Product details
Overview
TPS6208818YFPT from Texas Instruments is a 2.4V–5.5V input, 1.8V fixed-output, 3A synchronous step-down DC/DC converter in a 0.8mm × 1.2mm × 0.5mm wafer chip-scale package (YFP/DSBGA-6). It features DCS-Control topology, 4MHz switching frequency, 1% output voltage accuracy, 4µA quiescent current, and integrated 26mΩ/26mΩ power MOSFETs - optimized for ultra-thin embedded power in space-constrained mobile and optical modules.
For engineers reviewing the TPS6208818YFPT datasheet, TPS6208818YFPT pinout, TPS6208818YFPT application, or TPS6208818YFPT equivalent, key selection criteria include its 0.3mm–0.5mm height envelope, embedded-ready WCSP footprint, PFM/PWM auto-mode transition, active output discharge, and power-good signaling - all critical for battery-powered wearable and camera module designs requiring high light-load efficiency and minimal board area.
Technical Context
The TPS6208818YFPT implements TI's DCS-Control architecture to deliver seamless PWM-to-power-save mode transition without output voltage disturbance. Its fixed 1.8V output eliminates external feedback resistors, while the 4MHz switching frequency enables use of sub-0.3µH inductors and 10µF ceramic capacitors - supporting <12mm² total solution size and <0.6mm profile.
It integrates thermal shutdown (150°C trip), hiccup-mode short-circuit protection, undervoltage lockout (2.2V nominal), and 100% duty-cycle low-dropout operation. The open-drain PG pin provides rail sequencing capability with 92–110% output voltage monitoring window and 1mA sink capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.4 V to 5.5 V - supports single-cell Li-ion, Li-polymer, and 3.3 V/5 V system rails without pre-regulation. |
| Output Voltage | Fixed 1.8 V ±1% - eliminates external resistor divider, reduces BOM count, and improves noise immunity. |
| Max Output Current | 3 A continuous - sufficient for core logic, image sensors, and SSD controllers in compact portable systems. |
| Switching Frequency | 4 MHz - enables use of 0.24 µH inductors and small 0402/0603 MLCCs, minimizing solution footprint and height. |
| Quiescent Current | 4 µA - extends battery life in always-on wearable and IoT standby modes without sacrificing wake-up response. |
| Package | YFP (DSBGA-6), 0.8 mm × 1.2 mm × 0.5 mm - wafer-level CSP with 0.4 mm pitch, designed for embedding and ultra-low-profile PCB assembly. |
| Efficiency Peak | Up to 95% - achieved at medium-to-heavy loads using synchronous rectification and low RDS(on) (26 mΩ/26 mΩ) FETs. |
Pinout & Package
TPS6208818YFPT uses a 6-pin DSBGA (YFP) wafer chip-scale package measuring 0.8 mm × 1.2 mm × 0.5 mm with 0.4 mm pitch. The package is optimized for embedded applications and supports <0.6 mm total board height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN | Enable input | Active-high logic control; threshold ~0.89 V (rising); must be pulled high to operate - no floating allowed. |
| VIN | Input voltage supply | Accepts 2.4–5.5 V; connects to input capacitor bank near package edge to minimize loop inductance. |
| PG | Power-good open-drain output | Sinks up to 1 mA; requires external pullup ≤5.5 V; signals valid regulation (92–110% of 1.8 V) for rail sequencing. |
| SW | Power switch node | Connects to inductor; carries high di/dt switching current - demands tight layout and thermal relief to GND plane. |
| FB | Feedback input | Internally tied to 1.8 V output - must be directly connected to VOUT; no external resistors required. |
| GND | Power ground | Primary return path for power stage and control circuitry; requires low-impedance connection to thermal pad and PCB ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| DCS-Control topology | Enables seamless PWM-to-power-save mode transition with no output voltage glitch - critical for RF-sensitive camera and optical modules. |
| Active output discharge | Internally discharges VOUT through SW pin when EN is low - prevents residual voltage hold-up and ensures clean power-down sequencing. |
| 100% duty-cycle operation | Maintains regulation down to VIN ≈ VOUT + IOUT×RDS(on) - maximizes usable battery voltage range in Li-ion powered wearables. |
| Thermal & hiccup protection | Shuts down at 150°C junction temp; re-enables after 20°C hysteresis; enters hiccup mode after 32 overcurrent events - protects against sustained shorts. |
| Ultra-low profile packaging | 0.5 mm max height YFP package supports embedded PCB designs and <0.6 mm total stack-up - essential for slim smartphones and camera modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS6208818YWC | Same electrical specs but 0.3 mm height YWC package (0.8 mm × 1.2 mm × 0.3 mm) - 0.2 mm lower than YFP. | Better suited for embedded or fully encapsulated designs requiring absolute minimum Z-height; same pinout and thermal performance. | Select YWC if board stacking height is ≤0.5 mm; YFP preferred when thermal pad solderability or rework access is prioritized. |
| TPS6208812YFPT | Identical package and architecture but fixed 1.2 V output; shares same 4 µA IQ, 4 MHz fSW, and DCS-Control features. | Used where 1.2 V core supply is needed instead of 1.8 V - e.g., certain FPGA I/O banks or low-voltage microcontrollers. | Choose only when output voltage requirement differs; not a functional substitute for 1.8 V systems due to hard-coded feedback ratio. |
Compared with TPS6208818YFPT, the YWC variant offers identical regulation and efficiency in a lower-profile package ideal for embedded applications, while the 1.2 V version serves distinct voltage domains - neither is pin-compatible drop-in replacement for 1.8 V operation, and selection depends strictly on height budget and output voltage requirement.

FAQ
What is the maximum continuous output current of the TPS6208818YFPT?
The TPS6208818YFPT delivers up to 3 A continuous output current under recommended operating conditions (TJ ≤ 125°C). At full 3 A load with YFP package, lifetime derating applies above 85°C junction temperature per TI's datasheet guidance. For sustained 3 A operation in thermally constrained environments, thermal design must ensure adequate PCB copper area and airflow.
Does the TPS6208818YFPT require external feedback resistors?
No, the TPS6208818YFPT does not require external feedback resistors. It is a fixed 1.8 V output device with internal resistor divider and feedforward capacitor. The FB pin must be directly connected to the output voltage node (VOUT), and R1/R2/C4 components are omitted - simplifying layout and improving noise immunity compared to adjustable versions.
What package type and dimensions does the TPS6208818YFPT use?
The TPS6208818YFPT uses the YFP package: a 6-pin DSBGA (wafer chip-scale) measuring 0.8 mm × 1.2 mm × 0.5 mm nominal, with 0.4 mm ball pitch. This package is optimized for embedding and ultra-low-profile PCB assembly, supporting total solution heights under 0.6 mm when combined with compatible passive components.
How does the power-good (PG) pin function on the TPS6208818YFPT?
The PG pin on the TPS6208818YFPT is an open-drain output that signals valid regulation when FB voltage is between 92% and 110% of nominal 1.8 V (i.e., 1.656 V to 1.98 V). It sinks up to 1 mA and requires an external pullup resistor to ≤5.5 V. PG asserts after soft-start completes and de-asserts within 20 µs deglitch delay upon fault detection - enabling reliable rail sequencing in multi-rail systems.
Can the TPS6208818YFPT operate in 100% duty cycle mode?
Yes, the TPS6208818YFPT supports 100% duty cycle operation to maintain regulation when input voltage approaches output voltage - critical for maximizing battery utilization. In this mode, the high-side FET remains continuously on while the low-side FET is off. Minimum input voltage for regulation is determined by VOUT + IOUT × RDS(on), where RDS(on) = 26 mΩ.
