Product details
Overview
TPS62350YZGR from Texas Instruments is a 3-MHz synchronous step-down DC-DC converter in NanoFree™ CSP-12 packaging, delivering up to 800 mA output current with I²C-compatible voltage programming (0.75 V–1.5375 V), ±2% PWM DC accuracy, and 88% efficiency at full switching frequency. It serves as core power supply for low-voltage DSPs and application processors in smartphones.
For engineers reviewing the TPS62350YZGR datasheet, TPS62350YZGR pinout, TPS62350YZGR application, or TPS62350YZGR equivalent, key selection factors include its 35-ns minimum on-time, 28-µA quiescent current in Light PFM mode, I²C interface supporting up to 3.4 Mbps, and dual power-save modes optimized for load transients and efficiency.
Technical Context
The TPS62350YZGR integrates a 3-MHz fixed-frequency PWM controller with adaptive Light PFM and Fast PFM power-save modes, enabling seamless transition between high-efficiency light-load operation and transient-responsive active regulation. Its internal 6-bit DAC sets output voltage via I²C commands with 12.5-mV resolution.
It features dual MOSFET power switches (P-channel rDS(on) = 250 mΩ typ, N-channel rDS(on) = 150 mΩ typ at 3.6 V), programmable enable/discharge logic, and synchronization capability to external clock signals. Thermal shutdown activates at 150°C with 20°C hysteresis.

Pinout & Package
NanoFree™ CSP-12 package (1.6 mm × 1.6 mm, 0.5-mm pitch) with bottom-side solder bumps; thermally enhanced via internal PGND connection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PVIN | Power input for high-side switch | Connects directly to input bulk capacitor; separate from AVIN to isolate analog and power paths |
| AVIN | Analog input supply | Bias source for control circuitry; must be decoupled locally to minimize noise coupling |

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 |

FAQ
What is the default output voltage of the TPS62350YZGR?
The TPS62350YZGR has a factory-default output voltage of 1.05 V, programmable via I²C interface across a range of 0.75 V to 1.5375 V in 12.5-mV increments. This default setting is confirmed in the Ordering Information table of the SLVS540E datasheet and applies when all I²C registers retain their power-on reset values.
Does the TPS62350YZGR support external clock synchronization?
Yes, the TPS62350YZGR supports external clock synchronization via the SYNC pin, accepting input frequencies from 2.65 MHz to 3.35 MHz. When driven by an external clock, the device aligns its internal 3-MHz oscillator to that signal-reducing EMI by eliminating beat frequencies and enabling deterministic timing in multi-rail systems.
What package type is used for the TPS62350YZGR?
The TPS62350YZGR uses the NanoFree™ CSP-12 package (1.6 mm × 1.6 mm, 0.5-mm pitch), a chip-scale package with bottom-side solder bumps. This is explicitly stated in the Ordering Information table and Pin Assignments section of the SLVS540E datasheet, distinguishing it from the QFN-10 option used by other variants like TPS62350DRC.
How does the TPS62350YZGR manage efficiency at light loads?
The TPS62350YZGR employs two distinct power-save modes: Light PFM (28 µA quiescent current) for maximum battery life during idle, and Fast PFM for improved transient response. Mode selection is controlled via I²C register bits or hardware VSEL pin, allowing system firmware to dynamically optimize between efficiency and responsiveness based on real-time load demand.
What is the minimum on-time specification for the TPS62350YZGR?
The TPS62350YZGR has a guaranteed minimum on-time of 35 ns, enabling high step-down ratios (e.g., 3.6 V input to 0.75 V output) while maintaining 3-MHz fixed-frequency operation. This parameter is specified in the Electrical Characteristics table and is critical for stable regulation at low output voltages without requiring frequency foldback or pulse-skipping artifacts.
