Product details
Overview
TPS62362YZHT from Texas Instruments is a 3A synchronous step-down DC-DC converter with I²C interface, differential remote sensing, and DCS-Control™ architecture. It operates from 2.5V–5.5V input, delivers 0.77V–1.4V output in 10mV steps, and supports dynamic voltage scaling for submicron processor cores in smartphones and handheld computers.
For engineers reviewing the TPS62362YZHT datasheet, TPS62362YZHT pinout, TPS62362YZHT application, or TPS62362YZHT equivalent, key selection criteria include its 2.5MHz switching frequency, ±0.5% output voltage accuracy at no load, programmable slew rate via RMP[2:0], thermal shutdown at 150°C, and NanoFree™ 2mm × 2mm CSP-16 package with PGND/AGND separation.
Technical Context
The TPS62362YZHT integrates a high-side P-MOS and low-side N-MOS power stage with RDS(on) of 25–75mΩ and 25–50mΩ respectively, enabling 3A peak current delivery. Its DCS-Control™ architecture combines voltage-mode control with fast transient response through an error amplifier and ramp generator, supporting both forced PWM and auto PFM/PWM modes.
Differential remote sensing (SENSE+/SENSE−) enables precise load regulation (<0.05%/A), while the I²C interface (up to 3.4MHz high-speed mode) allows real-time voltage programming and status monitoring. Dedicated VSEL0/VSEL1 pins provide hardware-based preset transitions for performance/retention mode switching without software intervention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 3A peak, 2.5A continuous - supports burst-mode CPU loads without thermal derating in compact layouts. |
| Input Voltage Range | 2.5V–5.5V - compatible with single-cell Li-ion, Li-polymer, and dual-cell alkaline battery systems. |
| Output Voltage Range | 0.77V–1.4V in 10mV steps - matches core voltage requirements of ARM Cortex-A series and similar processors. |
| Switching Frequency | 2.5MHz typical - enables use of small 0.47µH or 1µH inductors and <25mm² total solution size. |
| Output Accuracy | ±0.5% at no load, VIN = 2.5–5.5V - ensures stable operation of low-voltage digital cores under varying line conditions. |
| I²C Interface Speed | Up to 3.4MHz high-speed mode - permits rapid voltage scaling during DVFS transitions with minimal bus overhead. |
| Thermal Shutdown | 150°C with 20°C hysteresis - protects silicon integrity during sustained overload or poor PCB thermal design. |
Pinout & Package
The TPS62362YZHT uses a 16-bump, 2mm × 2mm NanoFree™ CSP package with exposed PGND pad for thermal dissipation. Pin layout follows a defined 4×4 grid with dedicated analog/digital ground separation and remote sense routing paths.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AVIN | Analog supply input | Provides clean bias for internal analog circuitry; decoupling required near pin to minimize noise coupling into control loop. |
| EN | Enable logic input | Active-high enable with internal pulldown; must be driven to valid logic level to avoid undefined startup behavior. |
| VDD | I²C and register supply | Independent 1.15–3.6V rail for communication interface; UVLO at 0.7–1.1V enables controlled register reset. |
| SCL/SDA | I²C clock/data bidirectional | Supports standard/fast/high-speed modes; requires external pull-ups referenced to VDD, not AVIN or VIN. |
| VSEL0/VSEL1 | Hardware voltage preset select | Two-pin binary encoding for up to four factory-programmed output voltages - enables instant mode switching without I²C transaction. |
| SENSE+/SENSE− | Differential remote sense inputs | Connect directly to load power/ground nodes to cancel IR drop in PCB traces and improve regulation at point-of-load. |
| SW | Switch node | Drives external inductor; requires low-inductance layout and ceramic output capacitor placement adjacent to SW/PGND. |
| PGND/AGND | Power/analog ground | Separate ground returns prevent switching noise from modulating reference or error amplifier performance. |
Key Features
| Feature | Design Value |
|---|---|
| DCS-Control™ architecture | Combines fast transient response (<10µs recovery from 1A–3A load step) with stable regulation across input/output variations. |
| Programmable output slew rate | RMP[2:0] bits set voltage transition speed from 0.25mV/µs to 32mV/µs - prevents excessive inrush current during DVFS transitions. |
| Power save mode for light loads | Reduces quiescent current to 56µA in PFM mode - extends battery life during system idle or retention states. |
| Dedicated hardware VSEL pins | Enables zero-latency voltage changes between four preset outputs - critical for real-time performance mode switching in mobile SoCs. |
| Integrated soft-start | Controls inrush current during startup; eliminates need for external timing capacitor or sequencing 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 |
|---|---|---|---|
| TPS62363YZHT | Wider output range (0.5V–1.77V); same package, pinout, and feature set. | Required for processors needing sub-0.77V core voltages (e.g., advanced 7nm/5nm SoCs). | Select TPS62363YZHT only when minimum output voltage below 0.77V is mandatory; otherwise TPS62362YZHT offers tighter default range and reduced configuration complexity. |
| TPS62361BYZHT | Same 0.5V–1.77V range as TPS62363YZHT but with different factory presets (0.96V/1.40V/1.16V/1.16V). | Optimized for legacy SmartReflex™ implementations requiring specific voltage combinations. | Choose TPS62361BYZHT if existing firmware expects its exact preset sequence; otherwise TPS62362YZHT's 1.23V/1.00V/1.20V/1.10V defaults better match modern DVFS profiles. |
Compared with TPS62363YZHT and TPS62361BYZHT, the TPS62362YZHT provides a narrower, more targeted 0.77V–1.4V output range that simplifies register configuration and reduces risk of accidental undershoot during startup, while retaining identical thermal performance, package compatibility, and I²C command structure.

FAQ
What is the maximum continuous output current supported by the TPS62362YZHT?
The TPS62362YZHT supports 2.5A continuous output current per recommended operating conditions. While it delivers up to 3A peak current, sustained operation above 2.5A may impact device lifetime due to thermal stress; design margins should account for ambient temperature, PCB copper area, and θJA of 94.8°C/W in typical layouts.
Does the TPS62362YZHT require external compensation components?
No, the TPS62362YZHT does not require external compensation components. Its DCS-Control™ architecture integrates all necessary compensation within the IC, enabling stable operation with only a 0.47µH or 1µH inductor and ceramic output capacitors - reducing BOM count and layout complexity.
How does the differential remote sensing function in the TPS62362YZHT improve regulation accuracy?
The TPS62362YZHT uses SENSE+ and SENSE− pins to measure voltage directly at the load terminals, rejecting voltage drop across PCB traces and interconnects. This achieves <0.05%/A load regulation and maintains ±0.5% output accuracy even with 100mΩ of path resistance between the IC and processor core.
Can the TPS62362YZHT operate without I²C communication enabled?
Yes, the TPS62362YZHT can operate without I²C communication. It powers up to a default voltage determined by VSEL0/VSEL1 pin states and supports full functionality-including enable/disable, power-save mode, and hardware preset transitions-using only those two logic inputs and the EN pin.
What thermal protection features are integrated into the TPS62362YZHT?
The TPS62362YZHT includes die temperature early warning at 120°C and thermal shutdown at 150°C with 20°C hysteresis. These features protect against permanent damage during overload, poor heatsinking, or ambient temperature excursions, and allow safe recovery once junction temperature falls below 130°C.
