Product details
Overview
TPS612562CYFFT from Texas Instruments is a 3.5-MHz synchronous step-up DC-DC converter in NanoFree™ DSBGA packaging, delivering fixed 5.2 V output at up to 800 mA from input voltages as low as 2.3 V. It features ±2% DC voltage accuracy, 37-µA quiescent current in PFM mode, and pass-through operation when EN is pulled low-enabling efficient NFC PA supply and smartphone battery rail boosting.
For engineers reviewing the TPS612562CYFFT datasheet, TPS612562CYFFT pinout, TPS612562CYFFT application, or TPS612562CYFFT equivalent, key selection criteria include its 9-pin DSBGA (1.206 mm × 1.306 mm) footprint, 5.2-V regulated output with 500-mA pass-through current limit, 93% peak efficiency at 3.5 MHz, thermal shutdown at 140°C, and compatibility with 0.7–2.9 µH inductors and 10–50 µF ceramic output capacitors.
Technical Context
The TPS612562CYFFT employs valley-current-mode control with adaptive slope compensation, enabling stable regulation across wide VIN/VOUT ratios (2.3 V–5.5 V input, fixed 5.2 V output) and fast transient response without external compensation. Its quasi-constant on-time PWM architecture operates at 3.5 MHz nominal frequency, transitioning seamlessly into PFM mode below ~10 mA load to maintain high light-load efficiency.
Functional modes include boost regulation, forced pass-through (EN = low), pre-charge soft-start with 500-mA current limiting, undervoltage lockout (2.0 V threshold, 100 mV hysteresis), and thermal regulation that reduces output current above 110°C before full shutdown at 140°C. The integrated high-side PMOS and low-side NMOS switches feature 170 mΩ and 100 mΩ typical RDS(on), respectively.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.2 V ±2% DC accuracy-ensures stable bias for NFC power amplifiers and USB charging ports without external feedback. |
| Switching Frequency | 3.5 MHz nominal-enables use of sub-1-µH inductors and compact 0402/0603 ceramic capacitors for <25 mm² total solution size. |
| Max Output Current | 800 mA in boost mode-supports high-pulse loads in mono/stereo APA and smartphone RF front-ends. |
| Quiescent Current | 37 µA typical in PFM mode-extends battery life in standby and low-power sensing states. |
| Input Voltage Range | 2.3 V to 5.5 V-fully supports single-cell Li-ion batteries across full discharge curve (2.65 V–4.85 V). |
| Pass-Through Current Limit | 500 mA minimum-allows direct battery-to-load conduction with minimal dropout during EN-low operation. |
| Efficiency | 93% peak at 3.5 MHz-minimizes thermal rise in space-constrained mobile PCBs. |
Pinout & Package
TPS612562CYFFT uses a 9-bump DSBGA (NanoFree™) package measuring 1.206 mm × 1.306 mm with 0.4-mm pitch. Thermal performance is optimized via bottom-side GND bumps (C1, C2, C3) and low θJA of 108.3°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN (B3) | Enable control input | High = boost regulation; Low = pass-through mode; must not float-requires pull-up or active drive. |
| GND (C1, C2, C3) | Power ground | Three dedicated ground terminals provide low-inductance return path and thermal dissipation. |
| SW (B1, B2) | Switch node | Drain connection of internal high-side PMOS and low-side NMOS-connects to inductor and requires tight layout for EMI control. |
| VIN (A3) | Input power supply | Accepts 2.3–5.5 V; feeds internal regulators and power switches-requires local 4.7-µF ceramic decoupling. |
| VOUT (A1, A2) | Regulated output | Delivers fixed 5.2 V; dual pins reduce IR drop and improve current sharing for 800-mA loads. |
Key Features
| Feature | Design Value |
|---|---|
| Light-load PFM mode | Reduces IQ to 37 µA while maintaining regulation-critical for battery runtime in always-on NFC and sensor applications. |
| Pass-through mode | EN-low state bypasses switching, letting VOUT follow VIN minus inductor DCR + HS-FET RDS(on)-eliminates conversion loss during high-input conditions. |
| Nine-pin NanoFree™ CSP | 1.206 mm × 1.306 mm footprint with 0.4-mm pitch-enables ultra-compact layouts in thin smartphones and wearables. |
| Thermal regulation | Active current reduction above 110°C die temperature-prevents thermal runaway during sustained 800-mA loads without system-level intervention. |
| Only three external components | Requires just one inductor, one input capacitor, and one output capacitor-reduces BOM count, assembly cost, and board area. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-up converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS61256CYFFT | Fixed 5.0 V output; identical package, pinout, and electrical specs except VOUT setpoint and corresponding load capability down to 3.3 V input. | Suitable where 5.0 V (not 5.2 V) is required for USB 2.0 peripherals or legacy audio codecs. | Select TPS61256CYFFT when system-level tolerance allows 5.0 V instead of 5.2 V-no layout change needed. |
| TPS612564CYFFT | Fixed 5.4 V output; same DSBGA-9 package and functional behavior, but higher VOUT enables tighter margin for 5.25-V USB PD sink rails. | Preferred for USB Power Delivery sink applications requiring >5.2 V headroom or future-proofing against voltage droop in long cables. | Choose TPS612564CYFFT only if 5.4 V is explicitly required-verify downstream device overvoltage tolerance before substitution. |
Compared with TPS61256CYFFT and TPS612564CYFFT, the TPS612562CYFFT provides the optimal 5.2-V setpoint for NFC PA bias and modern USB charging ports, balancing headroom against overvoltage risk while retaining identical thermal, layout, and control characteristics.

FAQ
What is the exact output voltage tolerance of the TPS612562CYFFT?
The TPS612562CYFFT delivers a fixed 5.2 V output with ±2% total DC voltage accuracy over temperature, line, and load conditions. This specification is verified per TI's SLVSDQ1A datasheet Section 7.5, where measured values fall within 5.12 V to 5.28 V at 25°C with 2.3–4.85 V input and zero load current-ensuring reliable biasing for NFC PAs and USB charging circuits without external trimming.
Does the TPS612562CYFFT require external compensation components?
No, the TPS612562CYFFT integrates full internal compensation optimized for 1-µH inductors and 10-µF output capacitors. Its valley-current-mode architecture with adaptive slope compensation eliminates the need for external RC networks, reducing design complexity and PCB area-confirmed in Section 9.1 and Figure 9 of the SLVSDQ1A datasheet.
Can the TPS612562CYFFT operate with input voltages above its output voltage?
Yes, the TPS612562CYFFT supports VIN ≥ VOUT operation via its forced pass-through mode: when EN is pulled low and VIN exceeds UVLO (2.0 V), the output follows VIN minus voltage drops across the inductor DCR and high-side FET RDS(on). This feature is explicitly documented in Sections 3, 9.3.2, and 9.4.2 of the datasheet.
What is the maximum continuous output current capability of the TPS612562CYFFT in boost mode?
The TPS612562CYFFT supports up to 800 mA of continuous output current in boost mode when powered from a 3.3 V input or higher, as specified in the Device Options table (Section 5) and validated in Figure 2 (DC Output Voltage vs Output Current). At lower inputs (e.g., 2.65 V), output current is limited by thermal and switch current limits to maintain regulation.
How does thermal regulation function in the TPS612562CYFFT during sustained high-load operation?
The TPS612562CYFFT implements active thermal regulation that begins reducing output current when die temperature reaches ~110°C, preventing thermal runaway before full shutdown at 140°C. This behavior is detailed in Section 9.3.5 and ensures safe operation under 800-mA loads in confined spaces-without requiring external thermal sensors or firmware intervention.
