Product details
Overview
TPS61253YFFR from Texas Instruments is a synchronous step-up DC-DC converter in 9-pin NanoFree™ DSBGA packaging, delivering regulated 5.0 V output at up to 1000 mA continuous or 1500 mA peak load current from input voltages as low as 2.65 V. It operates at 3.5 MHz with 93% peak efficiency and ±2% DC output voltage accuracy, targeting compact battery-powered systems such as smartphones and USB charging ports.
For engineers reviewing the TPS61253YFFR datasheet, TPS61253YFFR pinout, TPS61253YFFR application, or TPS61253YFFR equivalent, key selection criteria include its 21-µA standby quiescent current, VIN ≥ VOUT capability, true load disconnect during shutdown, and minimal external component count (only three surface-mount parts required) for sub-25 mm² total solution size.
Technical Context
The TPS61253YFFR employs quasi-constant on-time valley current mode control in PWM operation and transitions to PFM at light loads to maintain high efficiency across 0.1–1000 mA output range. Its dual-mode operation-boost (BST), standby (SM), and true shutdown (SD)-is controlled via EN and BP pins, enabling dynamic power management in portable devices.
Internally integrated high-side (170 mΩ) and low-side (100 mΩ) MOSFETs support synchronous rectification, while built-in thermal shutdown (140°C), overcurrent protection (3.62 A valley limit), and under-voltage lockout (2.1 V threshold) ensure robust operation without external supervision circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0 V ±2% DC accuracy ensures stable USB 5V rail generation without external feedback resistors. |
| Input Voltage Range | 2.65 V to 4.85 V supports single-cell Li-ion batteries down to near depletion, enabling extended runtime. |
| Max Continuous Output | 1000 mA at VOUT = 5.0 V, VIN ≥ 3.3 V sustains full-power USB peripheral operation under typical battery conditions. |
| Peak Output Current | 1500 mA pulsed (≤20 ms, ≤10% duty) handles transient loads like camera flash or audio amplifier peaks. |
| Switching Frequency | 3.5 MHz enables use of ultra-small 1 µH inductors and minimizes EMI filtering requirements. |
| Quiescent Current | 21 µA in standby mode extends battery life during system sleep states without compromising wake-up responsiveness. |
| Shutdown Current | <5 µA ensures negligible battery drain when fully disabled, critical for always-on portable devices. |
Pinout & Package
TPS61253YFFR uses a 1.206 mm × 1.306 mm 9-pin NanoFree™ DSBGA (YFF) package with bottom-side solder balls. Thermal resistance RθJA is 108.3°C/W, requiring PCB copper pour for thermal management in high-load applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| BP (C3) | Mode select bias pin | When EN = Low, BP = High enables standby mode (21 µA IQ, VOUT ≈ VIN, ~150 mA pre-bias capability); BP = Low forces true shutdown with load disconnect. |
| EN (B3) | Enable control input | Active-high logic: pull ≥1.0 V to enable boost operation; tie to GND to disable. Must not float. |
| GND (C1, C2) | Power ground | Dual ground connections reduce impedance and improve noise immunity in high-frequency switching paths. |
| SW (B1, B2) | Internal switch node | Connects to external inductor; carries high di/dt switching current; requires short, low-inductance PCB trace. |
| VIN (A3) | Input power supply | Accepts 2.65–4.85 V; must be decoupled with ≥3.5 µF ceramic capacitor close to pin. |
| VOUT (A1, A2) | Regulated output | Delivers fixed 5.0 V; requires ≥3.5 µF output capacitance; dual pins reduce IR drop under 1000 mA load. |
Key Features
| Feature | Design Value |
|---|---|
| Light-load PFM mode | Maintains >85% efficiency down to 0.1 mA output by reducing switching frequency, extending battery life in idle states. |
| Selectable standby mode | Enables pre-biased output at input voltage level with only 21 µA quiescent current-ideal for powering audio amplifiers during low-power listening. |
| True load disconnect | Physically isolates VOUT from VIN during shutdown (EN = Low, BP = Low), preventing backfeed and leakage into powered-down subsystems. |
| Integrated MOSFETs | Eliminates need for external power switches; 170 mΩ high-side and 100 mΩ low-side RDS(on) minimize conduction losses at full load. |
| Total solution size <25 mm² | Achieved with only one 1 µH inductor and two small ceramic capacitors-enables integration into space-constrained mobile PCBs. |
Applications
| Cell Phones & Smartphones | USB Charging Ports (5 V) |
|---|---|
Use Scenario: Powering display backlight, RF transceivers, and sensors from a single discharged Li-ion cell (2.7–4.2 V).

IC Role / Device Role / Timing Role: Ultra-compact DC-DC solution with <25 mm² footprint and 21 µA standby IQ, enabling multi-day operation on coin-cell batteries. Use Value: Reduces total BOM count to just three passive components-inductor, input cap, output cap-lowering assembly cost and test complexity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS61258YFFR | Same 4.5 V output, but supports 1500 mA peak at VIN ≥ 3.3 V; higher valley current limit (3.62 A vs 3.62 A identical) and same 3.5 MHz frequency. | Targeted at 4.5 V systems (e.g., older USB specs or specific APA rails), not 5.0 V USB-compliant outputs. | Select TPS61258YFFR only when fixed 4.5 V output is required; otherwise TPS61253YFFR is optimal for standard 5 V USB power delivery. |
| TPS61099YFFR | Lower 3.3 V output, 2.5 V minimum input, 200 mA max output, and 1.2 MHz switching frequency-smaller solution but lower performance envelope. | Suitable for ultra-low-power MCU rails or sensor biasing, not for 5 V USB or high-current audio loads. | Choose TPS61099YFFR only for sub-200 mA, 3.3 V applications where minimal IQ (300 nA) outweighs output voltage and current requirements. |
Compared with TPS61258YFFR and TPS61099YFFR, the TPS61253YFFR uniquely delivers 5.0 V at 1000 mA continuous from a 2.65 V input in a 9-ball CSP, making it the only direct fit for space-constrained, battery-powered 5 V USB port and smartphone system rail applications.

FAQ
What is the minimum input voltage required for TPS61253YFFR to regulate 5.0 V output?
The TPS61253YFFR requires a minimum input voltage of 2.65 V to deliver 1000 mA continuous output at 5.0 V. Below this threshold, regulation degrades; the device remains functional down to 2.3 V but cannot sustain full load. This 2.65 V specification is validated across –40°C to 85°C ambient temperature and accounts for internal voltage drops and efficiency loss.
Does TPS61253YFFR support true load disconnect during shutdown?
Yes, TPS61253YFFR provides true load disconnect when EN = Low and BP = Low. In this configuration, both internal MOSFETs are fully off, breaking the conductive path between VIN and VOUT. Input-to-output leakage is limited to <3.5 µA, ensuring no backfeed into powered-down circuits-a critical feature for system-level power gating.
What is the recommended inductor value for TPS61253YFFR in a typical 5 V application?
The datasheet specifies a nominal inductor value of 1.0 µH (range 0.7–2.9 µH) for TPS61253YFFR. A 1.0 µH, 2.5 A saturation current shielded ceramic inductor (e.g., Coilcraft XAL5030-102MEB) is recommended to balance size, efficiency (>90% at 500 mA), and transient response while avoiding saturation under 1500 mA peak loads.
How does TPS61253YFFR manage efficiency at light loads?
TPS61253YFFR automatically enters pulse frequency modulation (PFM) mode below ~10 mA output current, reducing switching frequency and quiescent current to 37 µA (typ). This preserves >85% efficiency at 1 mA load-critical for maintaining battery life in standby states without requiring external mode-control circuitry.
Can TPS61253YFFR operate with input voltage higher than output voltage?
Yes, TPS61253YFFR supports VIN ≥ VOUT operation. When VIN ≥ 5.0 V, the device enters pass-through mode: the high-side MOSFET remains on, the low-side is off, and VOUT tracks VIN minus the RDS(on) drop (≤170 mΩ × ILOAD). This avoids unnecessary switching loss and improves efficiency in partially charged battery scenarios.
