Product details
Overview
TPS62675YFDR from Texas Instruments is a 6-MHz synchronous step-down DC-DC converter in NanoFree™ DSBGA-6 packaging (1.22 mm × 0.85 mm, height < 0.4 mm), delivering 1.2 V fixed output at up to 650 mA load current with ±2% total DC voltage accuracy, 17 μA quiescent current in PFM mode, and 92% peak efficiency - optimized for Li-ion-powered mobile applications including CMOS camera modules and Bluetooth/WLAN subsystems.
For engineers reviewing the TPS62675YFDR datasheet, TPS62675YFDR pinout, TPS62675YFDR application, or TPS62675YFDR equivalent, key selection criteria include its 2.3 V–4.8 V input range, spread-spectrum PWM operation for EMI reduction, PFM/PWM auto-mode transition, 6-MHz regulated switching frequency, and ultra-low profile CSP package enabling sub-10 mm² power solutions.
Technical Context
The TPS62675YFDR employs a frequency-locked ring-oscillating modulator architecture-eliminating traditional compensated feedback loops-to achieve instantaneous transient response and enable use of miniature 0603 inductors and 0402 ceramic capacitors. Its dual-mode operation (PFM at light loads, PWM at heavy loads) is controlled by the MODE pin and internally managed via load-current detection.
It integrates P-channel and N-channel MOSFETs with on-resistances of 170 mΩ/120 mΩ (at VGS = 3.6 V), supports external clock presence detection (4–27 MHz), and features spread-spectrum dithering to reduce conducted and radiated noise-critical for noise-sensitive RF and imaging subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.2 V with ±2% total DC accuracy across 0–650 mA load and 2.3–4.8 V input - ensures stable core supply for low-voltage processors and sensors. |
| Switching Frequency | Regulated 6 MHz (5.4–6.6 MHz) in PWM mode - enables use of sub-1 µH chip inductors and minimizes output ripple without large LC filters. |
| Quiescent Current | 17 µA typical in PFM mode - extends battery life in standby and low-activity states of portable devices. |
| Input Voltage Range | 2.3 V to 4.8 V - fully supports single-cell Li-ion batteries across full discharge curve (including extended-range operation). |
| Peak Efficiency | 92% at 6 MHz - achieves higher conversion efficiency than LDOs while maintaining low-noise performance via spread-spectrum PWM. |
| PSRR | ≥35 dB from 1 kHz to 10 kHz - suppresses input supply noise critical for analog/RF circuitry powered from shared rails. |
| Package | DSBGA-6 (NanoFree™), 1.22 mm × 0.85 mm, max height 0.4 mm - enables ultra-thin, space-constrained PCB layouts in smartphones and wearables. |
Pinout & Package
TPS62675YFDR uses a 6-pin NanoFree™ DSBGA (CSP) package with 0.4 mm maximum height and 0.5 mm ball pitch. The die-side-up top view places pins in a 2×3 array; bottom-view ball mapping matches standard CSP layout conventions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| FB (C1) | Feedback sense input | Connects directly to VOUT; sets regulation point via internal 1.2 V reference - no external resistor divider required for fixed-output variants. |
| VIN (A2) | Power input | Accepts 2.3–4.8 V; supplies bias and switching circuitry - requires local 2.2 µF ceramic decoupling per TI layout guidelines. |
| SW (B1) | Switch node | Drain connection of internal P/N-MOSFET pair; connects to inductor - high dv/dt node requiring tight loop area and ground shielding. |
| EN (B2) | Enable control | Active-high logic input; pull to GND for shutdown (ISD = 0.2–1 µA); supports external clock detect wake-up (4–27 MHz). |
| MODE (A1) | Operating mode select | LOW = auto PFM/PWM transition; HIGH = forced PWM (low-noise mode) - must be terminated, not floating. |
| GND (C2) | Power ground | Primary return path for power and control circuits - requires low-impedance connection to thermal pad and system ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Spread-spectrum PWM modulation | Reduces peak EMI by dithering 6-MHz switching frequency - eliminates need for external EMI filters in compact RF modules. |
| PFM mode with 17 µA IQ | Extends battery runtime during display-off or sensor-idle states without compromising wake-up latency. |
| 6-MHz regulated frequency operation | Enables use of 0.47 µH chip inductors (e.g., Murata LQM21PN0R47NGR) and 2.2–4.7 µF 0402 ceramics - shrinks solution size to <10 mm². |
| ±2% total DC output accuracy | Meets tight tolerance requirements for 1.2 V FPGA cores, DSPs, and low-power microcontrollers without post-regulation. |
| Ultra-thin NanoFree™ DSBGA-6 | 0.4 mm max height allows integration beneath displays or in stacked-die modules where Z-height is constrained. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS626751YFDR | Same 1.2 V output and 650 mA rating, but adds output discharge function during shutdown. | Required where rapid VOUT ramp-down is needed to meet system-level power sequencing or leakage specs. | Select TPS626751YFDR only if output discharge is mandated; otherwise TPS62675YFDR offers identical efficiency and footprint. |
| TPS62672YFDR | 1.5 V fixed output, same 650 mA capability, identical package and feature set (SSM, PFM/PWM, 6 MHz). | Used when system architecture requires 1.5 V rail for specific I/O or interface logic instead of 1.2 V core. | Choose TPS62672YFDR for 1.5 V applications; pinout and layout are identical - only BOM and routing differ. |
Compared with TPS626751YFDR, the TPS62675YFDR lacks output discharge but offers identical efficiency, quiescent current, and transient performance; compared with TPS62672YFDR, it delivers 1.2 V instead of 1.5 V - both alternatives share the same DSBGA-6 footprint and support identical external components.

FAQ
What is the maximum continuous output current supported by the TPS62675YFDR?
The TPS62675YFDR supports up to 650 mA of continuous output current across its full input voltage range (2.3 V–4.8 V) and ambient temperature range (–40°C to +85°C), as specified in the Recommended Operating Conditions table of the SLVS952G datasheet. This rating applies under PWM and PFM/PWM auto-mode operation with proper thermal layout.
Does the TPS62675YFDR require external feedback resistors to set its output voltage?
No, the TPS62675YFDR does not require external feedback resistors. It is a fixed-output device with an internally trimmed 1.2 V regulation point; the FB pin is connected directly to VOUT to close the control loop. External resistors are only needed for adjustable-output variants like the TPS62674.
How does the MODE pin affect the operation of the TPS62675YFDR?
The MODE pin on the TPS62675YFDR selects between two operating modes: when pulled LOW, the device automatically transitions between PFM (light load) and PWM (heavy load); when pulled HIGH, it forces continuous PWM operation for lower noise and predictable frequency - essential for RF-sensitive applications.
What is the purpose of spread-spectrum modulation in the TPS62675YFDR?
Spread-spectrum modulation in the TPS62675YFDR dithers the 6-MHz switching frequency to reduce peak energy at harmonic frequencies. This lowers conducted and radiated EMI, easing EMC compliance in compact handheld devices without requiring additional filtering components or shielding.
Can the TPS62675YFDR be synchronized to an external clock signal?
Yes, the TPS62675YFDR supports external clock presence detection on the EN pin within 4–27 MHz. When an external clock is detected, the device wakes from shutdown and synchronizes its internal oscillator - useful for system-level timing coordination and EMI alignment across multiple converters.
