Product details
Overview
TPS62088YFPT from Texas Instruments is a 2.4V to 5.5V input, 3-A 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, and 1% output voltage accuracy. It delivers high efficiency up to 95% with 26mΩ internal high- and low-side MOSFETs for compact power delivery in space-constrained embedded systems.
For engineers reviewing the TPS62088YFPT datasheet, TPS62088YFPT pinout, TPS62088YFPT application, or TPS62088YFPT equivalent, this device supports PFM/PWM operation mode, active output discharge, power-good signaling, and seamless light-load efficiency optimization - critical for battery-powered portable electronics requiring minimal footprint and ultra-low quiescent current (4µA).
Technical Context
The TPS62088YFPT implements TI's DCS-Control architecture, combining adaptive constant-on-time PWM regulation with discontinuous conduction mode (DCM) power-save operation to maintain >90% efficiency from 1mA to 3A load. Its 4MHz fixed-frequency PWM mode ensures tight output voltage regulation (±1%) and excellent transient response without external compensation.
It integrates dual 26mΩ MOSFETs, supports 100% duty-cycle low-dropout operation down to VIN – VOUT ≈ 100mV at light loads, and features integrated thermal shutdown (150°C), hiccup-mode short-circuit protection, and undervoltage lockout (2.2V nominal) - all within a 0.5mm-thick 6-pin DSBGA package optimized for embedding beneath PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.4V to 5.5V - supports single-cell Li-ion, Li-polymer, and multi-cell alkaline/NiMH batteries without pre-regulation. |
| 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-0.3µH inductors and <22µF ceramic output capacitors, reducing solution size to <12mm². |
| Quiescent Current | 4 µA - extends battery runtime in always-on sensor nodes and standby modes without compromising wake-up speed. |
| Output Accuracy | ±1% - ensures reliable core voltage compliance for ARM Cortex-A/M series processors and DDR I/O rails. |
| Package | 6-pin YFP (DSBGA, 0.4mm pitch) - 0.8mm × 1.2mm × 0.5mm body enables embedded PCB integration and <0.6mm system height. |
| Thermal Protection | 150°C junction shutdown with 20°C hysteresis - prevents thermal runaway during sustained 3A operation in confined enclosures. |
Pinout & Package
TPS62088YFPT uses a 6-pin wafer-level chip-scale package (YFP, DSBGA) with 0.4mm pitch and 0.5mm height. The package is designed for board embedding and ultra-thin applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN | Enable input | Active-high logic control; threshold ~0.89V (rising); must be pulled high to activate regulator - no floating allowed. |
| VIN | Input voltage supply | Accepts 2.4–5.5V; requires local 4.7µF ceramic decoupling placed adjacent to pin for stable high-frequency operation. |
| PG | Power-good open-drain output | Signals valid output (96–105% VFB) with 1mA sink capability; requires external pullup ≤5.5V for rail sequencing. |
| SW | Switch node | Connects to external 0.24µH inductor; carries high di/dt PWM current - demands tight layout and thermal relief to GND plane. |
| FB | Feedback input | Senses output via resistor divider (or direct connection for fixed-VOUT variants); reference voltage = 600mV ±1%. |
| 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 transition between PWM and power-save modes without output voltage disturbance - critical for RF-sensitive applications like camera modules. |
| Active output discharge | Internally discharges VOUT through SW pin when EN is low, preventing floating outputs and ensuring safe power-down sequencing. |
| Forced-PWM option available | TPS62088AYFPT variant maintains CCM across full load range - eliminates audible noise and reduces EMI variability in noise-critical audio subsystems. |
| 100% duty-cycle operation | Extends usable battery range by sustaining regulation down to VIN ≈ VOUT + IOUT×RDS(on), maximizing runtime in deep-discharge states. |
| Hiccup short-circuit protection | Enters 128µs auto-restart cycle after 32 overcurrent events - protects against sustained shorts without latch-off, enabling robust field operation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS6208818YFPT | Fixed 1.8V output; no FB resistor divider required; includes internal feedforward capacitor. | Eliminates external R1/R2/C4 components - reduces BOM count and layout area for fixed-voltage designs. | Select when 1.8V output is required and design simplicity outweighs adjustable flexibility. |
| TPS62088AYFPT | Forced-PWM operation only; no automatic PFM mode; higher quiescent current (8mA typical). | Ensures constant 4MHz switching - preferred for EMI-controlled environments and noise-sensitive analog circuits. | Select when deterministic frequency and minimal output ripple are mandatory, even at light loads. |
Compared with TPS62088YFPT, TPS6208818YFPT simplifies design for fixed 1.8V rails but sacrifices adjustability, while TPS62088AYFPT trades light-load efficiency for predictable EMI behavior - making TPS62088YFPT the balanced choice for dynamically loaded, battery-sensitive systems.

FAQ
What is the maximum continuous output current supported by the TPS62088YFPT?
The TPS62088YFPT supports 3 A continuous output current across its operating junction temperature range (–40°C to 125°C). At full 3-A load, lifetime reliability requires maintaining junction temperature below 85°C - achieved via proper PCB thermal design using the exposed GND pad and recommended copper area per TI's thermal guidelines.
Does the TPS62088YFPT require external feedback resistors to set output voltage?
Yes, the TPS62088YFPT is an adjustable-output converter and requires an external resistor divider on the FB pin to set VOUT between 0.6V and 4.0V. The feedback reference voltage is 600mV ±1%, and R2 should be ≤100kΩ to ensure sufficient divider current (≥0.6µA) for noise immunity and accuracy.
What package type and dimensions does the TPS62088YFPT use?
The TPS62088YFPT uses the YFP package: a 6-pin wafer chip-scale package (DSBGA) with nominal dimensions of 0.8mm × 1.2mm × 0.5mm and 0.4mm ball pitch. It features a bottom-side thermal pad connected to GND, enabling efficient heat transfer to the PCB for high-current operation.
How does the power-good (PG) pin function on the TPS62088YFPT?
The PG pin on the TPS62088YFPT is an open-drain output that goes high-impedance when VFB is between 96% and 105% of nominal (e.g., 576–630mV for 600mV reference), and pulls low when outside that window. It sinks up to 1mA and requires an external pullup to ≤5.5V - commonly used for power-rail sequencing with other converters' EN pins.
Can the TPS62088YFPT operate with input voltage as low as 2.4V while delivering 3A output?
Yes, the TPS62088YFPT operates across 2.4V to 5.5V input and sustains 3A output down to VIN = 2.4V, provided thermal limits are respected. At low input, 100% duty-cycle mode engages to maintain regulation - though minimum input for 3A at 1.8V output is ~2.05V (calculated using VIN,MIN = VOUT + IOUT×RDS(on)).
