Texas Instruments TPS62360YZHR

Overview

TPS62360YZHR from Texas Instruments is a 3A synchronous step-down DC-DC converter in a 2mm × 2mm NanoFree™ CSP-16 package, supporting 2.5V–5.5V input and programmable 0.77V–1.4V output (10mV steps) via I²C interface. It delivers up to 3A peak current at 2.5MHz switching frequency with DCS-Control™ architecture, differential remote sensing, and integrated power-save mode - optimized for smartphone processor core supply with dynamic voltage scaling.

For engineers reviewing the TPS62360YZHR datasheet, TPS62360YZHR pinout, TPS62360YZHR application, or TPS62360YZHR equivalent, key selection criteria include I²C-compatible voltage programming, ±0.5% output accuracy over temperature, 120ns minimum on-time, thermal shutdown at 150°C, and support for fast load transient response in submicron SoC power domains.

Technical Context

The TPS62360YZHR implements a high-frequency synchronous buck topology with integrated P-MOS high-side and N-MOS low-side switches (R_DS(on) = 25–75 mΩ / 25–50 mΩ), DCS-Control™ adaptive loop compensation, and dual-mode operation (auto PFM/PWM or forced PWM). Its differential remote sense inputs (SENSE+, SENSE−) enable precise regulation at the load under varying PCB IR drop.

Control logic includes I²C high-speed mode (3.4 MHz), programmable slew rate via RMP[2:0] bits (0.25–32 mV/µs), dedicated hardware VSEL0/VSEL1 pins for preset voltage transitions, and robust protection: overtemperature shutdown (150°C, 20°C hysteresis), input UVLO (2.3V/1.3V thresholds), and soft-start.

Key Specifications

Pinout & Package

TPS62360YZHR uses a 16-bump, 2mm × 2mm NanoFree™ CSP (YZH package) with bottom-side solder bumps. Thermal performance is characterized by θ_JA = 94.8°C/W (JEDEC high-K board) and ψ_JB = 57°C/W for junction-to-board estimation.

FAQ

What is the maximum continuous output current supported by the TPS62360YZHR?

The TPS62360YZHR 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 - confirmed in TI's thermal lifetime guidelines and reflected in the 2.5A rating in the Recommended Operating Conditions table.

Does the TPS62360YZHR support true remote sensing, and how is it implemented?

Yes, the TPS62360YZHR implements true differential remote sensing using dedicated SENSE+ and SENSE− pins. These inputs measure voltage directly at the load, enabling the regulator to compensate for IR drop across PCB traces. The internal sense resistor is 2.2MΩ, and layout requires connecting SENSE+ to the load's power node and SENSE− to the load's ground node - both as close as possible to the SoC power pins.

What I²C modes does the TPS62360YZHR support, and what are the timing limits?

The TPS62360YZHR supports Standard Mode (100 kHz), Fast Mode (400 kHz), and High-Speed Mode (3.4 MHz for write/read with ≤100 pF bus capacitance). Key timing parameters include t_LOW/t_HIGH down to 160 ns/60 ns in high-speed mode, and data hold time (t_HD,DATA) of 0–70 ns - all specified in the I²C Interface Timing Requirements table of the SLVSAU9C datasheet.

How does the TPS62360YZHR handle thermal protection, and what are the trip thresholds?

The TPS62360YZHR features two thermal safeguards: die temperature early warning at 120°C (flagged internally but not latched), and thermal shutdown at 150°C with 20°C hysteresis. Upon reaching 150°C, the device disables switching and holds output in high-impedance state until junction temperature falls below 130°C, then resumes normal operation - verified in the Absolute Maximum Ratings and Electrical Characteristics sections.

Can the TPS62360YZHR be used without I²C communication, relying only on VSEL pins?

Yes, the TPS62360YZHR can operate without I²C by using the VSEL0 and VSEL1 pins to select among four factory-programmed output voltages (1.40V, 1.00V, 1.40V, 1.10V). These pins accept logic HIGH/LOW inputs with internal 300kΩ pulldowns, enabling simple hardware-based voltage state selection - fully documented in the Ordering Information and Pin Functions tables.
