Product details
Overview
TPS62363YZHT from Texas Instruments is a 3A synchronous step-down DC-DC converter with I²C interface, remote differential sensing, and DCS-Control™ architecture. It operates from 2.5V–5.5V input, delivers 0.5V–1.77V output in 10mV steps, and supports dynamic voltage scaling for submicron processor cores in smartphones and tablets.
For engineers reviewing the TPS62363YZHT datasheet, TPS62363YZHT pinout, TPS62363YZHT application, or TPS62363YZHT equivalent, key selection criteria include its 2.5MHz switching frequency, ±0.5% output voltage accuracy over temperature, programmable slew rate, and NanoFree™ 2mm × 2mm CSP-16 package with integrated PGND/AGND separation.
Technical Context
The TPS62363YZHT implements a high-frequency synchronous buck topology with integrated high-side (25–75mΩ) and low-side (25–50mΩ) MOSFETs, enabling up to 3A peak output current. Its DCS-Control™ architecture combines voltage-mode control with real-time feedback from differential remote sense inputs (SENSE+, SENSE−) to achieve fast transient response and precise DC regulation.
Control is delivered via an I²C-compatible interface supporting standard/fast/high-speed modes (up to 3.4MHz), while dedicated hardware pins (VSEL0/VSEL1) enable direct voltage preset selection without software intervention. The device includes soft-start, programmable ramp rate (0.25–32mV/µs), thermal shutdown (150°C), and input UVLO with hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 3A peak, 2.5A continuous - supports high-performance mobile SoC burst loads without derating. |
| Input Voltage Range | 2.5V to 5.5V - compatible with single-cell Li-ion, Li-polymer, and USB-powered systems. |
| Output Voltage Range | 0.5V to 1.77V in 10mV steps - enables fine-grained dynamic voltage scaling for ARM Cortex-A/R processors. |
| Switching Frequency | 2.5MHz typical - allows use of compact 0.47µH or 1µH inductors and <25mm² total solution size. |
| Output Accuracy | ±0.5% at TJ = 85°C - ensures stable core voltage under thermal stress in thin-profile handhelds. |
| I²C Interface | High-speed mode up to 3.4MHz - enables rapid voltage transitions during DVFS state changes. |
| Thermal Protection | 150°C shutdown with 20°C hysteresis - prevents permanent damage during sustained overload or poor PCB thermal design. |
Pinout & Package
The TPS62363YZHT is housed in a 2mm × 2mm, 16-bump NanoFree™ CSP (YZH) package with exposed thermal pad on bottom side. Package dimensions are 2.0mm × 2.0mm × 0.62mm (max height), with 0.4mm pitch bump array and solder mask defined pads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AVIN | Analog supply input | Provides clean bias for internal analog circuits; decoupling required near pin to minimize noise coupling into control loop. |
| EN | Enable logic input | Active-high digital control; internal 300kΩ pulldown allows default disable if left floating. |
| VDD | I²C logic supply | Separate 1.15–3.6V rail powers I²C interface and registers; must fall below 0.92V to reset configuration. |
| SCL / SDA | I²C bus interface | Supports high-speed mode (3.4MHz); requires external pull-ups to VDD, not AVIN or VIN. |
| VSEL0 / VSEL1 | Hardware voltage preset select | Four combinations set factory-programmed output voltages (e.g., 1.20V, 1.36V, 1.50V, 1.00V) without I²C transaction. |
| SENSE+ / SENSE− | Differential remote sense inputs | Connect directly to load power/ground nodes to compensate for PCB IR drop; input resistance 2.2MΩ. |
| VIN / PGND / AGND / SW | Main power path | VIN and PGND handle high-current switching; AGND is isolated analog ground; SW connects to external inductor. |
Key Features
| Feature | Design Value |
|---|---|
| DCS-Control™ architecture | Combines fast transient response (<10µs settling) with ±0.5% DC accuracy across line/load/temperature - eliminates need for external compensation. |
| Programmable output voltage slew rate | Configurable via RMP[2:0] bits (000–111) from 0.25mV/µs to 32mV/µs - prevents overshoot/undershoot during DVFS transitions. |
| Dedicated hardware voltage presets | VSEL0/VSEL1 pins provide four fixed output voltages (1.20V, 1.36V, 1.50V, 1.00V) - enables instant performance/retention mode switching without firmware overhead. |
| Low quiescent current in PFM mode | 56µA typical at no load - extends battery life in smartphone standby states without sacrificing light-load efficiency. |
| NanoFree™ CSP-16 package | 2mm × 2mm footprint with 0.4mm pitch - reduces board area by >40% vs. QFN alternatives while maintaining thermal performance (θJA = 94.8°C/W). |

FAQ
What is the maximum continuous output current supported by the TPS62363YZHT?
The TPS62363YZHT supports 2.5A continuous output current per recommended operating conditions. While it delivers up to 3A peak current for short durations aligned with processor burst loads, sustained operation above 2.5A may impact device lifetime due to thermal stress; thermal derating must be applied based on θJA (94.8°C/W) and ambient conditions.
How does the TPS62363YZHT achieve precise output voltage regulation under varying load conditions?
The TPS62363YZHT achieves precise regulation using differential remote sensing (SENSE+, SENSE−) combined with DCS-Control™ architecture. This closed-loop system measures voltage directly at the load, compensating for PCB trace resistance, and dynamically adjusts PWM duty cycle with sub-10µs response to load transients - ensuring ±0.5% DC accuracy and <1% AC deviation even at 3A step changes.
Can the TPS62363YZHT operate without an I²C interface enabled?
Yes, the TPS62363YZHT can operate without I²C by using hardware voltage selection pins VSEL0 and VSEL1. These inputs allow selection of one of four factory-programmed output voltages (1.20V, 1.36V, 1.50V, 1.00V) independently of the I²C bus. The I²C interface remains optional for dynamic reconfiguration, while basic functionality is fully operational with only EN and power connections.
What thermal management considerations apply to the TPS62363YZHT in a 2mm × 2mm CSP package?
The TPS62363YZHT's NanoFree™ YZH package has a junction-to-board thermal resistance (θJB) of 60°C/W and requires proper PCB thermal vias under the exposed die pad. For 2.5A continuous operation at 85°C ambient, minimum recommended copper area is 100mm² with ≥6 thermal vias (0.3mm diameter) connecting to inner ground planes to maintain TJ ≤125°C per datasheet limits.
Does the TPS62363YZHT support power-save mode, and how does it affect light-load efficiency?
Yes, the TPS62363YZHT automatically enters power-save mode (PFM) at light loads, reducing quiescent current to 56µA typical. This mode maintains high efficiency down to 1mA output current by skipping switch cycles while preserving regulation - achieving >85% efficiency at 10mA/1.2V, critical for extending standby time in always-on mobile devices.
