Product details
Overview
TPS62671YFDR 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 1.8 V at up to 500 mA output current with ±2% total DC voltage accuracy. It operates from 2.3 V to 4.8 V input (Li-ion compatible), achieves 92% peak efficiency, and features PFM/PWM auto-mode switching for ultra-low 17 µA quiescent current in light-load operation - optimized for smartphone core rail and camera module power.
For engineers reviewing the TPS62671YFDR datasheet, TPS62671YFDR pinout, TPS62671YFDR application, or TPS62671YFDR equivalent, key selection considerations include its 6-MHz fixed-frequency PWM with spread-spectrum dithering, sub-0.33-mm profile solution, 35 dB VIN PSRR (1–10 kHz), and support for external clock presence detection enabling noise-sensitive RF subsystems.
Technical Context
The TPS62671YFDR employs a frequency-locked ring-oscillating modulator architecture-eliminating traditional error amplifiers and compensation networks-to deliver instantaneous load/line transient response without loop stability concerns. Its non-linear control enables stable operation with only three surface-mount components: one 0603 MLCC inductor and two 0402 ceramic capacitors.
It integrates dual MOSFET power switches (170 mΩ P-ch / 120 mΩ N-ch typical RDS(on) at 3.6 V), programmable MODE pin logic (PFM/PWM auto-switching vs forced PWM), and dedicated EN pin with external clock detect (4–27 MHz) for synchronized power-up in multi-rail systems.
Key Specifications

Pinout & Package
TPS62671YFDR uses a 6-pin NanoFree™ DSBGA package (1.22 mm × 0.85 mm, 0.4 mm max height) with bottom-side solder balls. Pin mapping follows JEDEC MO-248 standard for CSP devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| FB (C1) | Feedback sense input | Connects directly to VOUT node; internal 480 kΩ divider sets 1.8 V regulation point - no external resistors required |
| VIN (A2) | Power input supply | Accepts 2.3–4.8 V; requires local 2.2 µF ceramic capacitor (0402) for high-frequency decoupling |
| SW (B1) | Switch node | Drain connection of internal P/N-MOSFET pair; interfaces with external 0.47 µH inductor (0603) |
| MODE (A1) | Mode selection control | Pull LOW for auto PFM/PWM; pull HIGH for forced PWM - enables deterministic noise profile in RF sections |
| EN (B2) | Enable input | Active-HIGH logic; detects external 4–27 MHz clock for automatic wake-up - eliminates need for separate timing controller |
| GND (C2) | Ground reference | Primary thermal and signal return path; must be connected to solid PCB ground plane under package |
Key Features
| Feature | Design Value |
|---|---|
| Spread-spectrum PWM | Reduces peak EMI by >10 dB across 10–100 MHz band - meets CISPR-22 Class B without shielding |
| Sub-0.33-mm solution height | Enables placement under display flex cables or beneath stacked memory - critical for <7.5 mm smartphone Z-height |
| Total solution size <10 mm² | Uses only three 0402/0603 passives - cuts BOM count vs. discrete buck controllers requiring 8+ components |
| Low ripple PFM mode | 14 mVPP output ripple at 1 mA load - preserves ADC reference stability in always-on sensor subsystems |
| 6-MHz regulated frequency | Allows use of <1 µH chip inductors (e.g., Murata LQM21PN1R0NGR) - reduces solution volume by 40% vs. 1–2 MHz converters |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62672YFDR | Fixed 1.5 V output; identical 6-MHz spread-spectrum PWM, 17 µA IQ, and DSBGA-6 package | Targets lower-voltage SoC I/O rails (e.g., LPDDR4 interface) instead of 1.8 V camera sensors | Select when system requires 1.5 V with identical footprint and efficiency profile |
| TPS62675YFDR | Fixed 1.2 V output; adds output discharge function; same 6-MHz operation and 17 µA IQ | Suitable for CPU core rails needing fast power-down discharge; not recommended for noise-sensitive analog rails | Choose for 1.2 V core domains where controlled VOUT ramp-down is required during sleep transitions |
Compared with TPS62671YFDR, TPS62672YFDR provides identical performance at 1.5 V for lower-power I/O domains, while TPS62675YFDR adds output discharge for 1.2 V core rails - neither offers 1.8 V regulation or matches TPS62671YFDR's optimized PSRR for camera analog circuits.

FAQ
What is the maximum continuous output current capability of the TPS62671YFDR?
The TPS62671YFDR delivers up to 500 mA continuous output current across its full operating temperature range (–40°C to +85°C) and input voltage range (2.3 V to 4.8 V). Its internal power MOSFETs feature 170 mΩ (P-ch) and 120 mΩ (N-ch) typical RDS(on) at 3.6 V, enabling this rating without external heatsinking in standard PCB layouts.
Does the TPS62671YFDR support external synchronization, and how is it implemented?
Yes, the TPS62671YFDR supports external clock presence detection via its EN pin. When an external clock signal between 4 MHz and 27 MHz is applied to EN, the device automatically powers up and synchronizes its 6-MHz internal oscillator to that clock - eliminating beat frequencies in multi-rail systems and reducing EMI in RF-sensitive designs.
How does the MODE pin affect the TPS62671YFDR's operation in noise-critical applications?
The MODE pin configures the TPS62671YFDR's switching behavior: pulled LOW enables automatic PFM/PWM mode switching for highest light-load efficiency, while pulled HIGH forces continuous 6-MHz PWM operation. In noise-critical applications like camera sensor power, forced PWM eliminates PFM frequency variation and enables precise EMI filtering.
What is the typical output voltage accuracy of the TPS62671YFDR over process, voltage, and temperature?
The TPS62671YFDR maintains ±2% total DC output voltage accuracy across all conditions: 2.3 V to 4.8 V input, 0–500 mA load, and –40°C to +85°C ambient temperature. This specification includes initial tolerance, line regulation (0.23%/V), and load regulation (–0.00045%/mA), ensuring stable 1.8 V supply for precision analog circuits.
Can the TPS62671YFDR replace a linear regulator in a battery-powered system, and what are the efficiency gains?
Yes, the TPS62671YFDR is explicitly designed to replace linear regulators in Li-ion powered systems. At 100 mA output, it achieves 92% efficiency versus ~50% for a typical LDO - reducing power loss by >4× and extending battery life significantly. Its 17 µA quiescent current also outperforms most LDOs in standby mode.
