Product details
Overview
TPS62350YZGT from Texas Instruments is a 3-MHz synchronous step-down DC-DC converter with I²C-compatible interface in NanoFree™ CSP-12 packaging, delivering up to 800 mA output current at 2.7 V input, ±2% PWM DC voltage accuracy, and 88% efficiency at full switching frequency. It serves as a core power supply for low-voltage DSP/processor cores in smartphones and handheld computing devices.
For engineers reviewing the TPS62350YZGT datasheet, TPS62350YZGT pinout, TPS62350YZGT application, or TPS62350YZGT equivalent, key selection criteria include its 0.75–1.5375 V I²C-programmable output range, 35 ns minimum on-time, 28 µA typical quiescent current in Light PFM mode, and support for dynamic voltage scaling down to 12.5 mV steps.
Technical Context
The TPS62350YZGT integrates a 6-bit DAC, dual-mode power-save control (Light PFM/Fast PFM), and a 3-MHz fixed-frequency oscillator with PLL-based timing. Its internal P-channel and N-channel MOSFETs feature rDS(on) of 250 mΩ and 150 mΩ respectively at 3.6 V, enabling high-efficiency operation across light-to-heavy loads.
It supports real-time synchronization to external clock signals via SYNC pin, operates with 2.7–5.5 V input, and uses FB-sense topology with 700–1000 kΩ input impedance. The device enters shutdown with <2 µA current when EN is low and resets all registers on EN rising edge.

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62351YZG | Wider output range (0.9–1.6875 V); default 1.10 V / 1.50 V; identical CSP-12 package and pinout | Targets higher-core-voltage DSPs (e.g., C674x) requiring ≥1.1 V nominal output | Select when default output must be ≥1.10 V and 1.50 V floor is acceptable |
| TPS62355DRC | QFN-10 package; no SYNC pin; default 0.9 V output; same I²C interface and 3-MHz operation | Suitable for space-constrained designs where board area outweighs thermal performance needs | Choose for cost-sensitive QFN-based layouts where external sync is unnecessary |
Compared with TPS62350YZGT, TPS62351YZG offers higher default output voltage but identical feature set and package, while TPS62355DRC trades SYNC capability and thermal performance (θJA = 49°C/W vs. 89°C/W) for smaller footprint and lower cost in QFN form.

FAQ
What is the default output voltage of the TPS62350YZGT?
The TPS62350YZGT has a factory-programmed default output voltage of 1.05 V (roof) and 1.35 V (floor) in its I²C-addressable range of 0.75–1.5375 V. These values are set by internal hardware logic and cannot be altered without I²C write commands. The device powers up at the default value unless reconfigured via SDA/SCL after EN assertion.
Does the TPS62350YZGT support external clock synchronization?
Yes, the TPS62350YZGT supports external clock synchronization via the SYNC pin, which accepts input frequencies from 2.65 MHz to 3.35 MHz. When driven, the internal oscillator locks to the external signal, enabling system-level timing alignment across multiple rails - a critical requirement in multi-processor OMAP platforms where TPS62350YZGT is commonly deployed.
What is the minimum on-time specification for the TPS62350YZGT?
The TPS62350YZGT features a guaranteed minimum on-time of 35 ns for the P-channel MOSFET, enabling stable operation at high duty cycles required for low-output-voltage conversion (e.g., 0.75 V from 2.8 V input). This parameter ensures reliable regulation even under worst-case process/voltage/temperature conditions without pulse-skipping artifacts.
How does the TPS62350YZGT manage power-save modes?
The TPS62350YZGT implements two distinct power-save modes: Light PFM (optimized for lowest quiescent current at light loads) and Fast PFM (optimized for transient response). Mode selection is controlled via I²C register bits or the VSEL pin. In Light PFM, IQ drops to 28 µA; in Fast PFM, output voltage deviation remains ≤±15 mV during 100 mA load steps.
Is the TPS62350YZGT pin-compatible with other members of the TPS6235x family?
Yes, the TPS62350YZGT in CSP-12 packaging shares identical pinout and footprint with TPS62351YZG, TPS62352YZG, TPS62353YZG, TPS62354YZG, and TPS62356YZG. All variants use the same A1–D3 ball map, allowing direct substitution in layouts where output voltage range and default settings meet system requirements.
