Product details
Overview
TPS62352YZGT 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 35-ns minimum on-time for mobile processor core supplies.
For engineers reviewing the TPS62352YZGT datasheet, TPS62352YZGT pinout, TPS62352YZGT application, or TPS62352YZGT equivalent, key selection criteria include I²C-programmable output voltage (0.75 V to 1.4375 V), light-load efficiency optimization via Light PFM mode, 28-µA quiescent current, and synchronization capability to external clock signals.
Technical Context
The TPS62352YZGT integrates a 3-MHz fixed-frequency PWM controller with dual-mode power-save operation-Light PFM for ultra-low quiescent current (28 µA) and Fast PFM for improved transient response-enabling dynamic voltage scaling across DSP/processor cores. Its 6-bit DAC provides 12.5-mV voltage steps over the full output range.
Internal P-channel and N-channel MOSFETs feature typical rDS(on) of 250 mΩ and 150 mΩ respectively at 3.6 V, supporting high-efficiency conversion from 2.7 V–5.5 V input to programmable outputs. The device enters shutdown (<2 µA) when EN is low and supports real-time reconfiguration via I²C up to 3.4 Mbps.

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 V–1.6875 V); default 1.10 V/1.50 V; same CSP-12 package and I²C interface | Better suited for higher-core-voltage DSPs (e.g., C64x+); not suitable for sub-0.9 V operation | Select when target SoC requires ≥0.9 V nominal core voltage and higher upper limit |
| TPS62353YZG | Narrower output range (0.75 V–1.5375 V); default 1.00 V/1.20 V; identical electrical specs and pinout | Optimized for 1.0 V–1.2 V core rails common in mid-tier OMAP3 platforms | Choose for cost-sensitive designs where 1.00 V/1.20 V defaults match system requirements |
Compared with TPS62351YZG and TPS62353YZG, the TPS62352YZGT offers the narrowest upper output limit (1.4375 V) and lowest default voltages (1.05 V/1.20 V), making it ideal for low-voltage, high-efficiency mobile processor cores where tighter voltage margins reduce dynamic power consumption.

FAQ
What is the default output voltage of the TPS62352YZGT?
The TPS62352YZGT has two factory-programmed default output voltages: 1.05 V (roof) and 1.20 V (floor). These values are set by internal hardware logic and cannot be altered via I²C. The actual output is determined by register settings at power-up or through subsequent I²C commands.
Does the TPS62352YZGT support synchronization to an external clock?
Yes, the TPS62352YZGT supports on-the-fly synchronization via its SYNC pin, accepting external clock signals from 2.65 MHz to 3.35 MHz. This feature allows EMI reduction in dense PCB layouts without requiring device reset or register reconfiguration.
What is the maximum output current capability of the TPS62352YZGT?
The TPS62352YZGT delivers up to 800 mA continuous output current when operating from a 2.7 V input. At higher input voltages (≥3.2 V), the device supports up to 1000 mA, subject to thermal derating based on PCB layout and ambient conditions.
How does the TPS62352YZGT manage efficiency at light loads?
The TPS62352YZGT uses two power-save modes: Light PFM achieves 28 µA quiescent current and >80% efficiency at 1 mA load, while Fast PFM improves transient response without sacrificing efficiency below 10 mA. Both modes operate automatically based on load demand.
Is the TPS62352YZGT pin-compatible with other devices in the TPS6235x family?
Yes, all TPS6235x devices in the CSP-12 package-including TPS62352YZGT, TPS62351YZG, and TPS62353YZG-share identical pin assignments and mechanical footprint. Functional differences (e.g., output voltage range, default values) are implemented in firmware and internal logic, not pinout.
