Product details
Overview
TPS631013YBGR from Texas Instruments is a 1.6V–5.5V input, I²C-programmable buck-boost converter in wafer chip-scale package (WCSP), delivering up to 1.5A output at 3.3V with 2MHz fixed-frequency operation, 8μA quiescent current, and seamless mode transition between buck, boost, and 3-cycle buck-boost for TWS earbuds and sensor pre-regulation.
For engineers reviewing the TPS631013YBGR datasheet, TPS631013YBGR pinout, TPS631013YBGR application, or TPS631013YBGR equivalent, key selection criteria include its default-enabled EN state, 0x2A I²C address, 1.803mm × 0.905mm WCSP footprint, reverse-current capability in FPWM mode, and programmable VOUT (1.0–5.5V in 25mV steps) for dynamic voltage scaling in space-constrained portable systems.
Technical Context
This device uses constant-frequency peak-current-mode control with three defined operating modes-buck, boost, and 3-cycle buck-boost-triggered by VIN/VOUT ratio thresholds to minimize output ripple during transitions. Its architecture supports forward and reverse current flow, start-up into pre-biased outputs, and true shutdown with load disconnection.
Internal protection includes overvoltage (5.55–5.95V on VOUT), thermal shutdown (160°C), short-circuit hiccup (9ms on / 22ms off), and input overvoltage lockout (VT+(IVP) = 5.55–5.95V). I²C interface supports Standard (100kHz), Fast (400kHz), and Fast-mode Plus (1MHz) protocols with 7-bit address 0x2A.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 1.6V to 5.5V - supports single-cell Li-ion, Li-poly, or multi-alkaline battery inputs without external LDO pre-regulation |
| Output Voltage Range | 1.0V to 5.5V adjustable in 25mV steps via I²C - enables precise DVS for SoC core rails or sensor biasing |
| Max Output Current | 1.5A at VIN ≥ 2.7V, VOUT = 3.3V - sufficient for dual-core microcontrollers or high-resolution image sensors |
| Switching Frequency | 1.8–2.2MHz typical - allows use of ultra-small 1µH inductors and compact ceramic capacitors |
| Quiescent Current | 8μA into VOUT - extends battery life in always-on wearable standby modes |
| I²C Address | 0x2A (7-bit) - fixed and distinct from TPS631012 (also 0x2A) but differentiated by default CONVERTER_EN state |
| EN Default State | CONVERTER_EN = 1 - device powers up enabled without host firmware initialization |
Pinout & Package
TPS631013YBGR uses an 8-pin wafer chip-scale package (YBG) measuring 1.803mm × 0.905mm with bottom-side solder bumps. The package is optimized for minimal PCB area and thermal performance (RΘJB = 43.9°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Power Input | Main supply rail input; UVLO active at 1.4–1.599V with 99mV hysteresis |
| EN | Digital Enable | Active-high logic input; default internal CONVERTER_EN = 1 ensures immediate operation after power-up |
| LX1 | Buck Switch Node | Connects to inductor's buck-stage switching node; Q1 rDS(on) = 45mΩ |
| SDA | I²C Data | Open-drain bidirectional data line; requires external pull-up to I²C bus voltage |
| LX2 | Boost Switch Node | Connects to inductor's boost-stage switching node; Q2 rDS(on) = 50mΩ |
| GND | Power Ground | Primary return path for power stage and IC ground; must be low-impedance plane |
| VOUT | Regulated Output | Delivers programmable output; supports active discharge when EN = low |
| SCL | I²C Clock | Open-drain clock input; synchronizes register reads/writes; supports up to 1MHz Fast-mode Plus |
Key Features
| Feature | Design Value |
|---|---|
| Seamless Buck/Boost/Buck-Boost Mode Transition | Defined duty-cycle thresholds prevent mode toggling and reduce output ripple during VIN ≈ VOUT operation |
| Programmable Dynamic Voltage Scaling (DVS) | VOUT slew rate configurable at 0.4 V/ms (slow) or 7.2 V/ms (fast) for controlled SoC voltage ramping |
| Reverse Current Operation | Supported in FPWM mode only - enables bidirectional power flow for battery backup or power multiplexing |
| True Shutdown with Load Disconnection | Internal switches isolate VOUT from LX1/LX2 and activate active discharge - eliminates floating output states |
| Short-Circuit Hiccup Protection | Configurable via EN_SCP bit; cycles 9ms on / 22ms off until fault clears - prevents thermal runaway under sustained overload |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buck-boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS631012YBGR | Identical electrical specs and pinout; differs only in default CONVERTER_EN = 0 and same I²C address 0x2A | Requires host firmware to assert CONVERTER_EN before output activation - unsuitable for "power-on-ready" systems | Select TPS631012YBGR only when deterministic power sequencing mandates explicit enable control |
| TPS63802YFFR | Higher 2.5A peak switch current, 1.8V–5.5V input, no I²C interface, fixed 3.3V output option | Lacks programmability and reverse-current support; suited for cost-sensitive, fixed-output applications | Choose TPS63802YFFR when VOUT is static and I²C overhead is unnecessary - saves BOM and firmware complexity |
Compared with TPS631012YBGR, TPS631013YBGR eliminates boot-time delay by powering up enabled; versus TPS63802YFFR, it trades fixed-output simplicity for full I²C configurability, enabling adaptive power management in resource-constrained wearables and IoT edge nodes.

FAQ
What is the default enable behavior of the TPS631013YBGR at power-up?
The TPS631013YBGR has CONVERTER_EN = 1 by default, meaning the device powers up enabled and begins regulation immediately once VIN exceeds the UVLO rising threshold (1.5–1.599V). This eliminates the need for host processor intervention to activate the output, making it ideal for plug-and-play portable devices where fast power-on response is critical. The EN pin remains functional for hardware-controlled shutdown.
Does the TPS631013YBGR support reverse current flow from VOUT to VIN?
Yes, the TPS631013YBGR supports reverse current operation - current flowing from VOUT to VIN - but only when forced PWM (FPWM) mode is active. This capability is independent of VIN/VOUT ratio and functions in all operating modes (buck, boost, buck-boost). It enables use cases like power multiplexing or battery backup paths, provided the system design accounts for the active discharge circuitry during disable events.
What I²C addressing and speed modes does the TPS631013YBGR support?
The TPS631013YBGR implements a standard 7-bit I²C interface with fixed target address 0x2A. It supports Standard-mode (100kHz), Fast-mode (400kHz), and Fast-mode Plus (1MHz) clock frequencies. Pull-up resistors on SDA and SCL are required per I²C bus specifications. Register writes persist as long as VIN remains above the POR threshold (1.25–1.65V), ensuring configuration retention across brief input dips.
How does the TPS631013YBGR handle start-up into a pre-biased output?
The TPS631013YBGR supports start-up into pre-biased outputs without damaging external components or causing large inrush currents. During such events, the controller monitors the output voltage relative to the target and adjusts the soft-start ramp accordingly - accelerating recovery if VOUT is already near regulation. This behavior is inherent to the peak-current-mode architecture and requires no additional external circuitry, simplifying design for systems with shared power rails.
What thermal protection features are built into the TPS631013YBGR?
The TPS631013YBGR integrates thermal shutdown protection that disables the power stage when junction temperature exceeds 160°C (typical), with 25°C hysteresis. Once temperature falls below ~135°C, normal operation resumes automatically. This protection operates independently of I²C control and is active in all functional modes. The YBG package's RΘJB = 43.9°C/W enables effective heat transfer to the PCB, supporting continuous 1.5A operation in properly laid-out 2-layer boards.
