Product details
Overview
TPS62366BYZHT 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 supports dynamic voltage scaling for application processors in smartphones and tablets.
For engineers reviewing the TPS62366BYZHT datasheet, TPS62366BYZHT pinout, TPS62366BYZHT application, or TPS62366BYZHT equivalent, key selection criteria include its 2.5MHz switching frequency, ±0.5% output voltage accuracy (forced PWM, no load), programmable slew rate, thermal shutdown at 150°C, and NanoFree™ 2mm × 2mm CSP-16 package.
Technical Context
The TPS62366BYZHT integrates high-side and low-side MOSFETs (RDS(on) = 25–75mΩ and 25–50mΩ respectively) with integrated gate drivers and DCS-Control™ feedback loop for fast transient response. Its dual-mode operation (PFM for light loads, forced PWM for regulation stability) enables high efficiency across 1mA–4A output current range.
Differential remote sensing (SENSE+/SENSE−) compensates for PCB IR drop, while I²C interface (up to 3.4MHz high-speed mode) allows real-time voltage programming and status monitoring. The device implements soft-start, programmable voltage transition slew rate, over-temperature protection, and input UVLO with hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 4A peak, 2.5A continuous - supports high-performance mobile SoCs under burst load conditions. |
| 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 precise digital voltage scaling for ARM Cortex-A series and DSP cores. |
| Switching Frequency | 2.5MHz typical - allows use of small 0.47µH/1µH inductors and <25mm² total solution size. |
| Output Voltage Accuracy | ±0.5% (no load, forced PWM, TJ = 25°C) - ensures core logic meets tight VDD tolerance requirements. |

Pinout & Package
TPS62366BYZHT uses a 16-bump, 2mm × 2mm NanoFree™ chip-scale package (CSP) with 0.4mm ball pitch and exposed thermal pad on bottom side. Package marking "YZH" identifies the variant; "T" suffix denotes 250-piece tape-and-reel packaging.
| 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 enable; internal 300kΩ pulldown allows single-resistor pull-up for power sequencing control. |
| VDD | I²C and register supply | Must be powered before I²C communication; UVLO at 0.7–1.1V enables safe register reset during brownout. |
| SCL / SDA | I²C serial interface | Supports standard/fast/high-speed modes; requires external pull-ups; CB ≤ 400pF for 3.4MHz operation. |
| VSEL | Hardware voltage preset select | Two-state logic input selects factory-programmed VOUT presets (0.96V/1.40V for TPS62366B). |
| SW | Switch node | Connects to external inductor; high di/dt node requiring short, low-inductance routing and ground plane clearance. |
| SENSE+ / SENSE− | Differential remote sense inputs | Must connect directly to load power/ground nodes to cancel PCB trace resistance error; 2.2MΩ input impedance. |
| VIN | Main power input | Supplies high-current path to internal FETs; requires low-ESR bulk capacitance (≥10µF) and local 0.1µF ceramic. |
| PGND / AGND | Power and analog ground | Separate ground pins minimize noise coupling; PGND handles high-switching currents; AGND routes sensitive analog returns. |
Key Features
| Feature | Design Value |
|---|---|
| DCS-Control™ architecture | Combines voltage-mode control with feed-forward compensation to achieve <10µs load transient recovery and ±0.5% DC regulation. |

| Programmable voltage transition slew rate | Configurable via RAMP[2:0] bits (0.25–32mV/µs) to prevent overshoot/undershoot during DVFS transitions. |
| Power Save Mode (PFM) | Reduces quiescent current to 56µA at light loads while maintaining regulation, extending battery runtime in idle states. |
| Integrated thermal early warning | Digital flag asserts at 120°C junction temperature, enabling system-level thermal management before shutdown at 150°C. |
| NanoFree™ CSP package | Eliminates wirebonds and mold compound; 0.4mm pitch enables direct die attachment to PCB for superior thermal performance (θJA = 94.8°C/W). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar DC-DC converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62366AYZHT | Same package and pinout; factory presets at 1.20V/1.16V instead of 0.96V/1.40V; identical electrical specs. | Preferred for systems requiring lower nominal core voltages (e.g., Cortex-M7 at 1.15V) without I²C reprogramming. | Select TPS62366AYZHT when fixed 1.20V/1.16V presets align with target SoC operating points and I²C control is unused. |
| TPS62400DRVR | 3A output, 2.25MHz switching, 3mm × 3mm WSON package; lacks I²C interface but includes PWRGOOD and MODE pins. | Targeted at cost-sensitive, non-DVFS applications where fixed output or resistor-programmed voltage suffices. | Choose TPS62400DRVR for simpler, lower-cost point-of-load designs without dynamic voltage scaling requirements. |
Compared with TPS62366AYZHT, the TPS62366BYZHT offers higher flexibility for asymmetric DVFS profiles (e.g., 0.96V for LITTLE cluster, 1.40V for big cluster); versus TPS62400DRVR, it trades pin count and interface complexity for precision, programmability, and smaller footprint.

FAQ
What is the maximum continuous output current supported by the TPS62366BYZHT?
The TPS62366BYZHT supports 2.5A continuous output current under recommended operating conditions (TA ≤ 85°C, proper PCB thermal design). Its 4A peak rating accommodates short-duration CPU/GPU burst loads typical in mobile applications, provided thermal limits are observed.
Does the TPS62366BYZHT require external compensation components?
No, the TPS62366BYZHT uses TI's DCS-Control™ architecture with internal compensation. It operates stably with only the required input/output capacitors (10µF input, ≥22µF output) and a single external inductor (0.47µH or 1µH), eliminating loop compensation design effort.
How does the TPS62366BYZHT handle thermal management during sustained high-load operation?
The TPS62366BYZHT integrates die temperature early warning (120°C) and thermal shutdown (150°C with 20°C hysteresis). Its NanoFree™ CSP package provides low θJA (94.8°C/W) and θJB (60°C/W), enabling effective heat transfer to the PCB when using appropriate copper pour and vias beneath the exposed thermal pad.
Can the TPS62366BYZHT operate without I²C communication enabled?
Yes. The TPS62366BYZHT defaults to factory-programmed VOUT presets (0.96V and 1.40V for TPS62366B) selected via the VSEL pin. I²C is optional for dynamic reprogramming; all protection features (UVLO, OCP, thermal shutdown) remain fully active without I²C initialization.
What is the minimum recommended output capacitance for stable operation of the TPS62366BYZHT?
The TPS62366BYZHT requires ≥22µF total output capacitance for stable DCS-Control™ operation. This is typically achieved with three 10µF X5R/X7R ceramic capacitors (3×10µF = 30µF) placed close to the device, ensuring low ESR and sufficient ripple current rating for 4A peak loads.
