Texas Instruments TLV61046ADBVR

Overview

TLV61046ADBVR from Texas Instruments is a highly integrated boost converter designed for PMOLED panels, LCD bias supplies, sensor modules, wearable devices, and portable medical equipment. The device supports a 1.8V to 5.5V input range, output voltage up to 28V, and integrates a power switch, rectifier diode, and input-to-output isolation switch for compact high-voltage step-up power designs.

As part of the Texas Instruments boost-converter portfolio, TLV61046ADBVR combines small external component requirements, 1.0MHz switching operation, internal soft start, true shutdown disconnection, and multiple protection features for portable and embedded power systems. For engineers reviewing the TLV61046ADBVR datasheet, TLV61046ADBVR pinout, TLV61046ADBVR application, or TLV61046ADBVR equivalent, this device is widely used in display bias supplies, PMOLED power rails, sensor power supplies, wearable electronics, and portable medical platforms.

Technical Context

In portable power systems, TLV61046ADBVR operates as a step-up DC/DC converter that raises a low input voltage from a lithium battery or two alkaline cells into a regulated higher-voltage output. This makes it useful for circuits that require voltage rails above the available battery voltage, such as PMOLED displays, LCD bias networks, and sensor modules.

The device integrates a 30V power switch, rectifier diode, and isolation switch, reducing external component count and simplifying PCB layout. The isolation switch disconnects the output from the input during shutdown, helping minimize leakage current and improve battery-powered system behavior.

TLV61046ADBVR is commonly used in wearable displays, portable instruments, medical sensors, compact embedded modules, handheld electronics, and low-power display-bias circuits requiring efficient high-voltage boost conversion.

Key Specifications

Pinout & Package

The TLV61046ADBVR pinout is optimized for compact boost-converter layouts and includes SW, GND, FB, EN, VOUT, and VIN pins in a 6-pin SOT-23 package.

For PCB implementation, the SW node should be kept compact, input and output capacitors should be placed close to the device, and the feedback path should be routed away from noisy switching traces to maintain stable regulation and reduce EMI.

Key Features

• Integrated boost converter supports output voltage up to 28V.
• 1.8V to 5.5V input range supports lithium battery and two-cell alkaline applications.
• Integrated power diode and isolation switch reduce external component count.
• True input-to-output disconnection during shutdown minimizes leakage current.
• 1.0MHz switching frequency allows compact external components.
• Internal 7ms soft start helps reduce inrush current during startup.
• Short-circuit, overvoltage, and thermal shutdown protection improve reliability.

Applications

Equivalent & Alternatives

When evaluating TLV61046ADBVR equivalent devices, engineers should compare input-voltage range, maximum output voltage, switch current limit, shutdown disconnection behavior, switching frequency, package size, and protection functions.

Compared with TPS61046, TLV61046ADBVR is optimized for TLV61046A-based portable display-bias and sensor-supply designs requiring integrated isolation switching and compact SOT-23 implementation. TLV61046ADBVR vs LT3461 selection depends on maximum output voltage, shutdown leakage requirements, switching frequency, external component selection, and PCB size constraints.

Quality

TLV61046ADBVR should be sourced as original Texas Instruments components through traceable and controlled supply channels. Quality verification procedures may include package inspection, top-mark validation, solderability testing, output-voltage verification, switching-function testing, shutdown-current checks, and incoming inspection according to portable power-system production requirements.

Because the device operates in a switching boost-converter environment, stable layout, correct inductor selection, proper capacitor placement, controlled feedback routing, and thermal management help maintain output regulation, EMI performance, and long-term reliability. Traceable sourcing supports industrial manufacturing quality and reduces counterfeit supply-chain risk.
