Product details
Overview
TPS6208833YFPR from Texas Instruments is a 3-A, fixed 3.3-V synchronous step-down converter in a 0.8mm × 1.2mm × 0.5mm wafer chip-scale package (YFP), featuring DCS-Control topology, 4 MHz switching frequency, 1% output voltage accuracy, and 4 µA quiescent current - designed for space-constrained battery-powered systems such as camera modules and optical modules.
For engineers reviewing the TPS6208833YFPR datasheet, TPS6208833YFPR pinout, TPS6208833YFPR application, or TPS6208833YFPR equivalent, key selection considerations include its 2.4V–5.5V input range, 100% duty cycle low-dropout operation, active output discharge, power-good signal, and thermal shutdown with hiccup protection - all within a 0.5mm-profile WCSP.
Technical Context
The TPS6208833YFPR implements DCS-Control architecture to enable seamless transition between PWM and power-save modes without output voltage disturbance, delivering excellent load transient response and <1% DC regulation accuracy. Its 4 MHz fixed-frequency PWM mode ensures minimal external component size, while the 100% duty cycle capability extends battery runtime by maintaining regulation down to VIN ≈ VOUT + IOUT × RDS(on).
It integrates matched 26 mΩ high-side and low-side MOSFETs, supports forced-PWM variants (not this part), and includes integrated soft-start (1.25 ms), undervoltage lockout (2.2 V ±160 mV), and open-drain power-good output with 92–110% voltage window detection - all optimized for embedded, ultra-thin portable applications requiring <0.6 mm height and ≤12 mm² PCB area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3 V ±1% (3.267–3.333 V) - eliminates external feedback resistors and reduces BOM count. |
| Max Output Current | 3 A continuous - supports high-current rails in camera ISPs and optical drivers without external current sharing. |
| Input Voltage Range | 2.4 V to 5.5 V - compatible with single-cell Li-ion, Li-polymer, and 3.3 V/5 V system rails. |
| Switching Frequency | 4 MHz nominal - enables use of sub-0.3 µH inductors and 0402/0603 ceramic capacitors for ultra-compact layouts. |
| Quiescent Current | 4 µA in PFM mode - extends battery life in always-on wearable and sensor subsystems. |
| Efficiency | Up to 95% at medium loads - minimizes thermal dissipation in sealed enclosures like smartphone camera modules. |
| Package | 6-pin YFP (DSBGA), 0.8 mm × 1.2 mm × 0.5 mm - supports embedding and <0.6 mm total solution height. |
Pinout & Package
TPS6208833YFPR uses a 6-pin wafer chip-scale package (YFP, DSBGA) with 0.4 mm pitch and 0.5 mm profile. The package is lead-free, RoHS-compliant, and optimized for solder paste printing and reflow in fine-pitch SMT assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN | Enable input | Active-high logic control (VIH = 1.0 V); must be pulled high to operate; 0.01 µA leakage enables direct MCU GPIO drive. |
| VIN | Input voltage supply | Accepts 2.4–5.5 V; requires local 4.7 µF ceramic decoupling placed adjacent to pin for stable high-frequency operation. |
| PG | Power-good open-drain output | Signals valid regulation (92–110% of 3.3 V); requires external pullup ≤5.5 V; sinks 1 mA for rail sequencing. |
| SW | Switch node | Connects to inductor; carries high di/dt; must be routed short and wide to minimize EMI and voltage spikes. |
| FB | Feedback input | Internally connected to 3.3 V 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 tied to solid thermal pad under package for optimal thermal performance. |
Key Features
| Feature | Design Value |
|---|---|
| DCS-Control topology | Enables seamless PWM-to-power-save mode transition with zero output voltage glitch - critical for noise-sensitive RF and imaging circuits. |
| 100% duty cycle operation | Maintains regulation when VIN drops to ~3.6 V at 3 A load - maximizes usable battery capacity in Li-ion systems. |
| Active output discharge | Internally discharges VOUT through SW pin when EN is low - prevents floating outputs and ensures predictable power-down sequencing. |
| Hiccup short-circuit protection | Enters 128 µs auto-restart cycle after 32 overcurrent events - protects against sustained shorts without latch-off or manual reset. |
| Thermal shutdown with hysteresis | Shuts down at 150 °C junction temperature and resumes at 130 °C - prevents thermal runaway while allowing recovery without system reset. |
Applications
| Camera Modules | Optical 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 |
|---|---|---|---|
| TPS6208833YWC | Same electrical specs but in 0.3 mm tall YWC package - 0.2 mm lower profile, identical pinout and function. | Better suited for ultra-low-height designs (<0.4 mm total), e.g., foldable display flex interposers or stacked sensor modules. | Select YWC if mechanical height is primary constraint; YFP offers slightly better thermal resistance (RθJA = 141.3°C/W vs. 130.9°C/W). |
| TPS6208818YFPR | Identical package and architecture but fixed 1.8 V output; same 3 A rating, 4 µA IQ, and DCS-Control. | Used where core logic or memory rails require 1.8 V instead of 3.3 V - not interchangeable without redesigning output network. | Choose only when 1.8 V is required; not a functional substitute for 3.3 V operation. |
Compared with TPS6208833YFPR, the YWC variant delivers identical regulation and protection features in a lower-profile package ideal for height-critical assemblies, while the 1.8 V version serves distinct voltage domains - neither is pin-compatible drop-in replacement for 3.3 V system requirements.

FAQ
What is the output voltage tolerance of the TPS6208833YFPR?
The TPS6208833YFPR has a guaranteed output voltage accuracy of ±1% over temperature and line/load conditions, corresponding to a 3.3 V nominal output ranging from 3.267 V to 3.333 V in PWM mode. This tight tolerance is achieved via internal precision feedback resistors and 600 mV reference voltage, eliminating external resistor variation and drift.
Does the TPS6208833YFPR require external feedback resistors?
No, the TPS6208833YFPR does not require external feedback resistors because it is a fixed-output variant with internal resistor divider connected to the FB pin. The FB pin must be directly connected to the output capacitor; adding external resistors would disrupt regulation and void the specified 1% accuracy.
What package type and dimensions does the TPS6208833YFPR use?
The TPS6208833YFPR uses the YFP (DSBGA) wafer chip-scale package measuring 0.8 mm × 1.2 mm × 0.5 mm with 0.4 mm ball pitch. It features six solder balls arranged in a 2×3 array and is designed for embedding and ultra-low-profile PCB assemblies.
How does the power-good (PG) pin function on the TPS6208833YFPR?
The PG pin on the TPS6208833YFPR is an open-drain output that goes high-impedance when FB voltage is between 96% and 105% of 3.3 V (i.e., 3.168–3.465 V), and pulls low when outside that window. It requires an external pullup resistor to ≤5.5 V and can sink up to 1 mA - commonly used for rail sequencing or system reset assertion.
Can the TPS6208833YFPR operate with input voltage below 3.3 V?
Yes, the TPS6208833YFPR supports input voltages as low as 2.4 V and maintains regulation down to ~3.6 V at full 3 A load via 100% duty cycle operation. Below that point, output voltage drops linearly with input; however, undervoltage lockout disables the device if VIN falls below 2.2 V (±160 mV hysteresis).
