The TPS61256YFFT from Texas Instruments is a high-efficiency step-up (boost) converter suitable for battery-powered portable applications. It operates at a 3.5 MHz switching frequency and provides a fixed 5V output voltage.
Key electrical specifications include a wide input voltage range of 2.3V to 5.5V, supporting VIN >= VOUT operation. It can deliver up to 800mA at 4.5V output with VIN >= 2.65V, and up to 1000mA at 5.0V output with VIN >= 3.3V. Peak output current can reach 1500mA under similar conditions. The device boasts 93% efficiency at 3.5MHz operation and features low quiescent currents of 21µA in standby and 37µA in normal operation.
Designed for minimal component count, the TPS61256YFFT requires only three external surface-mount components, enabling a total solution size of less than 25 mm². It includes features like selectable standby or true load disconnect during shutdown, thermal shutdown, and overload protection. The device is housed in a compact 9-pin NanoFree™ (CSP) DSBGA package, measuring 1.2mm x 1.3mm, making it ideal for space-constrained designs.
This boost converter is suitable for applications requiring a regulated output voltage from a lower or fluctuating input source, such as mobile phones, digital cameras, and other portable electronic devices.
