The Texas Instruments TPS61258YFFR is a high-efficiency step-up (boost) converter designed for battery-powered portable applications. It features a fixed output voltage of 4.5V and can deliver up to 3.9A of switch current. The device operates with a wide input voltage range from 2.3V to 5.5V, making it suitable for various power sources.
With a switching frequency of 3.5MHz, the TPS61258YFFR achieves up to 93% efficiency and requires only three external components for a compact solution size of less than 25 mm². It offers low quiescent current in both standby (21µA) and normal operation (37µA) modes. The converter includes thermal shutdown and overload protection for reliability.
Packaged in a 9-pin DSBGA (WCSP), the TPS61258YFFR is designed for surface-mount applications. Its small footprint and high performance make it ideal for space-constrained designs.
