Product details
Overview
TPS62088AYFPR 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), featuring DCS-Control topology, 4MHz switching frequency, 1% output voltage accuracy, and 4μA quiescent current - designed for space-constrained embedded power rails in portable electronics.
For engineers reviewing the TPS62088AYFPR datasheet, TPS62088AYFPR pinout, TPS62088AYFPR application, or TPS62088AYFPR equivalent, this device supports PFM/PWM auto-transition, active output discharge, power-good signaling, and 100% duty-cycle operation - critical for battery-powered systems requiring ultra-low height (<0.6mm), high efficiency across load range, and seamless light-load regulation.
Technical Context
The TPS62088AYFPR implements DCS-Control architecture with adaptive constant-on-time PWM modulation and seamless transition into power-save mode, enabling stable regulation without external compensation. It integrates matched 26mΩ high-side and low-side MOSFETs and operates at a fixed 4MHz nominal switching frequency to minimize external component size.
Its functional modes include enable-controlled startup with 1.25ms soft-start, open-drain power-good output with 92–110% voltage window detection, thermal shutdown at 150°C with 20°C hysteresis, and hiccup-mode short-circuit protection triggered after 32 current-limit events - all optimized for compact, thermally constrained PCB layouts.
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 multi-cell alkaline/NiMH battery inputs. |
| Output Current | 3 A continuous - enables direct powering of SoCs, FPGAs, and memory subsystems in wearables and SSDs. |
| Switching Frequency | 4 MHz - allows use of sub-0.3 µH inductors and 0402/0603 ceramic capacitors for <12 mm² total solution size. |
| Quiescent Current | 4 µA - sustains >100-hour standby in always-on sensor nodes without compromising light-load efficiency. |
| Output Accuracy | ±1% - ensures reliable core voltage regulation for ARM Cortex-A/M series processors and DDR I/O interfaces. |
| Package Dimensions | 0.8 mm × 1.2 mm × 0.5 mm WCSP (YFP) - embeddable under connectors or displays with 0.4 mm pitch and 0.3 mm standoff clearance. |
| Thermal Resistance | RθJA = 141.3 °C/W - requires minimal copper area for thermal relief in 2-layer handheld PCBs. |
Pinout & Package
TPS62088AYFPR 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 and bottom-solder ball termination. The package is designed for embedding beneath components and supports <0.6 mm system height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN | Enable input | Active-high logic control (VIH = 1.0 V min); must be pulled high to activate regulator; floating prohibited. |
| VIN | Power input | Primary input rail connection (2.4–5.5 V); requires local 4.7 µF ceramic decoupling placed adjacent to pin. |
| PG | Power-good open-drain output | Signals valid output (92–110% of VOUT) with 1 mA sink capability; requires external pullup ≤5.5 V. |
| SW | Switch node | Connection to external inductor; carries high di/dt switching current; must be routed with minimal loop area. |
| FB | Feedback input | Resistive divider input for adjustable output (0.6–4.0 V); internal reference = 600 mV ±1%. |
| GND | Ground reference | System ground return path; must be connected to solid thermal pad under package for optimal thermal performance. |
Key Features
| Feature | Design Value |
|---|---|
| DCS-Control topology | Enables simultaneous high DC accuracy, fast transient response (<10 µs settling), and seamless PWM-to-PFM mode transition without output voltage glitch. |
| 100% duty-cycle operation | Extends battery runtime by maintaining regulation down to VIN ≈ VOUT + (IOUT × RDS(on)), e.g., 1.8 V output sustained from 2.0 V input at 3 A. |
| Active output discharge | Internally discharges VOUT via SW pin when EN = LOW, preventing floating rail conditions during sequencing or fault recovery. |
| Forced-PWM mode | Eliminates frequency variation and output ripple increase at light loads - essential for noise-sensitive RF and audio subsystems. |
| Hiccup short-circuit protection | Shuts down for 128 µs after 32 overcurrent events, limiting average power dissipation during sustained overload or output short. |
Applications
| Solid-State Drives | 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 |
|---|---|---|---|
| TPS62088YFPR | PFM/PWM auto-transition mode; same 3 A rating, YFP package, and 4 MHz frequency but lacks forced-PWM operation. | Higher light-load efficiency but increased output ripple and variable frequency - unsuitable for RF-sensitive designs. | Select when lowest quiescent current (4 µA) and maximum light-load efficiency are prioritized over EMI control. |
| TPS6208818YFPR | Fixed 1.8 V output; identical package, thermal specs, and DCS-Control architecture but no FB pin or external resistor network required. | Reduces BOM count by 2 resistors and 1 capacitor; eliminates feedforward cap design risk but forfeits output voltage flexibility. | Select when system requires only 1.8 V and layout simplicity outweighs need for programmability. |
Compared with TPS62088YFPR, TPS62088AYFPR trades light-load efficiency for deterministic 4 MHz operation and lower noise - critical for camera/RF subsystems; versus TPS6208818YFPR, it adds design flexibility at the cost of two external resistors and careful feedback network layout.

FAQ
What is the maximum continuous output current supported by the TPS62088AYFPR?
The TPS62088AYFPR supports 3 A continuous output current across its operating junction temperature range of –40°C to 125°C. At 3 A, thermal derating applies above 85°C junction temperature for the YFP package; design margin should include RθJA = 141.3 °C/W and appropriate PCB copper area to maintain safe operating temperature.
Does the TPS62088AYFPR require an external feedback resistor network?
Yes, the TPS62088AYFPR is an adjustable-output version and requires an external resistor divider on the FB pin to set VOUT between 0.6 V and 4.0 V. The internal reference is 600 mV ±1%, and R2 should be ≤100 kΩ for noise immunity; a 120 pF feedforward capacitor across R1 is also required per TI design guidelines.
How does the power-good (PG) pin function on the TPS62088AYFPR?
The PG pin on the TPS62088AYFPR is an open-drain output that asserts high-impedance when VFB is between 96% and 105% of nominal, and pulls low when VFB falls below 92% or rises above 110%. It sinks up to 1 mA and requires an external pullup resistor to any rail ≤5.5 V for proper sequencing with other power supplies.
Can the TPS62088AYFPR operate with a 2.4 V input and 1.8 V output at full 3 A load?
Yes, the TPS62088AYFPR supports 100% duty-cycle operation, enabling regulation at VIN as low as VOUT + (IOUT × RDS(on)). With 26 mΩ high-side RDS(on), it maintains 1.8 V output at 3 A with VIN ≥ 1.8 V + (3 A × 0.026 Ω) = 1.878 V - well within its 2.4 V minimum input specification.
What package type and dimensions does the TPS62088AYFPR use?
The TPS62088AYFPR uses a 6-pin DSBGA wafer chip-scale package designated YFP, with nominal body dimensions of 0.8 mm × 1.2 mm × 0.5 mm and 0.4 mm ball pitch. It features solder balls on the bottom surface and is optimized for embedding beneath components in ultra-thin devices.
