Texas Instruments TPS61261 Tiny Low Input Voltage Boost Converter with 3.3 Output Voltage TPS61261DRVR

The TPS61261DRVR is a low input voltage boost converter designed for applications requiring a 3.3V output. It operates with an input voltage range from 0.8V to 4.0V and can deliver output currents up to 100mA while maintaining high efficiency, reaching up to 95%. The device features a quasi-fixed frequency PWM controller with synchronous rectification, which enhances efficiency across varying load conditions. It includes a programmable average output current capability from 10mA to 100mA and allows for adjustable output voltage through an external resistor divider. The TPS61261DRVR also incorporates advanced softstart, Power Save Mode for low load efficiency, and includes protections such as output overvoltage protection and undervoltage lockout. Packaged in a compact 6-pin WSON format, it is suitable for battery-powered devices, including personal medical products, LED drivers, and wireless headsets.
