TLV61046ADBVR Boost Switching Regulator IC
The TLV61046ADBVR from Texas Instruments is a highly integrated, high-efficiency boost (step-up) DC-DC converter designed to generate stable, high output voltages from low-voltage sources for space-constrained and battery-powered applications . Housed in a compact 6-pin SOT-23 package measuring 3mm x 3mm, this device features a wide input voltage range of 1.8V to 5.5V (extendable down to 1.6V after startup) and can deliver an adjustable output voltage up to 28V . It integrates a 30V power switch, a rectifier diode, and an input-to-output isolation switch, significantly reducing external component count . Key specifications include a typical switch current limit of 980mA, a fixed switching frequency of 1.0 MHz (typical), and a high efficiency of up to 85% at 3.6V input and 12V output .
This converter delivers exceptional power density and design simplicity through its high level of integration . The integrated power diode and isolation switch eliminate the need for external Schottky diodes and load disconnect circuits, saving board space and reducing the bill of materials . Its high switching frequency (1.0 MHz) allows for the use of small, low-profile inductors and capacitors, enabling ultra-compact power supply designs . The device incorporates advanced power management features, including a power-save mode at light loads to maintain high efficiency across a wide load range and an internal 7ms soft-start timer to limit inrush current during startup .
The TLV61046ADBVR is engineered for applications requiring a compact, efficient boost converter to generate moderate power at high voltages from low-voltage batteries or rails . Its primary use is in display power supplies, specifically for PMOLED panels and LCD bias supplies, where it generates the required high positive and negative bias voltages . It is also ideal for portable and wearable devices, sensor modules, and portable medical equipment that need to boost a single-cell Li-ion or two-series alkaline battery voltage to power various peripherals . Additionally, it finds applications in driving piezoelectric actuators, flash LEDs, and as a general-purpose high-voltage rail generator in industrial and consumer electronics .
