Product details
Overview
TPS61241YFFR from Texas Instruments is a synchronous step-up DC-DC converter optimized for single-cell Li-ion/Li-polymer or three-cell alkaline/NiMH battery-powered portable devices. It delivers a fixed 5.0 V ±2% output with up to 300 mA load current at VIN ≥ 3.2 V, features 3.5-MHz quasi-constant on-time valley current mode control, 30-μA quiescent current in power-save mode, and automatic PFM/PWM transition.
For engineers reviewing the TPS61241YFFR datasheet, TPS61241YFFR pinout, TPS61241YFFR application, or TPS61241YFFR equivalent, key selection considerations include input valley current limit (600 mA), load disconnect during shutdown, 250-μs typical start-up time, low-ripple power-save mode, and compatibility with 1.0–2.2 μH inductors and ceramic capacitors for <13 mm² total solution size.
Technical Context
The TPS61241YFFR implements a quasi-constant on-time valley current mode control architecture that enables fast line and load transient response without external compensation. Its valley current sensing occurs during switch off-time via the synchronous rectifier's voltage drop, enabling precise current limiting and stable operation across wide input (2.3–5.5 V) and output (5.0 V) conditions.
It integrates undervoltage lockout (2.1 V rising, 2.0 V falling), input overvoltage protection (6.0 V trip), thermal shutdown (140 °C), and internal softstart (250 μs to 5 V). During shutdown, it presents high impedance at VOUT and fully disconnects the load from the battery-critical for USB-OTG and HDMI port power sharing.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS61240YFFR | 500 mA input valley current limit vs. 600 mA; same 5.0 V output, package, and pinout. | Rated for ≤250 mA loading down to 3.2 V input-lower max output capability under low-VIN conditions. | Select TPS61240YFFR only if system peak load stays below 250 mA at battery voltages ≤3.2 V. |
| TPS610987DSER | Lower IQ (200 nA shutdown, 400 nA operating), but fixed 3.3 V output and 200 mA max load; 1.2-mm × 1.6-mm WSON. | Not suitable for 5 V USB/HDMI applications; targets ultra-low-power always-on rails (RTC, sensors). | Choose TPS610987DSER only for sub-μA standby systems requiring 3.3 V-not as a functional replacement for 5 V TPS61241YFFR. |

FAQ
What is the fixed output voltage of the TPS61241YFFR and how is it set?
The TPS61241YFFR delivers a fixed 5.0 V ±2% output voltage. This is achieved using an internal resistor divider network tied to the FB pin, which is internally referenced to a precision bandgap. The FB pin must be directly connected to VOUT-no external resistors are required or supported. This simplifies layout and eliminates calibration drift, ensuring consistent USB-OTG and HDMI compliance across temperature and unit-to-unit variation. The TPS61241YFFR does not support adjustable output configurations.
Does the TPS61241YFFR support load disconnect during shutdown, and why is this important?
Yes, the TPS61241YFFR presents high impedance at the VOUT pin and fully disconnects the load from the battery when EN is pulled low. This prevents reverse current flow and eliminates battery drain during system sleep or off-states. It is essential for USB-OTG dual-role ports where the device may act as either host or peripheral-the 5 V rail must be isolated when not actively supplying power to avoid back-driving or violating USB specification voltage limits. The TPS61241YFFR achieves this without external MOSFETs or control logic.
What is the input valley current limit of the TPS61241YFFR, and how does it differ from the TPS61240YFFR?
TPS61241YFFR has a confirmed input valley current limit of 600 mA, while TPS61240YFFR is rated at 500 mA. This 20% higher limit allows TPS61241YFFR to sustain up to 300 mA output current at input voltages as low as 3.2 V-critical for maintaining USB-OTG functionality late in battery discharge. Both share identical pinout, package, and 5.0 V output, making them drop-in replacements in most designs, though TPS61241YFFR offers superior low-VIN headroom. The difference is explicitly documented in TI's Device Options table.
Can the TPS61241YFFR operate with ceramic capacitors only, and what are the recommended values?
Yes, the TPS61241YFFR is designed for all-ceramic capacitor operation. TI specifies a minimum 2.2 μF X5R/X7R ceramic input capacitor (CIN) placed close to VIN/GND, and a 4.7 μF ceramic output capacitor (COUT) at VOUT/GND-both in 0402 case size. These values ensure stable regulation, low output ripple (<20 mVpp in PWM mode), and robust transient response. Larger capacitance improves hold-up time but is not required. MLCCs are mandatory; electrolytic or tantalum capacitors are not recommended due to ESR and frequency limitations.
What protection features are integrated into the TPS61241YFFR?
The TPS61241YFFR integrates undervoltage lockout (UVLO: 2.1 V rising, 2.0 V falling), input overvoltage protection (OVLO: 6.0 V trip), thermal shutdown (140 °C with 20 °C hysteresis), and current overload protection via valley current limiting. All functions operate autonomously without external components. UVLO prevents deep battery discharge; OVLO safeguards against accidental 5 V USB cable misconnection; thermal shutdown protects against PCB overheating; and current limiting ensures safe operation during short circuits or excessive loads. These protections are validated across –40°C to 85°C ambient operation.
