It is optimized for products powered by a one- • Up to 96% Efficiency Synchronous Boost cell Li-Ion battery, or a regulated power rail of 3.3 V. Converter The IC integrates a 5-A switch and is capable of delivering output currents up to 2.1 A at a 5-V output • 3.3-V to 5-V Power Conversion with 2.1-A Output with a 3.3-V input supply. The device is based on a Current quasi-constant on-time valley current mode control • Input Supply Voltage Supervisor with Adjustable scheme. The typical operating frequency is 2 MHz, Threshold/Hysteresis which allows the use of small inductors and • Power Save Mode for Light Load Efficiency capacitors to achieve a small solution size. The TPS61230 and TPS61231 provide an adjustable • Load Disconnect During Shutdown output voltage via an external resistor divider, and the • Output Over Voltage Protection TPS61232 provides a fixed output voltage of 5 V. • Programmable Soft Start During light loads, the TPS6123x automatically enters • Power Good Output power save mode for maximum efficiency at lowest • 2-MHz Switching Frequency quiescent currents. In shutdown, the load is completely disconnected from the input, and the input • Output Capacitor Discharge (TPS61231) current consumption is reduced to 1.5 µA typical. The • 3 mm x 3 mm x 0.9 mm VSON Package device integrates a precise low power EN comparator. The EN threshold as well as the 2 Applications hysteresis of the enable comparator are adjustable with external resistors and support application • Low Voltage Li-Ion Battery Powered Products specific system power up and down requirements. • USB Power Supply Other features like output over voltage protection, • Tablet PCs thermal shutdown protection, and a power good output are built-in. • Power Banks, Battery Backup Units • Industrial Metering Equipments The devices are available in a 3 mm x 3 mm x 0.9 mm VSON package.
