Product details
Overview
TPS62650TYFFRQ1 from Texas Instruments is an AEC-Q100 Grade 2 automotive-qualified, 6-MHz synchronous step-down DC-DC converter with I²C interface, delivering up to 800 mA output current, ±2% PWM DC voltage accuracy at 1.2 V, and 38 µA quiescent current. It operates from 2.3 V to 5.5 V input and supports dynamic voltage scaling down to 0.75 V for low-voltage processor core supplies in smartphones and automotive infotainment systems.
For engineers reviewing the TPS62650TYFFRQ1 datasheet, TPS62650TYFFRQ1 pinout, TPS62650TYFFRQ1 application, or TPS62650TYFFRQ1 equivalent, key selection criteria include its 9-pin NanoFree™ CSP package, 6-MHz fixed-frequency operation with automatic PFM/PWM mode switching, I²C-compatible interface (up to 3.4 Mbps), and automotive-grade thermal performance (–40°C to +105°C ambient).
Technical Context
The TPS62650TYFFRQ1 employs a frequency-locked ring-oscillating modulator architecture enabling best-in-class load and line transient response while maintaining 6-MHz regulation across temperature and load. Its integrated 6-bit DAC enables 12.5-mV I²C-programmable output steps between 0.75 V and 1.4375 V.
Internal power switches feature 255 mΩ P-channel and 140 mΩ N-channel MOSFETs (at VGS = 3.6 V), supporting high efficiency across light-load PFM and heavy-load PWM modes. The device includes internal soft-start (<150 µs), undervoltage lockout (2.1 V threshold), and thermal shutdown (140°C) with 15°C hysteresis.

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62651TYFFRQ1 | Identical specs except default output voltage set to 1.05 V (vs 1.2 V for TPS62650TYFFRQ1); shares same I²C register map and pinout. | Optimized for lower-voltage SoC cores; requires no hardware change but may need firmware voltage initialization update. | Select when system baseline voltage is 1.05 V and dynamic scaling range must start lower than 1.2 V. |
| TPS62865ARGTR | Higher 2-A output capability, 2.5-V to 5.5-V input, 1.8-MHz switching, no I²C interface; uses 12-pin WSON package. | Targets higher-current applications like DDR memory termination or multi-core SoCs; lacks programmability and automotive qualification. | Choose for non-automotive, higher-current needs where I²C control and AEC-Q100 compliance are not required. |
Compared with TPS62651TYFFRQ1, the TPS62650TYFFRQ1 offers a higher default output (1.2 V) ideal for standard processor cores, while TPS62865ARGTR trades programmability and qualification for higher current and simpler control-making it unsuitable for automotive DVFS but viable for cost-sensitive industrial loads.

FAQ
What is the default output voltage of the TPS62650TYFFRQ1?
The TPS62650TYFFRQ1 has a factory-default output voltage of 1.20 V, set via internal register configuration and confirmed in the ordering information table. This value is programmable downward to 0.75 V or upward to 1.4375 V in 12.5-mV steps using its I²C interface. The device also supports pin-selectable outputs (e.g., 1.05 V) via the VSEL input, but the TPS62650TYFFRQ1 variant is specified for 1.20 V as the nominal setting.
Does the TPS62650TYFFRQ1 support forced PWM mode?
Yes, the TPS62650TYFFRQ1 supports forced PWM mode via I²C register control (CONTROL1[3:2] bits), disabling automatic PFM/PWM transition. In forced PWM, the device maintains 6-MHz switching regardless of load, ensuring constant frequency for EMI filtering and predictable transient behavior-critical in noise-sensitive automotive audio or camera modules powered by the TPS62650TYFFRQ1.
What package type and dimensions does the TPS62650TYFFRQ1 use?
The TPS62650TYFFRQ1 uses Texas Instruments' NanoFree™ Chip-Scale Package (CSP-9, orderable code YFF-9), measuring 1.2 mm × 1.2 mm with 0.4 mm ball pitch and a maximum height of 0.4 mm. It features nine solder balls on the bottom side (including two GND balls), enabling ultra-compact layouts and eliminating bond wires-key for minimizing footprint in smartphone and automotive display module designs using the TPS62650TYFFRQ1.
How does the TPS62650TYFFRQ1 achieve high efficiency at light loads?
The TPS62650TYFFRQ1 achieves high light-load efficiency by automatically entering power-save mode using pulse-frequency modulation (PFM), reducing switching losses while maintaining regulation. At loads below ~10 mA, it lowers effective switching frequency and skips pulses, achieving >80% efficiency at 0.1 mA output. This behavior is inherent to the TPS62650TYFFRQ1's architecture and requires no external configuration-enabling extended battery life in always-on automotive telematics powered by the TPS62650TYFFRQ1.
Is the TPS62650TYFFRQ1 qualified for automotive applications?
Yes, the TPS62650TYFFRQ1 is AEC-Q100 qualified for Automotive Grade 2 (–40°C to +105°C ambient), with H2-level HBM ESD (2 kV) and C3B-level CDM ESD (750 V) certification. It undergoes rigorous stress testing including thermal cycling, HTOL, and AC/DC life testing per AEC-Q100 Rev H. This qualification makes the TPS62650TYFFRQ1 suitable for front-end infotainment, body control, and ADAS domain controllers where reliability under harsh environmental conditions is essential.
