Product details
Overview
TPS62088YFPR from Texas Instruments is a 2.4V–5.5V input, 3A synchronous step-down DC/DC 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. It delivers high efficiency up to 95% with 4μA quiescent current and supports embedded power rails in space-constrained SSDs and camera modules.
For engineers reviewing the TPS62088YFPR datasheet, TPS62088YFPR pinout, TPS62088YFPR application, or TPS62088YFPR equivalent, key selection considerations include its 6-pin WCSP footprint, PFM/PWM operation mode, active output discharge, power-good signal, and thermal shutdown protection for battery-powered portable systems.
Technical Context
The TPS62088YFPR implements DCS-Control architecture-combining adaptive constant-on-time PWM for medium/heavy loads and seamless transition into power-save mode at light loads-enabling stable regulation with minimal output ripple across 0.6V–4.0V output range. Its 26mΩ/26mΩ internal MOSFET pair and 4MHz fixed-frequency operation allow use of sub-0.3µH inductors and <10mm² total solution size.
It operates in PFM/PWM hybrid mode (not forced-PWM), includes undervoltage lockout (2.2V threshold), 100% duty-cycle low-dropout capability, soft-start (1.25ms), and hiccup-mode short-circuit protection triggered after 32 overcurrent events. The open-drain PG pin provides ±2% windowed power-good signaling with 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 3.3V/5V rail inputs without external LDO pre-regulation. |
| Output Current | 3 A continuous - rated for sustained 3A load at junction temperature ≤85°C in YFP package; lifetime derating applies above that temperature. |
| Switching Frequency | 4 MHz - enables use of ultra-small 0.24 µH inductors and compact ceramic output capacitors (e.g., 2×10 µF). |
| Quiescent Current | 4 µA - ensures >100-hour standby in always-on wearable sensors or IoT edge nodes powered by coin cells. |
| Output Accuracy | ±1% - guarantees tight regulation for core logic (e.g., 1.8V FPGA I/O, 1.2V processor cores) without external trimming. |
| Efficiency Peak | Up to 95% - achieved at mid-load (e.g., 1A @ 1.8V out, 3.3V in), minimizing thermal rise in sealed enclosures. |
| Package | YFP (DSBGA-6), 0.8mm × 1.2mm × 0.5mm - 0.4mm pitch wafer-level CSP optimized for embedding beneath PCB or in stacked SiP assemblies. |
Pinout & Package
TPS62088YFPR uses a 6-pin DSBGA (Wafer Chip Scale Package) with 0.4mm pitch and nominal body size 0.8mm × 1.2mm × 0.5mm. The package is designed for board embedding and ultra-low-profile (<0.6mm) applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN | Enable input | Active-high logic control (VIH = 1.0V min); must be pulled high to activate regulator; floating prohibited. |
| VIN | Input voltage supply | Accepts 2.4–5.5V; requires local 4.7µF ceramic decoupling placed adjacent to pin. |
| PG | Power-good open-drain output | Sinks up to 1mA; requires external pullup (≤5.5V); signals valid output when FB reaches 96–105% of target. |
| SW | Switch node | Connects to external 0.24µH inductor; carries high di/dt; requires tight layout to minimize EMI and voltage spikes. |
| FB | Feedback input | Monitors output via resistor divider (or direct connection for fixed-VOUT variants); 600mV reference sets VOUT = 600mV × (1 + R1/R2). |
| GND | Ground reference | System ground return for control circuitry and power stage; must be low-impedance, thermally coupled to PCB copper pour. |
Key Features
| Feature | Design Value |
|---|---|
| DCS-Control topology | Enables seamless PWM-to-power-save mode 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, preventing residual voltage hold-up that could interfere with system reset sequencing. |
| 100% duty cycle operation | Extends battery runtime by maintaining regulation down to VIN ≈ VOUT + (IOUT × RDS(on)), e.g., 1.82V input sustains 1.8V output at 3A. |
| Hiccup short-circuit protection | Limits fault energy by disabling switching for 128µs after 32 consecutive current-limit events-protects IC and PCB traces during sustained overload. |
| Thermal shutdown with hysteresis | Shuts down at 150°C junction temperature and auto-recovers only after cooling by ≥20°C-prevents thermal runaway in confined layouts. |
Applications
| Solid-State Drives (SSDs) | Wearable Products |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62088YWC | Same electrical specs but in thinner 0.3mm YWC package; identical pinout and thermal performance per mm². | Better suited for embedded die-stacking or ultra-low-profile (<0.4mm) designs where Z-height is critical. | Select YWC if board thickness budget is <0.6mm and thermal margin allows reduced case-to-board conduction path. |
| TPS6208818YFP | Fixed 1.8V output version; eliminates FB resistor divider; same YFP package and 3A rating. | Reduces BOM count and layout area for dedicated 1.8V rails-no need for external feedback network or feedforward capacitor. | Choose TPS6208818YFP when output voltage is fixed and design prioritizes component count reduction over adjustability. |
Compared with TPS62088YFPR, TPS62088YWC offers identical regulation performance in a lower-profile package ideal for embedded applications, while TPS6208818YFP simplifies design for fixed 1.8V use cases by removing external feedback components-both retain full 3A capability and DCS-Control benefits.

FAQ
What is the maximum continuous output current of the TPS62088YFPR?
The TPS62088YFPR is rated for 3 A continuous output current under recommended operating conditions. However, TI specifies that lifetime reliability is reduced when operating continuously at 3 A with junction temperature exceeding 85°C in the YFP package. Derating or enhanced thermal management is advised for sustained high-current operation.
Does the TPS62088YFPR support fixed-output voltage configurations?
No-the TPS62088YFPR is the adjustable-output variant of the family and requires an external resistor divider on the FB pin to set VOUT between 0.6V and 4.0V. Fixed-output versions such as TPS6208818YFP (1.8V) or TPS6208833YFP (3.3V) are separate orderable part numbers with internal feedback networks.
What is the purpose of the PG (power-good) pin on the TPS62088YFPR?
The PG pin on the TPS62088YFPR is an open-drain output that signals valid regulation: it goes high-impedance when FB voltage is within 96–105% of target, and pulls low when outside that window (e.g., during startup, dropout, or fault). It requires an external pullup resistor and is commonly used for power-rail sequencing with other converters.
Can the TPS62088YFPR operate in forced-PWM mode?
No-the TPS62088YFPR operates in automatic PFM/PWM hybrid mode. Forced-PWM operation is exclusive to the TPS62088AYFP and TPS62089AYFP variants, which maintain continuous conduction mode across all loads to minimize output ripple-use those parts if CCM is mandatory for your application.
What package type does the TPS62088YFPR use, and what are its mechanical dimensions?
The TPS62088YFPR uses the YFP package: a 6-pin DSBGA (Die Size Ball Grid Array) with wafer-level chip-scale construction. Its nominal dimensions are 0.8mm × 1.2mm × 0.5mm (L × W × H), with 0.4mm ball pitch-designed for embedding and ultra-thin PCB assemblies.
