Product details
Overview
TPS612592YFFT from Texas Instruments is a 5.2-V, 1.5-A peak synchronous step-up DC-DC converter in a 9-pin DSBGA package, operating at 3.5 MHz with 93% efficiency, ±2% output voltage accuracy, and 21-µA standby quiescent current - designed for Li-ion-powered USB charging ports and audio amplifier biasing in smartphones.
For engineers reviewing the TPS612592YFFT datasheet, TPS612592YFFT pinout, TPS612592YFFT application, or TPS612592YFFT equivalent, key selection considerations include its 2.65–4.8-V input range, true load disconnect during shutdown (<1-µA ISD), pre-bias capability (BP pin), and minimal external component count (3 passive parts) enabling <25-mm² total solution size.
Technical Context
The TPS612592YFFT employs valley-current-mode quasi-constant-on-time PWM control for stable regulation across line and load variations, transitioning to PFM at light loads to sustain high efficiency down to 100 µA. Its integrated 170-mΩ high-side and 100-mΩ low-side MOSFETs support up to 1500 mA peak output at 5.2 V with VIN ≥ 3.3 V.
Device operation includes three distinct modes: boost (EN = high, BP = low), standby (EN = low, BP = high) delivering ~150 mA at VIN-level bias with 21-µA IQ, and true shutdown (EN = low, BP = low) with <1-µA input leakage and full load disconnect - all managed via dedicated EN and BP pins without external logic.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.2 V (±2% DC accuracy over temperature and load) |
| Input Voltage Range | 2.65 V to 4.8 V - supports single-cell Li-ion batteries down to end-of-discharge |
| Peak Output Current | 1500 mA at VOUT = 5.2 V, VIN ≥ 3.3 V - enables high-pulse USB 5V port delivery |
| Switching Frequency | 3.5 MHz - allows use of sub-1-µH inductors and compact ceramic capacitors |
| Quiescent Current | 21 µA in standby mode - extends battery life during audio amplifier biasing |
| Shutdown Current | 0.85–5.0 µA - ensures negligible drain during system sleep states |
| Efficiency | 93% at 3.5-MHz operation and moderate load - minimizes thermal rise in space-constrained phones |
| Package | 9-pin DSBGA (1.206 mm × 1.306 mm) - ultra-small footprint for thin mobile PCBs |
Pinout & Package
TPS612592YFFT uses a 9-pin NanoFree™ DSBGA (YFF) package measuring 1.206 mm × 1.306 mm with 0.4-mm pitch. Pin assignment follows TI's standard TPS6125x layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| BP (C3) | Bypass/Mode Select | Configures standby (BP = high) for VIN-level biasing or shutdown (BP = low); must be terminated - not floating |
| EN (B3) | Enable Control | Active-high digital enable; drives device into boost mode when high, disables output when low |
| GND (C1, C2) | Power Ground | Dual ground pins reduce impedance and improve thermal dissipation in CSP package |
| SW (B1, B2) | Switch Node | Internal power MOSFET drain connection; requires low-ESR ceramic capacitor and tight layout for EMI control |
| VIN (A3) | Input Supply | Accepts 2.65–4.8 V; connects directly to battery or intermediate rail with local 4.7-µF decoupling |
| VOUT (A1, A2) | Regulated Output | Delivers fixed 5.2 V; dual pins reduce trace resistance and support >1-A continuous loading |
Key Features
| Feature | Design Value |
|---|---|
| Light-load PFM mode | Maintains >85% efficiency down to 100 µA load - critical for always-on audio subsystems |
| Selectable standby mode | Enables VIN-referenced biasing (≤150 mA) with 21-µA IQ - powers Class-D amplifiers without full regulation |
| True load disconnect | Breaks VOUT-to-VIN path during shutdown (EN = BP = low) - prevents backfeed and leakage in shared-rail systems |
| Thermal & overload protection | Auto-shutdown at 140°C junction with 20°C hysteresis - ensures reliability under sustained 1.5-A pulse loads |
| Minimal external components | Requires only 1 µH inductor, 4.7-µF input cap, and 10-µF output cap - reduces BOM cost and board area |
Applications
| USB Charging Port | Smartphone Audio Biasing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-up converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS61258YFFT | Fixed 4.5-V output; higher 1500-mA peak rating at VIN ≥ 3.3 V; identical package and pinout | Targeted for 4.5-V USB OTG or lower-voltage audio rails - not suitable for 5.2-V USB-C PD sink compliance | Select when system requires 4.5-V regulation and shares same PCB layout; verify VOUT tolerance against load transient specs. |
| MT9700-52 | 5.2-V output; 1.2-A continuous (vs 1.5-A peak); 2.7–5.5-V input; 2.1-MHz switching; SOT-23-6 package | Larger footprint and lower peak current limit; lacks standby mode and true load disconnect | Use where cost sensitivity outweighs size and feature requirements; not recommended for smartphone audio biasing. |
Compared with TPS61258YFFT, the TPS612592YFFT provides +0.7-V higher output for USB-C compatibility but trades 100-mA peak current headroom; versus MT9700-52, it delivers superior integration (standby mode, load disconnect, smaller CSP), albeit at higher unit cost and TI-specific supply chain dependency.

FAQ
What is the fixed output voltage of the TPS612592YFFT?
The TPS612592YFFT provides a factory-trimmed fixed output voltage of 5.2 V with ±2% total DC accuracy across temperature, line, and load conditions. This value is confirmed in the Electrical Characteristics table (Section 7.5) of the SLVSAG8G datasheet, where VOUT is specified as 5.1 V (min), 5.2 V (typ), and 5.3 V (max) under open-loop PWM operation at VIN ≥ 2.7 V.
Does the TPS612592YFFT support true load disconnect during shutdown?
Yes, the TPS612592YFFT supports true load disconnect when both EN and BP pins are driven low. In this configuration, the internal power switches fully isolate VOUT from VIN, limiting shutdown current to 0.85–5.0 µA and preventing backfeed - a requirement verified in Section 7.5 (ISD parameter) and functional mode descriptions (Section 9.4) of the official datasheet.
What is the minimum input voltage required for 1500-mA peak output from the TPS612592YFFT?
The TPS612592YFFT requires VIN ≥ 3.3 V to deliver its rated 1500-mA peak output current at 5.2 V. This condition is explicitly stated in the Device Options table (Section 5) and confirmed in Figure 12 (Maximum Output Current vs Input Voltage), where 1500 mA is achievable only above 3.3 V across all temperatures.
Can the TPS612592YFFT operate in standby mode to bias an audio amplifier?
Yes, the TPS612592YFFT enters standby mode when EN = low and BP = high, sourcing up to ~150 mA at VIN-level voltage with only 21 µA quiescent current. This mode is documented in Section 6 (Pin Functions), Section 9.4 (Device Functional Modes), and Figure 25 (Parameter Measurement Schematic) of the SLVSAG8G datasheet.
What package type and dimensions does the TPS612592YFFT use?
The TPS612592YFFT uses a 9-pin DSBGA (NanoFree™) package designated YFF, with nominal body dimensions of 1.206 mm × 1.306 mm and 0.4-mm ball pitch. This is confirmed in the Device Information table (page 1), Package Summary (Section 14.1), and mechanical drawings in the SLVSAG8G datasheet.
