Product details
Overview
TPS62672YFDT from Texas Instruments is a 1.5-V fixed-output, 650-mA synchronous step-down DC-DC converter in a 6-pin NanoFree™ DSBGA package (1.22 mm × 0.85 mm, height < 0.4 mm). It operates at a regulated 6-MHz switching frequency, delivers ±2% total DC output voltage accuracy over 0–650 mA load, achieves 92% peak efficiency, and draws only 17 µA quiescent current in PFM mode - optimized for Li-ion-powered mobile applications including smartphone core logic rails.
For engineers reviewing the TPS62672YFDT datasheet, TPS62672YFDT pinout, TPS62672YFDT application, or TPS62672YFDT equivalent, key selection criteria include its ultra-thin CSP footprint, spread-spectrum PWM noise reduction, 2.3–4.8 V input range compatibility with single-cell batteries, and seamless PFM/PWM auto-transition across load conditions.
Technical Context
The TPS62672YFDT employs a frequency-locked ring-oscillating modulator architecture-eliminating traditional compensation networks-to deliver instantaneous transient response and stable operation with minimal external components (one 0603 inductor, two 0402 capacitors). Its dual-mode control enables automatic transition between high-efficiency PFM (light load) and low-noise, constant-frequency PWM (moderate-to-heavy load).
It integrates both 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 dedicated MODE pin logic to force PWM-only operation for noise-sensitive systems. Thermal shutdown activates at 140°C with 10°C hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.5 V ±2% DC accuracy across 0–650 mA load and 2.3–4.8 V input - ensures stable core supply for ARM Cortex-A/M series processors. |
| Switching Frequency | 6 MHz (±10%) regulated center frequency - enables use of sub-1-µH chip inductors and reduces solution size below 10 mm². |
| Quiescent Current | 17 µA typical in PFM mode - extends battery runtime in standby/sleep states of portable devices. |
| Input Voltage Range | 2.3 V to 4.8 V - fully supports discharge curve of single Li-ion/Li-polymer cells without intermediate regulation. |
| Peak Efficiency | 92% at 6 MHz - achieved at mid-load (e.g., 100–300 mA), reducing thermal stress and PCB heat dissipation. |
| PSRR | ≥35 dB from 1 kHz to 10 kHz - suppresses ripple from noisy shared battery rails, critical for RF and camera subsystems. |
| Load Current Capability | 650 mA continuous output - sufficient for application processors, DDR I/O, or multi-core SoC domains. |
Pinout & Package
TPS62672YFDT uses a 6-pin NanoFree™ DSBGA (YFD) package: 1.22 mm × 0.85 mm body, 0.4 mm max height, solder-ball pitch 0.4 mm. Bottom-side ball layout matches standard CSP-6 footprint with no exposed pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| FB (C1) | Feedback sense input | Connects directly to VOUT node; sets regulation point via internal 1.5-V reference - no external resistor divider required. |
| VIN (A2) | Power input | Accepts 2.3–4.8 V; requires local 2.2-µF ceramic decoupling (0402) placed adjacent to pin for EMI suppression. |
| SW (B1) | Switch node | Drain connection of internal P/N-MOSFET pair; routes to inductor; must be routed with minimal loop area to reduce radiated emissions. |
| EN (B2) | Enable control | Active-high logic input; pull to GND for shutdown (ISD ≤ 1 µA); supports external clock wake-up detection (4–27 MHz). |
| MODE (A1) | Operation mode select | LOW = auto PFM/PWM transition; HIGH = forced PWM-only mode - used to eliminate PFM frequency variation in audio/RF sections. |
| GND (C2) | Ground reference | Primary return path for power and signal; must connect to solid ground plane under CSP body for thermal and EMI performance. |
Key Features
| Feature | Design Value |
|---|---|
| Spread-spectrum PWM modulation | Reduces peak EMI by dithering switching frequency - eliminates need for external EMI filters in space-constrained mobile designs. |
| Ultra-low profile packaging | DSBGA-6 with 0.4 mm max height enables integration beneath displays or stacked PCBs in slim smartphones and wearables. |
| Three-component solution | Requires only one 0603 inductor and two 0402 MLCCs - minimizes BOM count, assembly cost, and board area vs. conventional buck regulators. |
| Best-in-class transient response | No traditional feedback loop; ring-oscillator architecture provides near-instantaneous load/line step recovery - critical for burst-mode processor loads. |
| Output discharge function | Not supported on TPS62672YFDT (only on TPS62674/TPS626751/TPS626765/TPS62679) - output remains floating during shutdown. |

FAQ
What is the maximum continuous output current of the TPS62672YFDT?
The TPS62672YFDT supports up to 650 mA of 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), as confirmed in the Recommended Operating Conditions table of the SLVS952G datasheet. This rating applies under proper PCB layout with adequate thermal relief and recommended 0603 inductor (e.g., Murata LQM21PN1R0NGR).
Does the TPS62672YFDT support output voltage discharge during shutdown?
No, the TPS62672YFDT does not integrate an output discharge function. That feature is explicitly reserved for TPS62674YFD, TPS626751YFD, TPS626765YFD, and TPS62679ZYFM per the Device Comparison Table in SLVS952G. When EN is pulled low, the TPS62672YFDT disables switching and leaves VOUT floating - external circuitry is required for active discharge.
What is the purpose of the MODE pin on the TPS62672YFDT?
The MODE pin on the TPS62672YFDT selects between two operational modes: pulled LOW for automatic PFM/PWM transition (optimal efficiency across load range), or pulled HIGH for forced PWM-only operation (constant 6-MHz frequency, lower noise, preferred for RF/audio sections). The pin must never be left floating and requires a defined logic level per Pin Functions table.
Can the TPS62672YFDT be synchronized to an external clock?
Yes - the TPS62672YFDT supports external clock presence detection on the EN pin within 4 MHz to 27 MHz. When an external clock is detected, the device automatically powers up and synchronizes its internal oscillator to that frequency, enabling deterministic EMI management in multi-rail systems. This is documented in the Electrical Characteristics section under EXTCLK parameters.
What package type and dimensions does the TPS62672YFDT use?
The TPS62672YFDT uses a 6-pin NanoFree™ DSBGA (YFD) package: nominal body size 1.22 mm × 0.85 mm, maximum height 0.4 mm, and 0.4 mm ball pitch. This ultra-thin chip-scale package is specified in the Device Information table and Mechanical, Packaging, and Orderable Information section of SLVS952G.
