Product details
Overview
TPS62366AYZHR from Texas Instruments is a 4A synchronous step-down DC-DC converter in a 2mm × 2mm NanoFree™ CSP package, supporting 2.5V–5.5V input and programmable 0.5V–1.77V output via I²C interface with 10mV steps. It features DCS-Control™ architecture, differential remote sensing, and operates at 2.5MHz for smartphone processor core power delivery.
For engineers reviewing the TPS62366AYZHR datasheet, TPS62366AYZHR pinout, TPS62366AYZHR application, or TPS62366AYZHR equivalent, key selection criteria include I²C-programmable voltage scaling, ±0.5% output accuracy over temperature, 2.5MHz switching frequency, differential remote sense capability, and thermal shutdown at 150°C.
Technical Context
The TPS62366AYZHR implements a high-frequency synchronous buck topology with integrated high-side (25–75 mΩ) and low-side (25–50 mΩ) MOSFETs, controlled by DCS-Control™ architecture combining voltage-mode control with real-time ripple-based feedback for fast transient response. Its dual-path sensing (SENSE+ and SENSE−) enables precise load regulation independent of PCB trace resistance.
I²C interface supports Standard, Fast, and High-Speed modes (up to 3.4 MHz), enabling dynamic voltage scaling during processor performance state transitions. Dedicated VSEL pin allows hardware-triggered preset voltage changes without host intervention, while RAMP[2:0] register controls slew rate from 0.25 to 32 mV/µs.

FAQ
What is the maximum continuous output current supported by the TPS62366AYZHR?
TPS62366AYZHR supports a continuous output current of 2.5A per the recommended operating conditions. Its peak output current capability is rated at 4A, enabling short-duration bursts required during processor performance state transitions. The device maintains thermal stability under these conditions due to its NanoFree™ package and junction-to-board thermal resistance of 60°C/W.
Does the TPS62366AYZHR support true remote voltage sensing?
Yes, the TPS62366AYZHR implements true differential remote sensing using dedicated SENSE+ and SENSE− pins. These inputs connect directly to the load's power and ground nodes, enabling the device to compensate for voltage drop across PCB traces and deliver ±0.5% output accuracy regardless of trace resistance-critical for maintaining core voltage integrity in dense mobile layouts.
How does the DCS-Control™ architecture in the TPS62366AYZHR improve transient response?
The DCS-Control™ architecture in the TPS62366AYZHR combines voltage-mode control with real-time detection of inductor current ripple, enabling sub-10µs transient response to load steps. This eliminates the need for external compensation components and ensures stable regulation with low-ESR ceramic capacitors, making it ideal for rapidly changing processor core loads.
Can the TPS62366AYZHR operate without an I²C host controller?
Yes, the TPS62366AYZHR can operate without an I²C host controller. Its VSEL pin allows selection of two factory-programmed output voltage presets (1.20V and 1.16V for the 'A' variant), enabling standalone operation. I²C is optional for fine-grained 10mV-step programming and dynamic voltage scaling beyond the preset values.
What thermal protection features are integrated into the TPS62366AYZHR?
The TPS62366AYZHR integrates die temperature early warning at 120°C and thermal shutdown at 150°C with 20°C hysteresis. These protections are implemented entirely within the IC and do not require external circuitry. The device also specifies absolute maximum junction temperature of 150°C and provides thermal metrics including θJA = 94.8°C/W for system-level thermal design.
