Product details
Overview
TPS61240DRVT 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, 90%+ efficiency at nominal conditions, 3.5-MHz switching frequency, and 30-μA quiescent current in power-save mode.
For engineers reviewing the TPS61240DRVT datasheet, TPS61240DRVT pinout, TPS61240DRVT application, or TPS61240DRVT equivalent, this page provides verified technical context, real-world design meaning of key specs, validated pin functions, application-specific implementation insights, and two confirmed alternative parts with functional and selection guidance.
Technical Context
The TPS61240DRVT uses quasi-constant on-time valley current mode control to achieve fast line/load transient response and stable regulation across 2.3 V–5.5 V input. Its internal 5-V reference and fixed feedback divider enable precise output without external resistors.
It integrates high-side (290 mΩ) and low-side (250 mΩ) MOSFETs, automatic PFM/PWM mode transition, undervoltage lockout (2.1 V rising), input overvoltage protection (6.0 V), thermal shutdown (140 °C), and load disconnect during shutdown - all in a 6-pin DSBGA package with 1.25 mm × 0.86 mm footprint.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0 V ±2% - eliminates need for external feedback resistors; supports USB-OTG/HDMI bus power compliance. |
| Input Voltage Range | 2.3 V to 5.5 V - enables operation across 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 - sufficient for USB-OTG host mode (100 mA min) and portable HDMI sink power rails. |
| Switching Frequency | 3.5 MHz typical - allows use of ultra-small 1.0 μH inductor and 0402 ceramic capacitors; reduces solution size to <13 mm². |
| Quiescent Current | 30 μA typical in power-save mode - extends battery life in standby states of always-on portable media players. |
| Efficiency | >90% at nominal load - minimizes thermal rise in space-constrained handheld enclosures; validated at 3.6 VIN/5 VOUT/150 mA. |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Power input | Connects to battery or primary supply; accepts 2.3–5.5 V; requires ≥2.2 μF ceramic capacitor close to pin. |
| EN | Enable control | Active-high logic input; 1.0 V threshold; pulls device into <1.5 μA shutdown when grounded. |
| VOUT | Regulated output | Delivers fixed 5.0 V; presents high impedance during shutdown to allow back-driving by alternate supplies. |
| FB | Feedback sense | Internally connected to 5-V reference; must be shorted directly to VOUT - no external resistor network required. |
| GND | Power/IC ground | Common return for input, output, and internal circuitry; requires low-inductance connection to PCB ground plane. |
| L | Inductor switch node | Connects to boost inductor; carries high di/dt switching current; layout critical for EMI and efficiency. |
Key Features
| Feature | Design Value |
|---|---|
| Automatic PFM/PWM mode transition | Maintains >85% efficiency from 100 μA to 200 mA load - eliminates manual mode selection and simplifies firmware control. |
| Load disconnect during shutdown | Breaks conductive path between VIN and VOUT - prevents battery drain when system is off; no external MOSFET needed. |
| Internal softstart (250 μs) | Controls output ramp rate to limit inrush current - avoids input voltage sag on weak batteries or high-impedance sources. |
| 3.5-MHz fixed-frequency PWM | Enables use of 1.0 μH MLCC inductors - reduces solution height and area vs. lower-frequency alternatives requiring ≥4.7 μH. |
| Thermal + current + UVLO + OVP protection | Single-chip fault coverage - eliminates need for discrete protection ICs in cost-sensitive portable designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-up converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS61241DRVT | Higher 600 mA input valley current limit vs. 500 mA; same 5-V output, package, and pinout. | Supports up to 300 mA output loading down to 3.2 V input - better for higher-current USB-OTG or dual-display HDMI. | Select TPS61241DRVT when peak load exceeds 200 mA or input voltage may drop below 3.2 V under load. |
| MT9700-5.0 | Fixed 5-V output, 3-MHz switching, but 400 mA max output and 45 μA quiescent current - less efficient at light loads. | Requires external feedback resistors; larger solution size due to 2.2 μH inductor requirement. | Choose MT9700-5.0 only if DSBGA package compatibility is not required and BOM cost is prioritized over efficiency. |
Compared with TPS61240DRVT, TPS61241DRVT offers higher current headroom with identical footprint and interface, while MT9700-5.0 trades efficiency and integration for lower unit cost - making TPS61240DRVT optimal for space- and battery-life-critical 200-mA portable applications.

FAQ
What is the output voltage tolerance of the TPS61240DRVT?
The TPS61240DRVT provides a fixed 5.0 V output with ±2% DC accuracy over temperature and line/load conditions. This is guaranteed across the full recommended operating range (2.3 V–5.5 V input, –40°C to 85°C ambient), as specified in Section 7.5 of the SLVS806D datasheet. The internal reference and feedback network ensure no external resistor calibration is needed for TPS61240DRVT.
Does the TPS61240DRVT require external feedback resistors?
No, the TPS61240DRVT does not require external feedback resistors. Its output voltage is factory-trimmed to 5.0 V using an internal resistor divider connected to the FB pin. Per the datasheet Functional Description, the FB pin must be shorted directly to VOUT - adding external resistors will disrupt regulation and invalidate the ±2% accuracy guarantee for TPS61240DRVT.
What is the minimum input voltage before the TPS61240DRVT shuts down?
TPS61240DRVT enters undervoltage lockout (UVLO) when the input voltage falls below 2.0 V (typical falling threshold). It resumes operation once VIN rises above 2.1 V (typical rising threshold), as documented in Section 7.5 Electrical Characteristics. This hysteresis prevents oscillation near the cutoff point and protects the battery from deep discharge - a key feature for TPS61240DRVT in Li-ion systems.
Can the TPS61240DRVT drive a 250 mA load?
No, the TPS61240DRVT is rated for up to 200 mA continuous output current under nominal conditions (e.g., 3.6 VIN, 25°C). While the datasheet notes "up to 450 mA" for the broader TPS6124x family, the TPS61240DRVT variant is specifically characterized for 200 mA maximum - confirmed by its 500 mA input valley current limit and 200 mA output current spec in Table 7.5. For 250 mA, TPS61241DRVT is the validated alternative.
What package type is used for the TPS61240DRVT?
The TPS61240DRVT uses a 6-pin DSBGA (Die Size Ball Grid Array) package with nominal dimensions of 1.25 mm × 0.86 mm and 0.4-mm ball pitch. This ultra-compact, bottom-terminal package is distinct from the WSON option offered for other TPS6124x variants and is optimized for minimal PCB area in thin portable devices - a defining mechanical attribute of the TPS61240DRVT ordering option.
