Product details
Overview
TPS612532AYFFR from Texas Instruments is a 3.8MHz synchronous boost converter in 1.2mm × 1.3mm DSBGA (YFF) package, delivering fixed 5V output with ±2% accuracy, 4A switching valley current limit, and 42µA quiescent current. It supports pass-through mode, hiccup-mode short protection, and load disconnection during shutdown-optimized for Li-ion battery–powered USB charging ports and NFC power amplifiers.
For engineers reviewing the TPS612532AYFFR datasheet, TPS612532AYFFR pinout, TPS612532AYFFR application, or TPS612532AYFFR equivalent, key selection criteria include its 5V fixed output, 4A valley current limit, 1.2mm × 1.3mm WCSP footprint, output discharge function, and support for Auto PFM/Forced PWM/Ultrasonic operating modes.
Technical Context
The TPS612532AYFFR implements valley-current-mode control with quasi-constant on-time PWM at 3.8MHz under medium-to-heavy loads, enabling stable regulation with small 0.33–1.3µH inductors and ceramic capacitors. Its integrated 35mΩ LS-FET and 60mΩ HS-FET minimize conduction loss while supporting continuous 1500mA output at VOUT = 5V and VIN ≥ 3V.
Three configurable operating modes-Auto PFM (light-load efficiency), Forced PWM (fixed 3.8MHz frequency across load range), and Ultrasonic (switching >25kHz to eliminate audible noise)-are selected via the MODE pin. Pass-through mode activates when VIN exceeds VOUT + 0.1V, bypassing switching to reduce losses.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltage | Fixed 5V with ±2% accuracy over temperature and line/load conditions |
| Switching frequency | 3.8MHz nominal in PWM mode; >25kHz minimum in Ultrasonic mode |
| Valley current limit | 4A typical-sets maximum inductor current during boost operation |
| Quiescent current | 42µA from VIN in no-switching state-enables ultra-low standby power |
| Input voltage range | 2.3V to 5.5V-supports full Li-ion battery discharge curve (3.0–4.2V nominal) |
| Soft-start time | 600µs-limits inrush current during power-up to protect input source and output cap |
| Output discharge | Integrated RDIS = 350Ω-actively discharges VOUT after shutdown for system safety |
Pinout & Package
TPS612532AYFFR uses a 9-pin DSBGA (YFF) package measuring 1.2mm × 1.3mm with 0.4mm pitch. The package is bottom-side soldered with exposed die attach pad (no thermal pad connection required).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN (B3) | Enable input | Active-high logic: >1.2V enables device; internal 930kΩ pull-down ensures default shutdown |
| GND (C1, C2) | Power ground | Dual ground pins minimize PCB ground impedance and improve thermal dissipation |
| MODE (C3) | Operating mode select | Low = Auto PFM; High = Forced PWM; Floating = Ultrasonic mode (0.75–0.85V internal bias) |
| SW (B1, B2) | Switch node | Shared drain-source connection of internal HS/LS FETs-requires low-inductance layout |
| VIN (A3) | Input supply | Accepts 2.3–5.5V; connects to input capacitor and battery/analog rail |
| VOUT (A1, A2) | Regulated output | Delivers fixed 5V; dual pins reduce IR drop and improve current handling |
Key Features
| Feature | Design Value |
|---|---|
| Output discharge function | Integrated 350Ω discharge path actively pulls VOUT to GND after EN deactivation-eliminates residual voltage in portable systems |
| Pass-through mode | Automatic transition to low-loss linear conduction when VIN > VOUT + 0.1V-extends battery runtime in high-VIN conditions |
| Hiccup-mode short protection | 1ms on / 20ms off cycling during output short-limits average power dissipation and enables self-recovery without external intervention |
| Load disconnection at shutdown | Internal switch isolates VOUT from VIN during EN = low-prevents battery drain in powered-off state (ISD ≤ 1.3µA) |
| Thermal shutdown | Triggers at TJ ≥ 150°C with 20°C hysteresis-protects silicon integrity during sustained overload or poor heatsinking |

Equivalent & Alternatives
The following parts are listed as comparable options for similar boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS61253AYFFR | No output discharge resistor; identical 5V output, 4A current limit, and pinout | Lacks active VOUT discharge-unsuitable where residual voltage violates system safety requirements | Select TPS612532AYFFR when output discharge is mandatory; choose TPS61253AYFFR for cost-sensitive designs without discharge need |
| TPS61253FYFFR | 4.5A valley current limit; supports 1.2V/1.8V I/O logic; same 5V output and YFF package | Better suited for low-voltage host MCU interfaces; higher current headroom for peak loads | Choose TPS61253FYFFR if interfacing with 1.2V GPIO or requiring >4A surge capability; otherwise TPS612532AYFFR offers optimal balance |
Compared with TPS61253AYFFR, TPS612532AYFFR adds verified output discharge functionality without altering footprint or control interface; versus TPS61253FYFFR, it trades 0.5A current headroom and dual-voltage I/O support for lower cost and simpler system-level validation.

FAQ
What is the output voltage accuracy of the TPS612532AYFFR?
The TPS612532AYFFR provides a fixed 5V output with ±2% accuracy across operating temperature (–40°C to 125°C), input voltage (2.3V to 5.5V), and load current (0–1500mA). This tolerance is guaranteed by internal precision voltage reference and feedback network trimming, ensuring reliable 5V rail generation without external resistor networks or calibration.
Does the TPS612532AYFFR support automatic pass-through operation?
Yes, the TPS612532AYFFR automatically enters pass-through mode when VIN exceeds VOUT + 0.1V and VOUT remains above nominal regulation. In this state, the high-side FET fully turns on and the low-side FET turns off, allowing near-lossless conduction with only inductor DCR and RDS(on) drop-reducing quiescent power and extending battery life in high-input scenarios.
How does the output discharge function work in the TPS612532AYFFR?
The TPS612532AYFFR integrates a dedicated 350Ω NMOS discharge path between VOUT and GND, activated immediately upon EN deassertion. This rapidly drains stored charge from output capacitors-reducing VOUT to <0.8V within 10ms for a 10µF load-ensuring safe system reset and preventing unintended wake-up or latch-up in downstream circuitry.
What protection features are built into the TPS612532AYFFR?
The TPS612532AYFFR includes hiccup-mode short-circuit protection (1ms on / 20ms off cycling), thermal shutdown (150°C trip with 20°C hysteresis), undervoltage lockout (2.3V rising threshold), load disconnection during shutdown (<1.3µA ISD), and valley-current limiting (4A typical). These operate autonomously without external components or host intervention.
Can the TPS612532AYFFR operate with a 2.3V input from a deeply discharged Li-ion cell?
Yes, the TPS612532AYFFR starts up reliably at VIN = 2.3V (rising UVLO threshold) and delivers 1500mA continuously at VOUT = 5V when VIN ≥ 3V. At 2.3V input, it sustains regulated 5V output at reduced load-enabling full utilization of Li-ion cells down to safe termination voltage without premature system shutdown.
