Product details
Overview
TPS61240DRVR from Texas Instruments is a synchronous step-up DC-DC converter optimized for single-cell Li-Ion/Li-Polymer and three-cell alkaline/NiMH battery-powered portable devices. It delivers a fixed 5.0 V ±2% output at up to 200 mA load, operates from 2.3 V to 5.5 V input, achieves >90% efficiency at nominal conditions, and features 3.5-MHz quasi-constant on-time valley current mode control.
For engineers reviewing the TPS61240DRVR datasheet, TPS61240DRVR pinout, TPS61240DRVR application, or TPS61240DRVR equivalent, this page provides verified technical context, real-world design meaning of key specs, validated pin functions, confirmed alternative options, and supply-chain support details specific to the DSBGA-6 (1.25 mm × 0.86 mm) variant.
Technical Context
The TPS61240DRVR uses a quasi-constant on-time valley current mode control architecture that enables fast line/load transient response with minimal external components. Its internal softstart ramps output voltage to 5 V in 250 μs, while automatic PFM/PWM mode transition maintains high efficiency across 100 µA–200 mA loads.
It integrates high-side and low-side N-MOSFETs (290 mΩ and 250 mΩ typical RDS(on)), undervoltage lockout (2.1 V rising threshold), input overvoltage protection (6.0 V trip), thermal shutdown (140 °C), and load disconnect during shutdown - eliminating battery drain via the inductor path when disabled.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0 V ±2% - ensures stable USB-OTG/HDMI bus compliance without external feedback resistors. |
| Input Voltage Range | 2.3 V to 5.5 V - supports full discharge curve of one-cell Li-ion (3.0–4.2 V) and three-cell alkaline (3.0–4.5 V). |
| Max Output Current | 200 mA at VIN ≥ 3.2 V - sufficient for USB-OTG host mode and portable HDMI sink operation. |
| 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 life in standby states of handheld devices. |
| Shutdown Current | 1.5 µA - ensures negligible battery leakage during system sleep or off-mode. |
| Efficiency | >90% at 150 mA, VIN = 3.6 V - minimizes thermal stress and maximizes runtime in space-constrained portable designs. |
Pinout & Package
TPS61240DRVR is packaged in a 6-pin DSBGA (Die Size Ball Grid Array) with 1.25 mm × 0.86 mm body size and 0.4-mm pitch. This ultra-compact package supports high-density PCB layouts in mobile and wearable applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN | Enable input | Positive logic: high ≥1.0 V enables regulation; low ≤0.4 V forces shutdown with <2 µA IQ. |
| FB | Feedback input | Internally connected to 5.0 V reference; must be tied directly to VOUT for fixed-output operation. |
| GND | Power and signal ground | Common return path for input, output, and internal control circuits; requires low-impedance PCB connection. |
| L | Inductor switch node | Connects to boost inductor; carries high di/dt switching current; requires short, wide trace routing. |
| VIN | Input supply | Accepts battery or source (2.3–5.5 V); requires ≥2.2 µF ceramic capacitor placed adjacent to pin. |
| VOUT | Regulated output | Delivers 5.0 V ±2%; presents high impedance during shutdown to enable back-driving by alternate supplies. |
Key Features
| Feature | Design Value |
|---|---|
| Automatic PFM/PWM mode transition | Maintains >85% efficiency down to 100 µA load without external mode control circuitry. |
| Load disconnect during shutdown | Eliminates reverse current path through inductor and rectifier, preventing battery drain in off-state. |
| Internal softstart (250 µs) | Limits inrush current to protect weak battery sources and avoids input voltage sag during startup. |
| Low ripple power save mode | Reduces output voltage ripple to ~0.015 × VOUT (75 mVpp) during light-load PFM operation. |
| Three external component requirement | Only needs one MLCC inductor (1 µH) and two ceramic caps (2.2 µF CIN, 4.7 µF COUT) for full functionality. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-up converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS61241DRVR | Higher input valley current limit (600 mA vs. 500 mA); same 5 V output and DSBGA-6 package. | Supports up to 300 mA load at VIN ≥ 3.2 V - suitable where higher peak current is required. | Select TPS61241DRVR only if design demands >200 mA sustained output under low-input conditions. |
| TPS61291DRVR | Lower quiescent current (1.2 µA shutdown, 15 µA operating); same 5 V output, but WSON-6 (2 mm × 2 mm) package. | Optimized for ultra-low-power wearables; lacks load disconnect feature - VOUT remains connected to VIN during shutdown. | Choose TPS61291DRVR only when minimum IQ is critical and load disconnect is not required. |
Compared with TPS61240DRVR, TPS61241DRVR offers higher current capability in identical footprint, while TPS61291DRVR trades load disconnect and compact DSBGA for lower quiescent current and larger WSON packaging - making each suitable for distinct power budget and board-space constraints.

FAQ
What is the output voltage tolerance of the TPS61240DRVR?
The TPS61240DRVR provides a fixed 5.0 V output with total DC accuracy of ±2% over temperature, line, and load conditions - verified per TI SLVS806D datasheet Section 7.5. This tight tolerance ensures reliable operation of USB-OTG and HDMI interfaces without external trimming. The TPS61240DRVR achieves this using an internal resistor divider and precision bandgap reference, eliminating need for external feedback components.
Does the TPS61240DRVR support load disconnect during shutdown?
Yes, the TPS61240DRVR presents high impedance at the VOUT pin when disabled via the EN pin, fully disconnecting the load from the input source. This prevents battery drain through the inductor and synchronous rectifier during system sleep. Verified in datasheet Sections 1, 3, and 9.3.7, this feature is intrinsic to the TPS61240DRVR's architecture and requires no external MOSFET or control logic.
What is the recommended inductor value for the TPS61240DRVR?
Texas Instruments recommends a 1.0 µH shielded MLCC inductor (e.g., TOKO MDT2012-CH1R0AN) for the TPS61240DRVR, optimized for its 3.5-MHz switching frequency and 200 mA load capability. The datasheet specifies inductance range of 0.4–1.5 µH, but 1.0 µH balances efficiency, size, and transient response. Using values outside this range may degrade efficiency or cause instability in the TPS61240DRVR's valley current mode control loop.
Can the TPS61240DRVR operate from a 2.3 V input?
Yes, the TPS61240DRVR is fully specified to operate from 2.3 V to 5.5 V input, including at the 2.3 V minimum. At this voltage, it delivers up to 200 mA into 5 V with >85% efficiency (per Figure 2). Its undervoltage lockout releases at 2.1 V rising threshold, allowing operation down to near-dead battery levels - critical for maximizing runtime in alkaline- or NiMH-powered devices using the TPS61240DRVR.
Is the TPS61240DRVR pin-compatible with the TPS61241DRVR?
Yes, the TPS61240DRVR and TPS61241DRVR share identical pinout, package (DSBGA-6), and footprint - both are drop-in replacements in layout. Their only functional difference is input valley current limit (500 mA vs. 600 mA), which affects maximum sustainable output current under low-VIN conditions. No PCB changes are required when substituting TPS61241DRVR for TPS61240DRVR, provided the higher current capability is needed and thermally validated.
