency remains stable across input and output voltage ranges and load conditions in forced PWM mode.
How is the peak current limit programmed on the TPS613771RYHR?
The peak switching current limit of the TPS613771RYHR is set by connecting an external resistor between the ILIM pin and AGND. Using the formula IPEAK = 0.54 V × 160 kΩ / RLIM, values from 1.5 A (RLIM = 57.6 kΩ) to 6 A (RLIM = 14.4 kΩ) are achievable. The ILIM pin must never be left floating or tied to VCC, and resistor tolerance directly impacts current limit accuracy.
Does the TPS613771RYHR support remote output voltage sensing?
Yes, the TPS613771RYHR includes a dedicated VSENSE pin for remote output voltage sensing, distinct from the FB pin used for feedback. This allows direct connection to the load point, compensating for IR drop across PCB traces and connectors. When enabled, VSENSE overrides the FB pin for regulation, improving output voltage accuracy under dynamic load conditions.
What protection features does the TPS613771RYHR include?
The TPS613771RYHR integrates output overvoltage protection (OVP) with 27.5-V typical threshold and 0.9-V hysteresis, cycle-by-cycle overcurrent protection triggered by the ILIM-set peak current, thermal shutdown at 150°C (with 130°C restart hysteresis), and soft-start (4-ms ramp). These features operate independently of external components and require no configuration.
Can the TPS613771RYHR operate with input voltages below 3 V?
No - the absolute minimum recommended input voltage for the TPS613771RYHR is 2.9 V, per the Recommended Operating Conditions table. Operation below this level risks failure to start or erratic behavior due to insufficient headroom for the internal LDO and gate drivers. The UVLO threshold is 2.8 V (rising), with 200-mV hysteresis, ensuring reliable enable/disable sequencing.
