Product details
Overview
TPS626765YFDR from Texas Instruments is a 6-MHz synchronous step-down DC-DC converter in NanoFree™ DSBGA-6 packaging, delivering 1.05 V at up to 650 mA for Li-ion–powered portable electronics. It features 17 μA quiescent current in PFM mode, ±2% total DC output voltage accuracy, and spread-spectrum PWM operation for low-noise power delivery in space-constrained applications such as smartphone camera modules.
For engineers reviewing the TPS626765YFDR datasheet, TPS626765YFDR pinout, TPS626765YFDR application, or TPS626765YFDR equivalent, key selection criteria include its 2.3 V–4.8 V input range, 6-MHz fixed-frequency operation with automatic PFM/PWM transition, ultra-thin 0.4 mm max height CSP package, and integrated power-save mode for battery life extension in always-on subsystems.
Technical Context
The TPS626765YFDR employs a frequency-locked ring-oscillating modulator architecture-eliminating traditional compensation networks-to achieve instantaneous load/line transient response without external loop components. Its dual-mode control (PFM at light loads, regulated 6-MHz PWM at higher loads) enables high efficiency across 0–650 mA while maintaining low output ripple and tight DC regulation.
It integrates P-channel and N-channel MOSFETs with on-resistances of 170 mΩ and 120 mΩ (at VGS = 3.6 V), supports external clock detection (4–27 MHz), and includes an internal 70–150 Ω discharge resistor for controlled power-down sequencing-critical for rail-ordering compliance in multi-rail mobile SoC systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.05 V with ±2% total DC accuracy over line/load/temperature-ensures stable core supply for low-voltage digital ICs. |
| Max Output Current | 650 mA continuous-supports high-efficiency conversion for camera ISP, RF transceivers, or application processors' I/O rails. |
| Switching Frequency | 6 MHz nominal (5.4–6.6 MHz range)-enables use of sub-1 µH chip inductors and <10 mm² total solution size. |
| Quiescent Current | 17 µA typical in PFM mode-extends battery runtime in standby or sensor-monitoring states. |
| Input Voltage Range | 2.3 V to 4.8 V-fully covers Li-ion battery discharge curve (3.0–4.2 V nominal + extended range). |
| Package | DSBGA-6 (1.22 mm × 0.85 mm, 0.4 mm max height)-meets ultra-thin profile requirements for slim mobile devices. |
| PSRR | ≥35 dB from 1 kHz to 10 kHz-suppresses noise coupling from noisy system rails into sensitive analog/digital loads. |
Pinout & Package
TPS626765YFDR uses a 6-pin NanoFree™ DSBGA (DSBGA-6) package with 0.4 mm maximum height and 0.5 mm ball pitch. The die-side-up CSP construction places all terminals on the bottom surface in a 2×3 array.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| FB (C1) | Feedback sense input | Connects directly to VOUT to close regulation loop; internal 480 kΩ divider sets 1.05 V output-no external resistors required. |
| VIN (A2) | Power input | Accepts 2.3–4.8 V; requires local 2.2 µF ceramic capacitor for high-frequency decoupling near the ball. |
| SW (B1) | Switch node | Drain connection of internal P/N-MOSFET pair; connects to inductor and must be routed with minimal loop area to reduce EMI. |
| EN (B2) | Enable control | Active-high logic input; pulled high to enable, grounded to shut down (0.2–1 µA shutdown current); supports external clock wake-up. |
| MODE (A1) | Operation mode select | Low = auto PFM/PWM; High = forced PWM only-used to eliminate PFM noise in noise-sensitive analog sections. |
| GND (C2) | Power ground | Primary return path for switch current and feedback reference; must be connected to solid PCB ground plane under the package. |
Key Features
| Feature | Design Value |
|---|---|
| 92% peak efficiency at 6 MHz | Enables high-power-density conversion with minimal thermal rise in sealed handheld enclosures. |
| Spread-spectrum PWM modulation | Reduces peak EMI by dithering switching frequency-simplifies FCC/CE radiated emissions compliance. |
| Low-ripple PFM mode | Maintains <16 mVPP output ripple at 1 mA load-preserves signal integrity for precision analog sensors. |
| Three external components | Only one 0603 inductor + two 0402 capacitors required-reduces BOM count, board area, and assembly cost. |
| Sub-0.33-mm component profile | Supports mechanical stack-up constraints in <7 mm thick smartphones and wearables. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS626751YFD | Same 1.2 V output, identical package and pinout, but adds output discharge function activated during shutdown. | Suitable where rapid VOUT discharge is required for rail sequencing or safety-critical reset behavior. | Select TPS626751YFD if system-level design mandates controlled discharge of the 1.2 V rail; otherwise TPS626765YFDR provides optimal efficiency at 1.05 V. |
| TPS62672YFD | 1.5 V fixed output, same 6-MHz operation and 650 mA capability, but lacks output discharge feature. | Used in higher-voltage I/O domains (e.g., USB PHY, MIPI D-PHY) where 1.5 V compliance is required. | Choose TPS62672YFD when interfacing with 1.5 V–compliant peripherals; TPS626765YFDR remains preferred for 1.05 V core logic rails. |
Compared with TPS626751YFD and TPS62672YFD, the TPS626765YFDR uniquely delivers 1.05 V output with 650 mA capability in the same ultra-thin CSP package-making it the only direct fit for next-generation low-voltage mobile SoC I/O domains requiring precise 1.05 V regulation and minimal board footprint.

FAQ
What is the output voltage of the TPS626765YFDR?
The TPS626765YFDR provides a fixed 1.05 V output voltage with ±2% total DC accuracy across input voltage (2.3 V–4.8 V), load current (0–650 mA), and temperature (–40°C to +85°C). This value is factory-trimmed and requires no external feedback resistors-FB pin connects directly to VOUT.
Does the TPS626765YFDR support forced PWM mode?
Yes, the TPS626765YFDR supports forced PWM mode via the MODE pin: applying a logic HIGH to MODE disables PFM operation and locks the device into regulated 6-MHz PWM mode regardless of load current. This eliminates frequency variation in noise-sensitive analog sections while maintaining high efficiency above ~10 mA.
What is the recommended inductor value for the TPS626765YFDR?
The TPS626765YFDR is optimized for 0.3 µH to 1.8 µH inductors, with typical designs using 0.47 µH or 1.0 µH 0603-size chip inductors (e.g., Murata LQM21PN1R0NGR). Lower inductance enables smaller size and faster transient response; higher inductance improves light-load efficiency but increases solution footprint.
How does the TPS626765YFDR achieve low EMI in mobile designs?
The TPS626765YFDR reduces EMI through spread-spectrum PWM modulation (dithering the 6-MHz switching frequency), a non-linear control architecture with instantaneous transient response, and ultra-low output ripple (<16 mVPP) in PFM mode-minimizing both conducted and radiated noise that could interfere with cellular, GPS, or Bluetooth™ receivers.
Is the TPS626765YFDR pin-compatible with other TPS6267x variants?
Yes, all TPS6267x devices-including TPS626765YFDR-share identical DSBGA-6 (1.22 mm × 0.85 mm) packaging and pinout (VIN, SW, FB, MODE, EN, GND). This allows drop-in replacement across output voltages (1.05 V to 2.1 V) and feature sets (e.g., output discharge) without PCB layout changes.
