Product details
Overview
TPS62360YZHT from Texas Instruments is a 3A synchronous step-down DC-DC converter with I²C interface, optimized for smartphone and handheld processor core supplies. It operates from 2.5V–5.5V input, delivers 0.77V–1.4V output in 10mV steps, features DCS-Control™ architecture, differential remote sensing, and 2.5MHz switching frequency for compact filter design.
For engineers reviewing the TPS62360YZHT datasheet, TPS62360YZHT pinout, TPS62360YZHT application, or TPS62360YZHT equivalent, this page provides verified technical context, validated pin functions, confirmed I²C timing compliance (up to 3.4 MHz), exact package mapping to 16-bump NanoFree™ CSP (2mm × 2mm), and real-world voltage ramp control behavior across load transitions.
Technical Context
The TPS62360YZHT integrates a high-side P-MOS and low-side N-MOS power stage with RDS(on) of 25–75 mΩ and 25–50 mΩ respectively, enabling 3A peak current delivery. Its DCS-Control™ architecture combines voltage-mode error amplification with direct control of the ramp signal for fast transient response and precise DC regulation.
Differential remote sense inputs (SENSE+, SENSE−) enable accurate load-point regulation independent of PCB IR drop, while programmable slew rate (via RMP[2:0]) supports controlled voltage transitions during dynamic voltage scaling-critical for ARM Cortex-A series and TI OMAP processors requiring SmartReflex™ compliance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 3A peak, 2.5A continuous - supports burst-mode CPU loads without thermal derating in handheld form factors. |
| Input Voltage Range | 2.5V–5.5V - compatible with single-cell Li-ion (3.0–4.2V), Li-polymer, and dual-cell alkaline systems. |
| Output Voltage Range | 0.77V–1.4V in 10mV steps - matches standard core voltage rails for sub-45nm mobile SoCs (e.g., TI OMAP4, Qualcomm Snapdragon S4). |
| Switching Frequency | 2.5MHz typical - enables use of ≤1µH inductors and <10µF ceramic output capacitance for <25mm² total solution size. |
| I²C Interface | High-speed mode up to 3.4MHz - allows rapid voltage updates during DVFS transitions without interrupting processor execution. |
| Remote Sensing | Differential SENSE+ / SENSE− - eliminates PCB trace resistance impact on output accuracy, maintaining ±0.5% regulation at load. |
| Thermal Protection | 150°C shutdown with 20°C hysteresis - prevents permanent damage during sustained 3A operation in thermally constrained modules. |
Pinout & Package
TPS62360YZHT uses a 16-bump, 2mm × 2mm NanoFree™ chip-scale package (CSP) with bottom-side solder bumps. Thermal performance is characterized by θJA = 94.8°C/W and ψJB = 57°C/W on JEDEC-standard high-K board.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AVIN | Analog supply input | Provides clean bias for internal analog circuits; decoupling required near pin to suppress noise coupling into feedback path. |
| EN | Enable logic input | Active-high digital control; internal 300kΩ pulldown ensures safe shutdown if left floating during boot. |
| VDD | I²C logic supply | Must be ≥1.15V for reliable I²C communication; UVLO threshold at 0.92V ensures register reset on brownout. |
| SCL/SDA | I²C bidirectional bus | Supports Fast Mode (400kHz) and High-Speed Mode (3.4MHz); requires external pull-ups referenced to VDD. |
| VSEL0/VSEL1 | Hardware voltage preset select | Allow four factory-programmed output voltages (e.g., 1.40V, 1.00V, 1.40V, 1.10V) without I²C interaction - useful for boot-time configuration. |
| SENSE+/SENSE− | Differential remote sense | Must connect directly to load power/ground nodes; 2.2MΩ input impedance minimizes current draw from sense traces. |
| VIN/PGND/AGND | Main power and ground paths | Separate PGND (power ground) and AGND (analog ground) pins reduce switching noise injection into feedback circuitry. |
| SW | Switch node | Connects to external inductor; high dv/dt requires tight layout and minimized loop area to limit EMI. |
Key Features
| Feature | Design Value |
|---|---|
| DCS-Control™ architecture | Combines fast transient response (<10µs settling for 1A load step) with stable regulation across line/load variations - eliminates need for external compensation. |
| Programmable voltage ramp rate | Eight selectable slew rates (0.25–32 mV/µs via RMP[2:0]) enable precise control of dV/dt during DVFS transitions to avoid supply-induced timing violations. |
| Power Save Mode (PSM) | Extends light-load efficiency (≥85% at 1mA) by entering pulse-frequency modulation - critical for standby battery life in always-on mobile subsystems. |
| Integrated soft-start | Internal 1ms startup time (tStart) with monotonic VOUT rise prevents inrush current and avoids false resets in downstream logic. |
| Robust protection suite | Includes over-temperature shutdown (150°C), input UVLO (2.45V AVIN trip), and current limiting (3.6A typical) - reduces need for external fault management circuitry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar DC-DC converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62362YZHT | Same package and pinout; identical 0.77V–1.4V output range but different factory presets (1.23V/1.00V/1.20V/1.10V vs. TPS62360's 1.40V/1.00V/1.40V/1.10V). | Optimized for SoCs requiring lower default boot voltage; no change in DVFS capability or I²C functionality. | Select when initial boot voltage must be 1.23V instead of 1.40V - preserves PCB layout and firmware compatibility. |
| TPS62361BYZHT | Same package and pinout; wider 0.5V–1.77V output range (10mV steps) and different factory presets (0.96V/1.40V/1.16V/1.16V). | Required for ultra-low-voltage cores (e.g., ARM Cortex-M4 @ 0.9V) or heterogeneous SoCs needing extended DVFS headroom. | Choose when system requires sub-0.77V operation or >1.4V upper limit - retains all control features and thermal specs. |
Compared with TPS62362YZHT and TPS62361BYZHT, the TPS62360YZHT offers the highest factory-set boot voltage (1.40V) within its 0.77V–1.4V range, making it optimal for performance-critical mobile SoCs where maximum initial clock speed is prioritized before software-initiated DVFS.

FAQ
What is the recommended input capacitor for TPS62360YZHT?
The TPS62360YZHT datasheet specifies a minimum 10µF X5R/X7R ceramic capacitor at the VIN pin, placed as close as possible to the device. This value ensures stable operation across the 2.5V–5.5V input range and suppresses high-frequency switching noise. Larger values (e.g., 22µF) improve line transient response but are not required for basic functionality. The capacitor must have low ESL and be rated for ≥6.3V DC.
Does TPS62360YZHT support true hardware-based voltage selection without I²C?
Yes, TPS62360YZHT supports hardware-based voltage selection using the VSEL0 and VSEL1 pins. These inputs allow selection among four predefined output voltages (1.40V, 1.00V, 1.40V, 1.10V) without I²C communication. Each combination of VSEL0/VSEL1 logic levels maps to a specific register setting stored in nonvolatile memory, enabling boot-time configuration independent of host processor initialization.
What is the thermal performance of TPS62360YZHT under 3A continuous load?
Under 3A continuous load at TA = 85°C, the TPS62360YZHT junction temperature reaches approximately 122°C based on θJA = 94.8°C/W and typical power dissipation. This remains below the 125°C maximum operating junction temperature specified for continuous operation. For sustained 3A use, PCB copper area and airflow should be optimized; thermal derating is recommended above 85°C ambient to maintain reliability per TI's lifetime guidelines.
How does the DCS-Control™ architecture in TPS62360YZHT differ from conventional voltage-mode control?
The DCS-Control™ architecture in TPS62360YZHT integrates a voltage-mode error amplifier with direct control of the internal ramp generator, enabling faster transient response (<10µs) and tighter DC regulation (±0.5%) without external compensation components. Unlike traditional voltage-mode controllers requiring RC networks for stability, DCS-Control™ uses the switch-node waveform itself as part of the feedback loop, eliminating phase-margin tuning and improving robustness across component tolerances and temperature.
Can TPS62360YZHT operate with only the AVIN supply, or is VIN mandatory?
VIN is mandatory for TPS62360YZHT operation - it supplies the power stage and internal LDOs. AVIN is a separate analog supply that powers the bandgap reference, error amplifier, and I²C interface; it must be present and ≥2.5V for proper regulation and communication. Both VIN and AVIN must be powered simultaneously; operation with AVIN only (or VIN only) is undefined and will result in malfunction or shutdown.
