Product details
Overview
TPS62362YZHR from Texas Instruments is a 3A synchronous step-down DC-DC converter with I²C interface, optimized for battery-powered portable processors. It delivers programmable output voltage from 0.77V to 1.4V in 10mV steps, operates at 2.5MHz switching frequency, supports differential remote sensing, and targets submicron DSP/processor core supplies in smartphones and tablets.
For engineers reviewing the TPS62362YZHR datasheet, TPS62362YZHR pinout, TPS62362YZHR application, or TPS62362YZHR equivalent, key selection criteria include I²C-programmable VOUT range (0.77–1.4V), DCS-Control™ transient response, ±0.5% output accuracy at 1.2V, 2.5MHz fixed-frequency PWM mode, and NanoFree™ 2mm × 2mm CSP-16 package with integrated PGND/AGND separation.
Technical Context
The TPS62362YZHR implements DCS-Control™ architecture combining voltage-mode control with real-time ripple injection for fast transient regulation and precise DC accuracy. Its dual-MOSFET synchronous buck topology integrates high-side (44mΩ typ) and low-side (32mΩ typ) switches, enabling 3A peak current delivery with minimal external components.
It features dedicated hardware pins (VSEL0/VSEL1) for preset voltage transitions and an I²C interface supporting Standard/Fast/High-Speed modes up to 3.4MHz. Differential remote sense (SENSE+/SENSE−) compensates for PCB IR drop, while programmable slew rate (via RMP[2:0]) controls output voltage ramping during dynamic voltage scaling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 3A peak / 2.5A continuous - supports burst-mode processor loads without thermal derating in compact layouts. |
| Input Voltage Range | 2.5V to 5.5V - compatible with single-cell Li-ion, Li-polymer, and USB-powered systems. |
| Output Voltage Range | 0.77V to 1.4V in 10mV steps - matches voltage requirements of ARM Cortex-A/RISC-V cores and LPDDR memory I/O. |
| Switching Frequency | 2.5MHz nominal - enables use of small 0.47µH/1µH inductors and <25mm² total solution size. |
| Output Accuracy | ±0.5% at VOUT = 0.77–1.3V, TJ = 85°C - ensures stable operation of sub-1V logic domains under load and line variation. |
| Quiescent Current | 56µA in PFM mode - extends battery life during processor retention/idle states without sacrificing wake-up speed. |
| Thermal Shutdown | 150°C with 20°C hysteresis - protects silicon integrity during sustained high-current operation in sealed enclosures. |
Pinout & Package
The TPS62362YZHR uses a 16-bump, 2mm × 2mm NanoFree™ CSP package with bottom-side thermal pad (PGND-connected). Pin assignment follows JEDEC MO-220 standard with AVIN, VIN, and PGND separated for optimal analog/digital/power ground isolation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AVIN | Analog supply input | Provides clean bias for internal reference, error amplifier, and I²C circuitry; decoupled separately from power path. |
| VIN | Main power input | Connects to battery or intermediate rail; feeds high-side switch and gate driver; requires local 10µF ceramic capacitor. |
| SW | Switch node | Drives external inductor; requires tight layout to minimize EMI and switching losses; shared across two bumps for current sharing. |
| SENSE+ | Remote sense positive | Connects directly to load VDD pin to compensate for PCB trace resistance; enables ±0.5% regulation at point-of-load. |
| SENSE− | Remote sense negative | Connects directly to load GND pin; completes Kelvin sensing loop; must be routed adjacent to SENSE+ with matched length. |
| SCL/SDA | I²C interface | Supports high-speed mode (3.4MHz) for rapid voltage scaling; VDD-referenced logic (1.15–3.6V) enables direct connection to AP GPIOs. |
| EN | Enable control | Active-high logic input with internal 300kΩ pulldown; allows hardware-controlled power sequencing independent of I²C bus state. |
| VSEL0/VSEL1 | Hardware voltage presets | Select among four factory-programmed VOUT levels (1.23V/1.00V/1.20V/1.10V); bypasses I²C for boot-time or fail-safe operation. |
Key Features
| Feature | Design Value |
|---|---|
| DCS-Control™ architecture | Combines voltage-mode stability with ripple-based transient response - achieves <10µs recovery from 1A load step with <15mV droop. |
| Differential remote sensing | Compensates for up to 50mΩ PCB trace resistance - maintains ±0.5% output accuracy even with 200mm trace lengths. |
| I²C programmable slew rate | RMP[2:0] bits set voltage transition rate from 0.25mV/µs to 32mV/µs - prevents system-level timing violations during DVFS transitions. |
| Power Save Mode (PFM) | Automatically enters discontinuous conduction at light loads - sustains >85% efficiency down to 1mA output current. |
| NanoFree™ packaging | Chip-scale package with no bond wires or leadframe - reduces parasitic inductance by 40% vs. QFN, improving EMI performance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62363YZHR | Wider VOUT range (0.5V–1.77V); same pinout and I²C interface. | Required for sub-0.77V cores (e.g., 0.5V AI accelerators) or higher-voltage I/O rails. | Select when design requires <0.77V or >1.4V output; otherwise TPS62362YZHR offers tighter tolerance over its narrower range. |
| TPS62480RNCR | Higher 4A rating; 2.4MHz switching; no I²C; uses resistor-programmed VOUT. | Suitable for fixed-voltage, high-current applications without DVFS (e.g., baseband processors). | Choose when I²C control is unnecessary and board space allows larger 3mm × 3mm QFN; not drop-in compatible due to different pinout and control scheme. |
Compared with TPS62363YZHR and TPS62480RNCR, the TPS62362YZHR provides optimal balance of I²C programmability, 0.77–1.4V precision targeting modern application processors, and ultra-compact 2mm × 2mm footprint-making it the preferred choice for space-constrained DVFS implementations where voltage granularity and transient response are critical.

FAQ
What is the maximum continuous output current supported by the TPS62362YZHR?
The TPS62362YZHR supports 2.5A continuous output current per recommended operating conditions. While it delivers up to 3A peak current for short durations (e.g., CPU burst loads), sustained operation above 2.5A may impact device lifetime due to thermal stress-TI specifies 2.5A as the continuous rating for reliable long-term operation in typical handheld thermal environments.
Does the TPS62362YZHR require external compensation components?
No, the TPS62362YZHR does not require external compensation components. Its DCS-Control™ architecture embeds all necessary compensation within the IC, enabling stable operation with only a single output capacitor (minimum 10µF ceramic) and inductor-reducing BOM count and layout complexity compared to traditional voltage-mode controllers.
How does the differential remote sensing function in the TPS62362YZHR improve regulation accuracy?
The TPS62362YZHR uses dedicated SENSE+ and SENSE− pins to measure voltage directly at the load terminals, rejecting voltage drops across PCB traces and package parasitics. This Kelvin sensing method maintains ±0.5% output accuracy at the point-of-load-even with 50mΩ total path resistance-critical for sub-1V core rails where 10mV error can cause functional failure.
Can the TPS62362YZHR operate without I²C communication enabled?
Yes, the TPS62362YZHR can operate without I²C. Its VSEL0 and VSEL1 pins allow selection of four factory-programmed output voltages (1.23V, 1.00V, 1.20V, 1.10V) in hardware, enabling full functionality during boot or if the I²C bus is unavailable. The I²C interface is optional for dynamic reconfiguration during runtime.
What thermal metrics define the TPS62362YZHR's junction-to-ambient performance?
The TPS62362YZHR has a θJA of 94.8°C/W under JEDEC-standard high-K board conditions. Its ψJB (junction-to-board characterization parameter) is 57°C/W, indicating strong thermal coupling to the PCB-meaning effective copper pour and thermal vias beneath the PGND pad are essential to maintain TJ ≤125°C at 2.5A continuous load in real-world layouts.
