Product details
Overview
TPS612592YFFR from Texas Instruments is a synchronous step-up DC-DC converter in 9-pin NanoFree™ DSBGA packaging, delivering up to 1500 mA peak output current at 5.2 V with input as low as 2.65 V. It operates at 3.5 MHz, achieves 93% efficiency, maintains ±2% DC output voltage accuracy, and supports true load disconnect during shutdown - ideal for Li-ion–powered portable devices requiring compact, high-efficiency boost regulation.
For engineers reviewing the TPS612592YFFR datasheet, TPS612592YFFR pinout, TPS612592YFFR application, or TPS612592YFFR equivalent, key selection criteria include its 5.2-V fixed output, 2.65–4.8-V input range, 21-µA standby quiescent current, thermal shutdown protection, and compatibility with ultra-small external components (1-µH inductor, 10-µF output capacitor) enabling <25 mm² total solution size.
Technical Context
The TPS612592YFFR uses valley-current-mode control with quasi-constant on-time PWM for stable regulation across line and load variations. Its integrated dual MOSFETs feature 170-mΩ high-side and 100-mΩ low-side rDS(on), enabling efficient operation down to 2.65 V input while supporting pulsed 1500-mA loads at 5.2 V output.
It implements three distinct operating modes: active boost (EN = high), standby pre-bias (EN = low, BP = high, 21-µA IQ, ~150-mA current-limited output), and true shutdown (EN = low, BP = low, <1-µA ISD). Mode selection is hardware-controlled via dedicated EN and BP pins - no external logic or sequencing required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.2 V ±2% DC accuracy over temperature and load ensures stable USB-compliant power delivery. |
| Input Voltage Range | 2.65 V to 4.8 V - supports full discharge of single-cell Li-ion batteries without brownout. |
| Peak Output Current | 1500 mA at VOUT = 5.2 V, VIN ≥ 3.3 V - enables driving high-pulse-load peripherals like flash LEDs or audio amplifiers. |
| Switching Frequency | 3.5 MHz - allows use of tiny 1-µH inductors and minimizes EMI in space-constrained layouts. |
| Quiescent Current | 21 µA in standby mode - extends battery life during system sleep without sacrificing fast wake-up capability. |
| Efficiency | 93% at 3.5-MHz operation - maximizes energy transfer from low-voltage battery sources. |
| Shutdown Current | <1 µA typical - eliminates parasitic drain during long-term storage or deep-sleep states. |
Pinout & Package
TPS612592YFFR uses a 9-pin DSBGA (NanoFree™) package measuring 1.206 mm × 1.306 mm with 0.4-mm pitch. The die-side ball layout follows standard CSP footprint conventions and requires microvia-in-pad or solder-mask-defined pad design for reliable assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| BP (C3) | Bypass/Mode Select | Hardware-selectable standby mode: BP = high → output pre-biased at VIN with 150-mA limit and 21-µA IQ; BP = low → true shutdown. |
| EN (B3) | Enable Input | Active-high digital control: EN = high → normal boost operation; EN = low → enters mode defined by BP state. |
| GND (C1, C2) | Ground Reference | Dual ground balls minimize impedance and improve thermal dissipation and noise immunity. |
| SW (B1, B2) | Power Switch Node | Internal high- and low-side MOSFET connection point - requires low-inductance routing to external inductor. |
| VIN (A3) | Input Power Supply | Accepts 2.65–4.8 V; connects directly to battery or intermediate rail - bypassed with 4.7-µF ceramic capacitor. |
| VOUT (A1, A2) | Regulated Output | Delivers fixed 5.2 V; routed to load with low-ESR 10-µF ceramic capacitor placed adjacent to VOUT and GND balls. |
Key Features
| Feature | Design Value |
|---|---|
| Light-load PFM mode | Maintains high efficiency at sub-1-mA loads by reducing switching frequency - critical for always-on sensor nodes. |
| Selectable standby vs shutdown | Hardware-configurable BP pin enables either ultra-low-IQ standby (21 µA) or zero-load-discharge shutdown (<1 µA). |
| Synchronous rectification | Integrated NMOS rectifier eliminates external Schottky loss - improves efficiency and reduces thermal stress. |
| Thermal & overload protection | Automatic shutdown at 140°C junction temperature with 20°C hysteresis prevents damage during sustained overload. |
| Total solution size <25 mm² | Requires only one 1-µH inductor and two small MLCCs - enables integration into ultra-thin mobile PCBs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS61258YFFR | Fixed 4.5-V output; higher peak current (1500 mA) but lower VOUT; same package and pinout. | Targeted at 4.5-V systems (e.g., legacy USB ports, specific APA loads); not suitable where 5.2-V compliance is required. | Select TPS61258YFFR only when output voltage must be 4.5 V and load demands exceed 800 mA continuously. |
| TPS61291DRCR | Lower IQ (1.2 µA shutdown, 15 µA PFM); 5.0-V output; 2.5–5.5-V input; 12-pin WSON package. | Larger footprint (2.5 × 2.5 mm), higher cost, but superior light-load efficiency and wider input range. | Choose TPS61291DRCR for ultra-low-power IoT sensors needing sub-µA shutdown and extended battery shelf life. |
Compared with TPS61258YFFR and TPS61291DRCR, the TPS612592YFFR uniquely balances 5.2-V output compliance, 1500-mA pulse capability, 21-µA standby IQ, and 1.2-mm × 1.3-mm footprint - making it optimal for space-constrained, battery-powered consumer electronics requiring precise USB-adjacent voltage rails.

FAQ
What is the fixed output voltage of the TPS612592YFFR?
The TPS612592YFFR provides a factory-trimmed fixed output voltage of 5.2 V with ±2% total DC accuracy across temperature, line, and load conditions. This specification is verified per the datasheet's Electrical Characteristics table under "Regulated DC output voltage" for TPS612592, with typical values of 5.2 V and min/max bounds of 5.1 V and 5.3 V at no load and 2.7–4.8-V input.
Does the TPS612592YFFR support true load disconnect during shutdown?
Yes, the TPS612592YFFR supports true load disconnect when configured in shutdown mode: set EN = low and BP = low. In this state, the internal switches fully isolate VOUT from VIN, and shutdown current drops to less than 1 µA typical. This prevents battery drain and backfeed - confirmed in the datasheet's "Standby mode output ripple voltage" and "Shutdown current" specifications.
What is the minimum input voltage required for the TPS612592YFFR to deliver full 1500-mA peak output?
The TPS612592YFFR requires a minimum input voltage of 3.3 V to sustain 1500-mA peak output current at 5.2 V. This is explicitly stated in the Device Options table and reinforced in the Electrical Characteristics section under "Regulated DC output voltage" test conditions for TPS612592, where pulsed-load operation (≤20 ms, ≤10% duty cycle) is specified at VIN ≥ 3.3 V.
Can the TPS612592YFFR operate with a 1-µH inductor?
Yes, the TPS612592YFFR is optimized for 0.7–2.9-µH inductors, and a 1-µH value is within the recommended range per Section 7.3 (Recommended Operating Conditions). Typical application circuits (e.g., Figure 10) use 1-µH inductors, and the 3.5-MHz switching frequency ensures stable operation with this value while minimizing size and AC losses.
How does the BP pin function on the TPS612592YFFR?
The BP pin on the TPS612592YFFR controls functional mode when EN = low: BP = high enables standby mode (output pre-biased at VIN with ~150-mA current limit and 21-µA quiescent current); BP = low enables true shutdown (<1-µA ISD). This dual-mode capability is documented in the Pin Functions table and Figure 14 (Functional Modes), and requires external termination - BP must never be left floating.
