| Description | The TLV61046ADBVR is a highly integrated step-up DC/DC boost converter from Texas Instruments, designed to generate high output voltages from low-voltage battery and system power rails. The device integrates a power switch, rectifier power diode, and input-to-output isolation switch, reducing external component count and enabling compact boost power supply designs. The TLV61046ADBVR operates from an input voltage range of 1.8V to 5.5V during startup and can continue operating with an input voltage as low as approximately 1.6V after startup. This wide low-voltage input range makes the device suitable for Li-ion batteries, two-cell alkaline battery systems, regulated 3.3V rails, and other low-voltage power sources. The converter supports an output voltage of up to 28V, allowing low-voltage sources to supply circuits requiring substantially higher operating voltages. The minimum programmable output voltage is approximately 3.3V, providing flexibility for a wide variety of step-up conversion applications. The TLV61046A integrates a 30V internal power switch with a typical switch current limit of approximately 980mA. Integrating the switching MOSFET eliminates the need for an external power transistor and helps reduce PCB area, component count, and overall power supply design complexity. A significant feature of the TLV61046ADBVR is its integrated rectifier power diode. Conventional nonsynchronous boost converters normally require an external Schottky diode, while the integrated diode in the TLV61046A further reduces the number of external power components required by the converter. The device also integrates an input-to-output isolation switch. When the converter is disabled, this switch provides true disconnection between the input and output, preventing the normal boost-converter current path from allowing the input voltage to remain present at the output. This true load-disconnect capability is particularly useful in battery-powered equipment where downstream circuitry must be completely disconnected during shutdown. It helps reduce standby leakage and prevents unwanted powering of the load when the boost converter is disabled. The TLV61046ADBVR operates at a switching frequency of approximately 1.0MHz. The high switching frequency allows designers to use relatively small inductors and capacitors, supporting compact power supply layouts for portable and space-constrained electronic products. The converter can achieve efficiency of up to approximately 85% under suitable operating conditions, including a 3.6V input and 12V output configuration. Actual efficiency depends on input voltage, programmed output voltage, output current, inductor characteristics, PCB layout, and other operating conditions. The TLV61046A supports an especially simple 12V output configuration. Connecting the FB pin to VIN selects the device's internal default 12V output setting, allowing a 12V boost converter implementation with only a small number of external components. For other output voltages, the feedback network can be configured to establish the required regulated output. The device provides approximately ±2.5% output voltage accuracy, supporting stable bias and auxiliary supply generation for analog, display, sensor, and embedded electronic circuits. The converter incorporates a power-save operating mode that improves efficiency under light-load conditions. This feature is particularly valuable in battery-powered equipment where the load can vary significantly between active and standby operating states. An integrated 7ms soft-start function controls the startup process and reduces input inrush current while the output voltage rises. Controlled startup helps minimize disturbances on the upstream supply and reduces electrical stress on power components. The TLV61046ADBVR includes comprehensive protection features such as output short-circuit protection, output overvoltage protection, and thermal shutdown protection. These functions help protect both the converter and the surrounding circuitry during abnormal operating conditions. The device operates over a temperature range of -40°C to +125°C, making it suitable for consumer, industrial, portable, instrumentation, and embedded applications requiring reliable operation across a broad temperature range. The TLV61046ADBVR is supplied in a compact 6-pin SOT-23 package, identified by Texas Instruments package code DBV. The package footprint is approximately 2.9 × 2.8mm, allowing the converter to be integrated into space-constrained PCB designs. The R suffix identifies the large tape-and-reel version. The TLV61046ADBVR is supplied in a standard package quantity of 3000 pieces per reel, making it suitable for automated high-volume surface-mount production. The combination of 1.8V to 5.5V input operation, output voltage up to 28V, 980mA typical switch current, 1MHz switching frequency, integrated power diode, integrated isolation switch, true load disconnect, power-save operation, soft start, and comprehensive protection functions makes the TLV61046ADBVR a highly integrated solution for generating higher-voltage rails from low-voltage power sources. The TLV61046ADBVR is widely used in PMOLED panel power supplies, LCD bias supplies, sensor modules, portable instrumentation, battery-powered electronics, Li-ion battery systems, alkaline battery equipment, display bias circuits, analog bias supplies, wearable electronics, handheld equipment, embedded systems, industrial sensors, data acquisition equipment, and other low-voltage to high-voltage DC/DC conversion applications. |
