Product details
Overview
TPS61240YFFR 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 200 mA continuous load current, operates from 2.3 V to 5.5 V input, achieves >90% efficiency at nominal conditions, and features automatic PFM/PWM mode transition for light-load efficiency.
For engineers reviewing the TPS61240YFFR datasheet, TPS61240YFFR pinout, TPS61240YFFR application, or TPS61240YFFR equivalent, key selection considerations include its 3.5-MHz switching frequency, 30-μA quiescent current in power-save mode, internal softstart (250-μs typical startup), load disconnect during shutdown, and DSBGA-6 (1.25 mm × 0.86 mm) package for ultra-compact USB-OTG and portable HDMI power rails.
Technical Context
The TPS61240YFFR implements a quasi-constant on-time valley current mode control architecture, enabling fast line and load transient response without external compensation. Its valley current sensing uses the synchronous rectifier's voltage drop to detect overcurrent, triggering frequency foldback under overload.
It integrates undervoltage lockout (2.1 V rising, 2.0 V falling), input overvoltage protection (6.0 V trip), thermal shutdown (140 °C), and an internal 5-V feedback reference. The EN pin enables positive-polarity sequencing, and the FB pin connects directly to VOUT for fixed-output regulation-no external resistors required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0 V ±2% - eliminates need for external feedback resistors; supports USB-OTG host voltage compliance. |
| Input Voltage Range | 2.3 V to 5.5 V - accommodates full discharge curve of one-cell Li-ion (3.0–4.2 V) and three-cell alkaline (3.6–4.5 V). |
| Max Output Current | 200 mA continuous - verified at VIN ≥ 3.2 V; sufficient for HDMI sink power and USB-OTG VBUS sourcing. |
| Switching Frequency | 3.5 MHz typical - enables use of sub-1-μH inductors and 0402 ceramic capacitors for <13 mm² total solution size. |
| Quiescent Current | 30 μA typical in power-save mode - extends battery runtime in standby states of portable media players. |
| Shutdown Current | 1.5 μA - ensures negligible battery drain during system sleep; load disconnect isolates VOUT from VIN. |
| Current Limit | 500 mA input valley current limit - protects internal 290-mΩ high-side and 250-mΩ low-side MOSFETs during overload. |
Pinout & Package
TPS61240YFFR is packaged in a 6-pin DSBGA (YFF) with 1.25 mm × 0.86 mm body size and 0.4-mm pitch. This chip-scale package supports ultra-thin portable designs and requires microvia PCB routing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Input supply rail | Connects to battery or primary DC source; accepts 2.3–5.5 V; decoupled with 2.2-μF ceramic capacitor. |
| EN | Enable control input | Positive-threshold logic (VIH = 1.0 V min); pulls low to disable IC and reduce current to 1.5 μA. |
| VOUT | Regulated output | Delivers fixed 5.0 V; provides up to 200 mA; high-impedance when disabled to allow back-driving by alternate supplies. |
| FB | Feedback sense node | Internally connected to 5-V reference; must be shorted to VOUT for regulation-no external divider needed. |
| GND | Power and signal ground | Common return for VIN, VOUT, and internal circuitry; requires low-inductance connection to minimize noise. |
| L | Inductor switch node | Connects to boost inductor; carries high-frequency AC current; layout critical for EMI and efficiency. |
Key Features
| Feature | Design Value |
|---|---|
| Automatic PFM/PWM mode transition | Eliminates manual mode selection; maintains >90% efficiency from 100 μA to 200 mA load without external control. |
| Load disconnect during shutdown | Breaks electrical path between VIN and VOUT using internal switches-prevents battery drain when system is off. |
| Internal softstart | Ramps VOUT from 5% to 5.0 V in 250 μs; limits inrush current and avoids input voltage sag on weak battery sources. |
| Low-ripple power-save mode | Generates PFM pulses with 0.015 × VOUT ripple amplitude-reduces output filter requirements vs conventional burst mode. |
| Three external component requirement | Only needs one MLCC inductor (1 μH), one input cap (2.2 μF), and one output cap (4.7 μF)-minimizes BOM count and board area. |
Applications
| USB-OTG Host Power | Portable HDMI Sink |
|---|---|
Use Scenario: Mobile phone acting as USB host to power peripherals (keyboard, flash drive) via OTG cable. IC Role / Device Role / Timing Role: Step-up regulator generating stable 5.0 V VBUS from declining Li-ion battery (3.0–4.2 V).

IC Role / Device Role / Timing Role: High-efficiency pre-regulator preceding constant-current LED driver; handles pulsed 300-ms flash loads. Use Value: 3.5-MHz operation minimizes inductor size (1.0 μH, 0805) and avoids audible noise-critical for thin camera modules. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar step-up converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS61241YFFR | 600 mA input valley current limit vs. 500 mA; supports up to 300 mA output at VIN ≥ 3.2 V. | Better suited for higher-current USB-OTG hosts or dual-display HDMI applications. | Select TPS61241YFFR if peak load exceeds 200 mA and board layout allows same DSBGA footprint. |
| MT9700-5.0 | Fixed 5.0 V output; 2.5–5.5 V input; 300 mA max; 2.5 MHz switching; 40 μA IQ; WLCSP-6 package (1.56 mm × 1.56 mm). | Larger package and lower frequency increase solution size but improve thermal margin for sustained 250 mA loads. | Choose MT9700-5.0 when thermal derating is critical and PCB space permits larger WLCSP. |
Compared with TPS61241YFFR and MT9700-5.0, the TPS61240YFFR offers the smallest solution size (<13 mm²) and lowest quiescent current (30 μA), making it optimal for space-constrained, battery-life-sensitive USB-OTG and portable HDMI designs where 200 mA output suffices.

FAQ
What is the output voltage tolerance of the TPS61240YFFR, and how is it maintained?
The TPS61240YFFR provides a fixed 5.0 V output with ±2% DC accuracy over temperature and line/load conditions. This tolerance is maintained by an internal precision voltage reference and feedback amplifier that regulates VOUT via the FB pin-no external resistors are required since the divider is integrated. The device achieves this accuracy across its full 2.3–5.5 V input range and 0–200 mA load range, as confirmed in TI's SLVS806D datasheet Section 7.5.
Does the TPS61240YFFR require external feedback resistors to set its output voltage?
No, the TPS61240YFFR does not require external feedback resistors. Its 5.0 V output is factory-trimmed and internally regulated using a dedicated feedback network connected to the FB pin. The FB pin must be shorted directly to VOUT to close the loop-adding external resistors would disrupt regulation and void the ±2% output accuracy guarantee. This simplifies design and reduces BOM count.
How does the TPS61240YFFR handle load transients, and what is its typical response?
The TPS61240YFFR delivers "Best in Class" load transient response due to its quasi-constant on-time valley current mode control. For a 50–200 mA step change at VIN = 3.6 V, the output voltage deviates by ≤150 mVpk, recovering within microseconds. This performance enables stable operation with fast-switching digital loads like HDMI hot-plug detection circuits without requiring oversized output capacitance.
What protection features are integrated into the TPS61240YFFR?
The TPS61240YFFR integrates undervoltage lockout (2.1 V turn-on, 2.0 V shutdown), input overvoltage protection (6.0 V shutdown), thermal shutdown (140 °C), current overload limiting (500 mA input valley limit), and reverse leakage suppression (<2.5 μA from VOUT to VIN during shutdown). These features eliminate the need for external protection circuitry in portable designs.
Can the TPS61240YFFR be used in applications where the output bus may be driven by another supply?
Yes, the TPS61240YFFR presents high impedance at the VOUT pin during shutdown, allowing the output bus to be safely driven by an alternate supply (e.g., USB host port or external charger) without back-feeding or damage. This capability is explicitly supported by its load disconnect function and is validated in TI's application note for USB-OTG dual-power scenarios.
