Product details
Overview
TPS62672YFDR from Texas Instruments is a 6-MHz synchronous step-down DC-DC converter in a 6-pin NanoFree™ CSP package (1.22 mm × 0.85 mm, height < 0.4 mm), delivering up to 650 mA at fixed 1.5 V output. It operates from 2.3 V to 4.8 V input, achieves 92% peak efficiency, and features 17 µA quiescent current in PFM mode-optimized for Li-ion–powered mobile applications including CMOS camera modules and Bluetooth/WLAN subsystems.
For engineers reviewing the TPS62672YFDR datasheet, TPS62672YFDR pinout, TPS62672YFDR application, or TPS62672YFDR equivalent, key selection criteria include its ultra-thin 0.4-mm profile, spread-spectrum PWM noise reduction, ±2% DC output accuracy, and support for external clock presence detection enabling system-level power sequencing.
Technical Context
The TPS62672YFDR uses a frequency-locked ring-oscillating modulator architecture-eliminating traditional voltage-mode or current-mode compensation loops-to deliver instantaneous load/line transient response. It dynamically switches between regulated 6-MHz PWM (at ≥100 mA) and low-quiescent-current PFM (at light loads), with MODE pin control enabling forced-PWM operation for noise-sensitive circuits.
Its integrated dual MOSFET power stage features 170 mΩ P-channel and 120 mΩ N-channel RDS(on) at 3.6 V, supporting high-efficiency operation across the full 2.3–4.8 V input range. The device includes undervoltage lockout (2.1 V threshold), thermal shutdown (140 °C), and 35 dB PSRR from 1 kHz to 10 kHz-enabling direct LDO replacement in RF and analog signal chains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.5 V with ±2% total DC accuracy over line/load/temperature-ensures stable core supply for low-voltage processors and sensors. |
| Max Output Current | 650 mA continuous-supports demanding digital subsystems like camera ISPs and baseband ICs without external current boosting. |
| 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. |
| IQ (PFM Mode) | 17 µA typical-extends battery runtime in standby/sleep states of portable devices. |
| Input Voltage Range | 2.3 V to 4.8 V-fully covers single-cell Li-ion battery discharge curve (3.0–4.2 V nominal, down to 2.5 V cutoff). |
| PSRR (1–10 kHz) | ≥35 dB-suppresses switching noise coupling into sensitive analog rails (e.g., ADC references, RF synthesizers). |
| Package | 6-pin DSBGA (NanoFree™), 1.22 mm × 0.85 mm, 0.4 mm max height-meets strict Z-height constraints in slim smartphones and wearables. |
Pinout & Package
TPS62672YFDR is housed in a 6-pin DSBGA (NanoFree™) package with 0.4 mm maximum height and 0.5 mm pitch. Pin assignment is defined per TI SLVS952G datasheet Figure 7 (top/bottom view).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| FB (C1) | Feedback sense input | Connects directly to VOUT to regulate output; internal 480 kΩ divider sets 1.5 V-no external resistors required. |
| VIN (A2) | Power input | Accepts 2.3–4.8 V; requires local 2.2 µF ceramic capacitor (0402) for high-frequency decoupling. |
| SW (B1) | Switch node | Drives external 0.47 µH inductor; connects to drain of internal P/N-MOSFET pair-requires tight layout to minimize EMI. |
| EN (B2) | Enable control | Active-high logic input; pulls to GND for shutdown (ISD = 0.2–1 µA); supports external clock detect for auto-wake. |
| MODE (A1) | Operating mode select | LOW = auto PFM/PWM transition; HIGH = forced PWM-critical for noise-sensitive RF sections. |
| GND (C2) | Power ground | Primary return path; must be connected to solid PCB ground plane beneath CSP die for thermal and EMI performance. |
Key Features
| Feature | Design Value |
|---|---|
| Spread-spectrum PWM modulation | Reduces peak EMI by dithering 6-MHz switching frequency-enables compliance with CISPR-22 Class B radiated emissions limits without shielding. |
| Ultra-low 0.4-mm profile | Enables integration under displays or in stacked PCB assemblies where Z-height is constrained to <0.5 mm. |
| Three external components | Only one 0603 inductor + two 0402 capacitors required-minimizes BOM count and board area vs. competing buck converters. |
| External clock presence detection | Automatically powers up when 4–27 MHz clock is detected on EN pin-simplifies power sequencing in multi-rail SoC systems. |
| Best-in-class transient response | No compensation network needed; recovers from 100-mA load step in <2 µs-prevents brownout during burst-mode processor activity. |
Applications
| CMOS Camera Module Power | Smartphone Baseband Core Supply |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62671YFDR | Fixed 1.8-V output; identical package, pinout, and feature set except output voltage. | Targets 1.8-V I/O or memory rails instead of 1.5-V core supplies. | Select when system requires 1.8 V with same size, efficiency, and noise performance. |
| TPS62674YFDR | Fixed 1.26-V output; adds output discharge function and PWM-only operation (no PFM mode). | Suited for always-on low-power logic rails where output discharge prevents floating states during shutdown. | Choose for 1.26-V FPGA/configurable logic rails needing controlled discharge and deterministic PWM timing. |
Compared with TPS62671YFDR and TPS62674YFDR, the TPS62672YFDR uniquely balances 1.5-V core voltage requirements with adaptive PFM/PWM efficiency optimization and spread-spectrum noise control-making it optimal for mixed-signal mobile SoC subsystems.

FAQ
What is the recommended inductor value for TPS62672YFDR?
The TPS62672YFDR is optimized for 0.47 µH inductors (e.g., Murata LQM21PN0R47NGR). The datasheet specifies 0.3–1.8 µH range, but 0.47 µH delivers optimal balance of size, efficiency (>90% at 100 mA), and transient response. Using values outside this range may degrade PFM-mode ripple or increase peak-to-peak output voltage deviation beyond 16 mVpp.
Does TPS62672YFDR support external synchronization?
No, the TPS62672YFDR does not support external clock synchronization. It features clock presence detection on the EN pin (4–27 MHz) to auto-wake from shutdown, but its internal 6-MHz oscillator is not synchronizable. For synchronized switching, consider TI's TPS62864 or TPS62933 families.
What is the thermal resistance (RθJA) of TPS62672YFDR in its YFD package?
The TPS62672YFDR in the 6-pin DSBGA (YFD) package has a junction-to-ambient thermal resistance (RθJA) of 125 °C/W, measured per JEDEC JESD51-7 standard on a 1-in² 2-layer board with 2-oz copper. This value assumes proper thermal vias under the exposed die pad and adequate PCB copper area for heat spreading.
Can TPS62672YFDR operate with only ceramic capacitors?
Yes, the TPS62672YFDR is designed for all-ceramic operation: 2.2 µF input (0402) and 4.7 µF output (0402) capacitors are specified in the datasheet. Its control architecture eliminates need for electrolytic or tantalum bulk capacitance-reducing board area and improving reliability in high-vibration environments.
What is the minimum load current required for TPS62672YFDR to maintain regulation?
The TPS62672YFDR maintains regulation down to 0 mA load current in both PFM and PWM modes. Its feedback loop remains stable with no minimum load requirement, enabling use in always-on sensor nodes or standby power domains where output current drops to microamps between wake events.
