Product details
Overview
TPS6208818YFPR from Texas Instruments is a 2.4V–5.5V input, 1.8V fixed-output, 3A synchronous step-down converter in a 0.8mm × 1.2mm × 0.5mm wafer chip-scale package (YFP/DSBGA-6), featuring DCS-Control topology, 4MHz switching frequency, and 1% output voltage accuracy - deployed in camera modules and optical modules where ultra-small footprint and low-profile power delivery are critical.
For engineers reviewing the TPS6208818YFPR datasheet, TPS6208818YFPR pinout, TPS6208818YFPR application, or TPS6208818YFPR equivalent, key selection considerations include its 4MHz operation enabling sub-1mm² solution size, active output discharge, power-good signaling, and compatibility with embedded PCB embedding processes requiring <0.6mm height.
Technical Context
The TPS6208818YFPR implements TI's DCS-Control architecture-combining adaptive constant-on-time PWM for stable 4MHz operation at medium-to-heavy loads and seamless transition into power-save mode at light loads-achieving up to 95% efficiency across 10μA–3A output current range. Its dual 26mΩ internal MOSFETs support continuous conduction mode and 100% duty-cycle low-dropout operation down to VIN ≈ VOUT + IOUT×RDS(on).
It integrates undervoltage lockout (2.2V threshold), thermal shutdown (150°C), hiccup short-circuit protection, and a dedicated open-drain power-good (PG) output with 92–110% voltage window detection. The EN pin enables logic-level control with 0.89V VIH threshold, and soft-start ensures controlled 1.25ms ramp-up without inrush current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.4V to 5.5V - supports single-cell Li-ion, Li-polymer, and 3.3V/5V rails without external LDO pre-regulation. |
| Output Voltage | Fixed 1.8V ±1% - eliminates external feedback resistors, reduces BOM count, and guarantees precision for core logic and interface I/O rails. |
| Max Output Current | 3A continuous - sufficient for high-speed image sensors and optical drivers without derating below 85°C junction temperature. |
| Switching Frequency | 4MHz nominal - enables use of 0.24μH inductors and 10μF ceramic capacitors, achieving total solution area <12mm² and height <0.6mm. |
| Quiescent Current | 4μA in PFM mode - extends battery runtime in always-on wearable and SSD standby states. |
| Efficiency Peak | Up to 95% at 1A/5VIN→1.8VOUT - minimizes thermal load in thermally constrained embedded modules. |
| Package | YFP (DSBGA-6), 0.8mm × 1.2mm × 0.5mm - wafer-level chip-scale package optimized for PCB embedding and automated assembly. |
Pinout & Package
TPS6208818YFPR uses a 6-pin DSBGA (Wafer Chip Scale Package) with 0.4mm pitch and 0.5mm nominal height. The YFP variant features bottom-side solder bumps aligned to a 2×3 grid.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN | Enable input | Active-high logic control; must be pulled ≥0.89V to enable regulation; draws only 0.1μA leakage when floating. |
| VIN | Input supply | Accepts 2.4–5.5V; requires local 4.7μF ceramic capacitor placed adjacent to minimize high-frequency noise coupling. |
| PG | Power-good open-drain | Signals valid output (92–110% of 1.8V); requires external pullup ≤5.5V; sinks 1mA max for rail sequencing. |
| SW | Power switch node | Connects to 0.24μH inductor; carries high di/dt; requires tight layout with minimal loop area to reduce EMI. |
| FB | Feedback reference | Internally tied to 1.8V output; no external resistor divider needed - simplifies layout and improves noise immunity. |
| GND | Power ground | Primary return path for power stage and control circuitry; must be connected to solid thermal pad under package for optimal thermal performance. |
Key Features
| Feature | Design Value |
|---|---|
| DCS-Control topology | Enables seamless PWM-to-PFM transition with no output voltage glitch - critical for noise-sensitive RF and imaging subsystems. |
| Active output discharge | Internally discharges VOUT through SW pin during shutdown - prevents floating bias on downstream logic and ensures clean power-down sequencing. |
| 100% duty cycle operation | Maintains regulation down to VIN = VOUT + IOUT×26mΩ - maximizes usable battery voltage in portable devices. |
| 4MHz fixed-frequency PWM | Allows smallest possible passive components while maintaining tight output ripple (<15mVPP) across full load range. |
| Thermal and hiccup protection | Shuts down at 150°C junction temp and enters auto-retry mode after short-circuit - protects PCB and system during fault conditions. |

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 0.3mm height YWC package - 0.2mm lower than YFP; identical pinout and thermal metrics differ (RθJA = 130.9°C/W). | Better suited for ultra-thin embedded designs where board thickness is limited to <0.4mm above substrate. | Select YWC if mechanical height is primary constraint; verify PCB reflow profile compatibility with thinner dielectric layer. |
| TPS6208812YFPR | Identical YFP package and DCS-Control architecture but fixed 1.2V output; same 3A rating, 4MHz, and 1% accuracy. | Targeted at digital core rails (e.g., FPGA I/O banks, MCU cores) instead of 1.8V interface/I/O supplies. | Use only when 1.2V is required; not a functional substitute for 1.8V systems due to non-adjustable output. |
Compared with TPS6208818YFPR, the YWC variant offers reduced height at marginally higher thermal resistance, while the 1.2V version serves distinct voltage domains - neither provides pin-compatible replacement without schematic revision.

FAQ
What is the maximum continuous output current of the TPS6208818YFPR?
The TPS6208818YFPR delivers up to 3A continuous output current when operated within its recommended junction temperature range (–40°C to 125°C). At sustained 3A loads, lifetime reliability requires keeping TJ ≤85°C for the YFP package; thermal design must account for its 141.3°C/W RθJA.
Does the TPS6208818YFPR require external feedback resistors?
No, the TPS6208818YFPR does not require external feedback resistors because it is a fixed 1.8V output device. The FB pin is internally connected to the regulated output, eliminating the need for an external resistor divider and reducing layout sensitivity to noise and parasitic capacitance.
What package type does the TPS6208818YFPR use, and what are its dimensions?
The TPS6208818YFPR uses the YFP package - a 6-pin DSBGA (Die Size Ball Grid Array) wafer chip-scale package measuring 0.8mm × 1.2mm × 0.5mm (nominal height). It features 0.4mm ball pitch and is qualified for PCB embedding per TI's embedded power guidelines.
How does the power-good (PG) pin function on the TPS6208818YFPR?
The PG pin on the TPS6208818YFPR is an open-drain output that asserts high-impedance when VFB is between 92% and 110% of 1.8V (i.e., 1.656V–1.98V), and pulls low otherwise. It requires an external pullup resistor to ≤5.5V and can sink up to 1mA - commonly used for power-rail sequencing with other converters.
Can the TPS6208818YFPR operate in 100% duty cycle mode, and why is this important?
Yes, the TPS6208818YFPR supports 100% duty cycle operation, where the high-side FET remains fully on and the low-side FET stays off. This allows regulation down to VIN ≈ VOUT + IOUT×26mΩ - extending usable battery voltage range in portable devices and maximizing runtime before brownout.
