The TPS61141 is a dual-output boost converter designed to operate within an input voltage range of 2.5 V to 6 V. It features two outputs, each capable of delivering up to 27 V and 700 mA. The device integrates a power MOSFET and a power diode, eliminating the need for external active components. It employs pulse frequency modulation (PFM) for efficient operation across a wide load range and can switch at a frequency of 1.2 MHz when configured for maximum output current. This boost converter is particularly suitable for applications involving OLED and white LED (WLED) drivers, allowing for individual programmability of voltage and current outputs. It includes built-in short-circuit protection, overvoltage protection, and a soft-start feature to enhance reliability. The TPS61141 is housed in a compact 10-pin, 3 mm x 3 mm QFN package, making it a space-efficient solution for portable devices such as clamshell phones with OLED/LCD screens.
