Product details
Overview
TPS6208812YFPR from Texas Instruments is a 2.4V–5.5V input, 1.2V fixed-output, 3A synchronous step-down DC/DC converter in a 0.8mm × 1.2mm × 0.5mm wafer chip-scale package (YFP). It features DCS-Control topology, 4MHz switching frequency, 1% output voltage accuracy, and 4μA quiescent current-designed for space-constrained embedded power rails in camera modules and optical modules.
For engineers reviewing the TPS6208812YFPR datasheet, TPS6208812YFPR pinout, TPS6208812YFPR application, or TPS6208812YFPR equivalent, key selection considerations include its 6-pin WCSP footprint, 100% duty cycle low-dropout capability, active output discharge, power-good signal, and PFM/PWM hybrid operation mode for high light-load efficiency.
Technical Context
The TPS6208812YFPR implements TI's DCS-Control topology-combining adaptive constant-on-time PWM with seamless transition into power-save mode-enabling stable regulation across 0–3A load while maintaining 4MHz nominal switching frequency. Its internal 26mΩ/26mΩ MOSFET pair supports high-efficiency conversion at up to 95% peak efficiency.
It operates across –40°C to +125°C junction temperature, integrates undervoltage lockout (2.2V threshold), thermal shutdown (150°C), hiccup short-circuit protection, and soft-start (1.25ms). The fixed 1.2V output eliminates external feedback resistors, simplifying layout for ultra-compact designs under 0.6mm height.
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 1.2 V ±1% - eliminates feedback resistor network, reduces BOM count and layout area. |
| Max Output Current | 3 A continuous - enables direct powering of core logic, FPGA I/O banks, or ASIC domains in wearables and SSDs. |
| Switching Frequency | 4 MHz - permits use of sub-0.3 µH inductors and 10 µF ceramic output capacitors for <12 mm² total solution size. |
| Quiescent Current | 4 µA - extends battery runtime in always-on sensor nodes and standby modes of portable devices. |
| Package | 6-pin YFP (DSBGA) - 0.8 mm × 1.2 mm × 0.5 mm wafer chip-scale package with 0.4 mm pitch, optimized for embedding. |
| Efficiency | Up to 95% - achieved via low RDS(on) 26 mΩ high- and low-side MOSFETs and DCS-Control transient response. |
Pinout & Package
TPS6208812YFPR uses a 6-pin wafer chip-scale package (YFP, DSBGA) measuring 0.8 mm × 1.2 mm × 0.5 mm with 0.4 mm ball pitch. The package is designed for board embedding and ultra-low-profile applications (<0.6 mm height).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN | Enable input | Active-high logic control; requires ≥1.0 V to enable; must not be left floating. |
| VIN | Input voltage supply | Accepts 2.4–5.5 V; connects to input capacitor near package for low-impedance path. |
| PG | Power-good open-drain output | Signals valid output regulation (96–105% of 1.2 V); requires external pullup ≤5.5 V. |
| SW | Switch node | Connects to inductor; carries high-frequency pulsed current; requires tight loop layout. |
| FB | Feedback input | Internally tied to 1.2 V output; no external resistor divider required for fixed-output version. |
| GND | Ground reference | Primary return path for power and control circuits; must be connected to solid ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| DCS-Control topology | Enables seamless PWM-to-power-save mode transition with <1% output voltage deviation and minimal ripple during load transients. |
| 100% duty cycle operation | Extends battery life by sustaining regulation down to VIN ≈ VOUT + IOUT×RDS(on), critical for deep-discharge Li-ion use cases. |
| Active output discharge | Internally discharges VOUT through SW pin when EN is low, preventing floating rail conditions in multi-rail sequencing. |
| Power-good (PG) output | Provides system-level power sequencing and fault monitoring with 100 µs blanking time on rising edge and 20 µs deglitch on falling edge. |
| Hiccup short-circuit protection | Disables switching after 32 overcurrent events, then auto-restarts after 128 µs-prevents thermal runaway during sustained faults. |
Applications
| Camera Modules | Optical Modules |
|---|---|
Use Scenario: Powering image sensor analog front-end and ISP core logic in smartphone rear cameras. IC Role / Device Role / Timing Role: Primary 1.2 V core supply delivering clean, low-noise power with fast transient response to handle burst-mode pixel readout.

IC Role / Device Role / Timing Role: High-current, thermally robust DC/DC converter supporting burst write workloads and idle power states. Use Value: 3 A capability handles peak controller current; 4 μA quiescent current minimizes standby leakage in host-sleep modes. | Use Scenario: Powering ultra-low-profile PMIC subsystems in smartwatches and hearables with strict height constraints. IC Role / Device Role / Timing Role: Embedded point-of-load regulator enabling <0.6 mm total module height and 12 mm² PCB area.

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS6208812YWC | Same electrical specs but in 0.3 mm tall YWC (DSBGA) package; lower thermal resistance (RθJB = 27.3°C/W vs. 47.3°C/W). | Better suited for embedded or ultra-low-profile applications where height <0.4 mm is mandatory. | Select YWC if board embedding or thermal performance under 3 A continuous load is prioritized. |
| TPS6209712YFPR | Pin-compatible 3A buck with 2.5V–5.5V input, 1.2V fixed output, but uses different control scheme (adaptive on-time) and higher IQ (12 µA). | Higher quiescent current limits battery life in always-on wearables; lacks active output discharge and PG pin. | Choose only if legacy design reuse or specific EMI profile requirements favor TPS62097 over DCS-Control architecture. |
Compared with TPS6208812YFPR, the YWC variant offers superior thermal performance and reduced height for embedded use, while TPS6209712YFPR trades DCS-Control benefits for simpler control at the cost of missing key system features like PG and active discharge.

FAQ
What is the maximum continuous output current supported by the TPS6208812YFPR?
The TPS6208812YFPR supports up to 3 A of continuous output current across its operating junction temperature range (–40°C to +125°C). At full 3 A load with ambient temperatures above 85°C, lifetime derating applies per TI's recommended operating conditions-designers should verify thermal performance using the YFP package's RθJA of 141.3°C/W and ensure adequate PCB copper area or airflow.
Does the TPS6208812YFPR require external feedback resistors to set the output voltage?
No, the TPS6208812YFPR does not require external feedback resistors. It is a fixed-output variant with an internally trimmed 1.2 V regulation point; the FB pin is internally connected to the output and must be directly tied to VOUT. This eliminates resistor matching errors, saves PCB area, and improves noise immunity compared to adjustable versions.
What protection features are integrated into the TPS6208812YFPR?
The TPS6208812YFPR integrates thermal shutdown (150°C trip, 130°C hysteresis), hiccup-mode short-circuit protection (32-event lockout with 128 µs auto-restart), undervoltage lockout (2.2 V threshold), active output discharge, and power-good monitoring. These features enable robust operation in unattended or safety-critical embedded systems without external supervision circuitry.
Can the TPS6208812YFPR operate in forced PWM mode?
No, the TPS6208812YFPR operates in automatic PFM/PWM mode only. Forced-PWM functionality is exclusive to the "A" variants (e.g., TPS62088AYFPR). The TPS6208812YFPR enters power-save mode at light loads to minimize quiescent current (4 µA), making it optimal for battery-powered applications where efficiency across the full load range is essential.
What is the purpose of the PG (power-good) pin on the TPS6208812YFPR?
The PG pin on the TPS6208812YFPR is an open-drain output that signals valid regulation of the 1.2 V output-asserting high-impedance when VFB is between 96% and 105% of nominal (1.152 V to 1.26 V), and pulling low outside that window. It enables reliable power sequencing with other rails and fault detection, requiring only a simple external pullup resistor to any voltage ≤5.5 V.
