Product details
Overview
TPS62366AYZHT from Texas Instruments is a 4A 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 0.5V–1.77V output in 10mV steps, and achieves up to 95% efficiency at 4A load. Designed for smartphone application processors requiring dynamic voltage scaling and precise transient regulation.
For engineers reviewing the TPS62366AYZHT datasheet, TPS62366AYZHT pinout, TPS62366AYZHT application, or TPS62366AYZHT equivalent, key selection criteria include I²C-programmable VOUT, ±0.5% DC accuracy over –40°C to 150°C, 2.5MHz switching frequency, integrated power-save mode, and 2mm × 2mm NanoFree™ CSP package with remote sense capability.
Technical Context
The TPS62366AYZHT implements a high-frequency synchronous buck topology with integrated high-side (25–75mΩ) and low-side (25–50mΩ) MOSFETs, controlled by DCS-Control™ architecture that combines voltage-mode control with real-time output impedance compensation. Its dual-loop regulation uses differential SENSE+ and SENSE– inputs to reject PCB IR drop and maintain ±0.5% output accuracy under load transients.
I²C interface supports Standard, Fast, and High-Speed modes (up to 3.4MHz), enabling dynamic voltage transitions with programmable slew rate (0.25–32mV/µs via RMP[2:0]). Hardware VSEL pin allows preset voltage selection without I²C traffic, while EN pin provides logic-controlled enable/disable with internal pull-down resistor (300kΩ).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output current | 4A peak, 2.5A continuous - supports high-performance mobile SoCs during burst loads. |
| Input voltage range | 2.5V–5.5V - compatible with single-cell Li-ion, Li-polymer, and USB-powered systems. |
| Output voltage range | 0.5V–1.77V in 10mV steps - enables fine-grained digital voltage scaling for ARM Cortex-A/R cores. |
| Switching frequency | 2.5MHz typical - allows use of compact 0.47µH or 1µH inductors and <25mm² total solution size. |
| DC output accuracy | ±0.5% (0mA–2.5A, –40°C to 85°C), ±1% (–40°C to 150°C) - ensures stable core voltage under thermal stress. |
| I²C interface speed | Up to 3.4MHz High-Speed mode - reduces VOUT reconfiguration time to sub-10µs for performance state transitions. |
| Thermal protection | 150°C shutdown with 20°C hysteresis - prevents permanent damage during sustained overload or poor airflow. |
Pinout & Package
The TPS62366AYZHT is housed in a 16-bump, 2mm × 2mm NanoFree™ CSP (YZH) package with 0.4mm pitch and exposed thermal pad on bottom. Package dimensions and solder mask layout comply with JEDEC MO-277.
| 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 feedback path. |
| EN | Enable logic input | Active-high enable with internal 300kΩ pulldown; asserts soft-start and disables switching when LOW. |
| VDD | I²C and register supply | 1.15V–3.6V logic rail; must fall below 0.7V to reset internal registers during power sequencing. |
| SCL / SDA | I²C bidirectional bus | Supports 3.4MHz High-Speed mode; requires external pull-ups to VDD, max 400pF bus capacitance. |
| VSEL | Hardware voltage preset select | Logic HIGH/LOW selects factory-programmed VOUT presets (e.g., 1.20V/1.16V for TPS62366A variant). |
| SENSE+ / SENSE– | Differential remote sense inputs | Connect directly to load power/ground nodes to compensate for PCB trace resistance and maintain tight regulation. |
| VIN / PGND / AGND / SW | Main power path terminals | VIN and PGND handle high-current paths; AGND is isolated analog ground; SW drives external inductor. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar DC-DC converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62366BYZHT | Same package and pinout; factory-programmed VOUT presets differ (0.96V/1.40V vs. TPS62366AYZHT's 1.20V/1.16V). | Optimized for SoCs requiring lower base voltage (e.g., 0.96V retention mode) and higher performance voltage (1.40V). | Select TPS62366BYZHT when target processor VOUT profile matches its factory presets; otherwise use A-version with full I²C programming. |
| TPS62400DRCR | 3A rated, 2.25MHz switching, no I²C interface; uses external resistor divider for fixed VOUT; lacks remote sense. | Suitable for cost-sensitive designs where dynamic voltage scaling is not required and ±1% accuracy suffices. | Choose TPS62400DRCR only if I²C control, 4A capability, and differential sensing are unnecessary - avoids over-specification. |
Compared with TPS62366BYZHT, the TPS62366AYZHT offers tighter VOUT presets for mid-range SoC operating points; versus TPS62400DRCR, it delivers 33% higher current, programmability, and precision sensing - critical for modern mobile power architectures.

FAQ
What is the maximum continuous output current supported by the TPS62366AYZHT?
The TPS62366AYZHT supports 2.5A continuous output current across the full operating temperature range (–40°C to 85°C ambient). Its 4A peak rating enables short-duration burst loads typical in smartphone application processors, provided thermal design maintains junction temperature ≤150°C per the θJA = 94.8°C/W specification.
Does the TPS62366AYZHT require external components for basic operation?
Yes - the TPS62366AYZHT requires an external inductor (0.47µH or 1µH), input capacitor (≥10µF), output capacitor (≥10µF), and optional RC network for soft-start timing. The device integrates MOSFETs, compensation, and I²C interface, enabling a total solution size under 25mm² - significantly smaller than discrete controller-based alternatives.
How does the differential remote sensing function in the TPS62366AYZHT improve regulation accuracy?
The TPS62366AYZHT uses dedicated SENSE+ and SENSE– pins to measure voltage directly at the load, rejecting voltage drop across PCB traces and connectors. This maintains ±0.5% DC output accuracy even with up to 50mΩ of series resistance between the IC and load - critical for maintaining SoC stability in compact, high-current layouts.
Can the TPS62366AYZHT operate without I²C communication?
Yes - the TPS62366AYZHT can be configured for fixed-output operation using the hardware VSEL pin to select factory-programmed presets (1.20V and 1.16V for the A-version). I²C is optional for fine-grained adjustment (0.5V–1.77V in 10mV steps) and dynamic slew rate control, but not required for basic enable/disable and regulation.
What thermal metrics apply to the TPS62366AYZHT in its YZH package?
The TPS62366AYZHT in the 2mm × 2mm NanoFree™ YZH package has θJA = 94.8°C/W (JEDEC high-K board), θJCbot = n/a (no exposed thermal pad), and ψJB = 57°C/W. These values indicate strong board-level heat dissipation capability; designers should ensure ≥400mm² of 2-oz copper pour under the package for optimal thermal performance at 2.5A continuous load.
