TPS81256SIPT

Изолированный DC/DC преобразователь, 2.5 В, 5.5 В, 1 Выход, µSIP, 9 вывод(-ов).

The TPS81256SIPT is a MicroSiP DC/DC Step-up Power Solution intended with switching regulator, inductor and input/output capacitors. Only a tiny additional output capacitor is required to finish the design. The TPS81256 is based on a high-frequency synchronous step-up DC/DC converter optimized for battery-powered portable applications. The DC/DC converter operates at a regulated 4MHz switching frequency and enters power-save mode operation at light load currents to maintain high efficiency over the entire load current range. The PFM mode extends the battery life by reducing the supply current to 43µA (typical) during light load operation. Intended for low-power applications, the TPS81256 supports more than 3W output power over a full Li-ion battery voltage range. Input current in shutdown mode is less than 1µA (typical), which maximizes battery life.
