Product details
Overview
TPS612562CYFFR from Texas Instruments is a 3.5-MHz synchronous step-up DC-DC converter in 9-pin 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 output accuracy, 93% peak efficiency, 37-µA quiescent current in PFM mode, and pass-through operation when EN is pulled low-enabling compact NFC PA supply and smartphone power rail designs.
For engineers reviewing the TPS612562CYFFR datasheet, TPS612562CYFFR pinout, TPS612562CYFFR application, or TPS612562CYFFR equivalent, key selection criteria include its 5.2-V fixed output, 2.3–5.5-V input range, 3.5-MHz constant-frequency PWM with light-load PFM, thermal shutdown at 140°C, and support for ≤25 mm² total solution size with only three external components.
Technical Context
The TPS612562CYFFR employs valley-current-mode control with adaptive slope compensation, enabling stable regulation across wide VIN/VOUT ratios and fast transient response without external compensation. Its quasi-constant on-time architecture dynamically adjusts switching behavior between PWM (moderate-to-heavy load) and PFM (light load), maintaining high efficiency from 1 mA to 800 mA.
It integrates dual MOSFETs (170-mΩ high-side, 100-mΩ low-side), undervoltage lockout (2.0 V threshold, 100-mV hysteresis), soft-start with pre-charge current limiting (500 mA min.), and thermal regulation that throttles output before shutdown at 140°C. Pass-through mode enables direct VIN-to-VOUT conduction with minimal dropout when EN = low and VIN > UVLO.
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 circuits without external feedback. |
| Input Voltage Range | 2.3 V to 5.5 V - supports single-cell Li-ion batteries down to 2.65 V discharge and accommodates USB 5-V input with headroom. |
| Switching Frequency | 3.5 MHz nominal - enables use of sub-1-µH inductors and small ceramic capacitors, minimizing PCB area and EMI filtering needs. |
| Peak Efficiency | 93% at 3.5 MHz - reduces thermal load in space-constrained portable devices and extends battery runtime under typical loads. |
| Quiescent Current | 37 µA (typ) in PFM mode - minimizes standby power loss in always-on NFC or sensor subsystems. |
| Current Limit | 2150 mA (typ) valley current limit - protects internal FETs during short-circuit or overload while sustaining 800 mA continuous output. |
| Thermal Shutdown | 140°C junction temperature (typ) with 20°C hysteresis - provides robust overtemperature protection without latch-up. |
Pinout & Package
TPS612562CYFFR uses a 9-bump DSBGA (NanoFree™) package measuring 1.206 mm × 1.306 mm, optimized for ultra-compact portable layouts. The package features three ground bumps (C1, C2, C3) for low-inductance return paths and dual-source bonding for SW and VOUT pins to reduce parasitic resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN (B3) | Enable control input | Active-high logic: high = boost mode; 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-impedance return for switch node, output, and IC core - critical for EMI and thermal performance. |
| SW (B1, B2) | Switch node | Drain connection of internal high-side MOSFET and source of low-side MOSFET - connects directly to inductor; high dv/dt node requiring tight layout. |
| VIN (A3) | Input power supply | Accepts 2.3–5.5 V; feeds internal regulators and power switches - requires local 4.7-µF ceramic capacitor placed adjacent to pin. |
| VOUT (A1, A2) | Regulated output | Delivers fixed 5.2 V; dual pads reduce IR drop and improve current sharing - connects to 10-µF output capacitor and load. |
Key Features
| Feature | Design Value |
|---|---|
| Pass-through mode | EN = low enables direct conduction path from VIN to VOUT with <100 mV dropout - eliminates need for external bypass FET in dual-input systems. |
| Light-load PFM | Automatically transitions to pulse-frequency modulation below ~10 mA load - cuts quiescent current to 37 µA without sacrificing regulation. |
| Total solution size | <25 mm² with only three external components (1-µH inductor, 4.7-µF input cap, 10-µF output cap) - ideal for thin smartphones and wearables. |
| Integrated protection | Includes undervoltage lockout (2.0 V), thermal shutdown (140°C), valley current limit (2150 mA), and soft-start - eliminates need for discrete supervision circuitry. |
| NanoFree™ packaging | 1.206 mm × 1.306 mm DSBGA with copper pillar interconnect - enables board-level reliability matching QFN while reducing footprint by >70% vs. 2-mm QFN. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-up converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS612564CYFFR | Fixed 5.4 V output; otherwise identical electrical specs and pinout. | Used where higher output voltage is required for legacy flash LEDs or specific PMIC input rails. | Select when system load requires >5.2 V nominal - no layout change needed, but verify downstream voltage tolerance. |
| TPS61252YFFR | Adjustable output (via external resistor divider); 5.5-V max output; 2.5–5.5-V input; 2-MHz switching. | Suitable for multi-rail systems needing programmable voltage or tighter ripple control at lower frequency. | Choose when flexibility in output voltage or reduced EMI sensitivity outweighs fixed-output simplicity and 3.5-MHz size advantage. |
Compared with TPS612562CYFFR, TPS612564CYFFR offers +0.2 V output for margin-sensitive loads but identical footprint and efficiency; TPS61252YFFR trades fixed-voltage simplicity for adjustability and lower switching frequency, increasing solution size and reducing peak efficiency by ~2%.

FAQ
What is the exact output voltage tolerance of the TPS612562CYFFR?
The TPS612562CYFFR delivers a fixed 5.2 V output with ±2% total DC voltage accuracy over temperature, line, and load conditions - verified per TI's SLVSDQ1A datasheet Section 7.5. This specification ensures reliable operation of NFC power amplifiers and flash LED drivers without external trimming or feedback adjustment.
Does the TPS612562CYFFR support input voltages higher than its output voltage?
Yes, the TPS612562CYFFR supports VIN ≥ VOUT operation. When EN is pulled low, it enters forced pass-through mode - allowing VOUT to follow VIN minus small drops across the inductor DCR and high-side FET rDS(on). This feature eliminates the need for external bypass circuitry in dual-input power systems.
What is the minimum recommended output capacitance for stable operation of the TPS612562CYFFR?
The TPS612562CYFFR requires a minimum 10-µF X5R/X7R ceramic output capacitor (e.g., GRM188R60J106ME84) placed directly at the VOUT and GND pins. This value ensures loop stability, limits output ripple to <50 mVpk under 800-mA load, and compensates for MLCC DC bias effects - as confirmed in TI's Application Report SLVSDQ1A Section 10.2.2.2.
How does the TPS612562CYFFR manage thermal performance in compact layouts?
The TPS612562CYFFR incorporates thermal regulation that begins throttling output current at ~110°C junction temperature, followed by hard thermal shutdown at 140°C (typ). Its 9-bump DSBGA package achieves θJA = 108.3°C/W and θJB = 18°C/W - enabling reliable 800-mA operation in ≤25 mm² layouts when using standard 2-layer PCBs with thermal vias to inner ground planes.
Can the TPS612562CYFFR be used with inductors smaller than 1 µH?
Yes - the TPS612562CYFFR is characterized for inductance values from 0.7 µH to 2.9 µH. A 0.7-µH inductor (e.g., LQM21PN1R5MC0) reduces solution height and improves transient response, though it increases peak switch current and may require careful saturation current rating verification per Equation 4 in SLVSDQ1A Section 10.2.2.1.
