The LTC3400BES6#TRPBF is a high-efficiency, fixed-frequency, synchronous step-up DC/DC converter from Linear Technology, designed to provide a compact and power-efficient solution for portable electronic devices. This tiny device is capable of delivering a continuous output current up to 300mA with a corresponding input voltage range of 1.6V to 4.5V, making it an ideal choice for single-cell Li-Ion or multi-cell alkaline/NiMH applications.

It comes in a low-profile (1mm) ThinSOT package, which is perfect for space-constrained applications. The LTC3400BES6#TRPBF operates at a fixed frequency of 1.2MHz, allowing the use of tiny, low-cost capacitors and inductors while minimizing noise sensitive to RF and other high-frequency circuits.

With an internal synchronous rectifier, the LTC3400BES6#TRPBF improves efficiency and eliminates the need for an external Schottky diode. This feature not only reduces the overall component count but also conserves board space and simplifies the design process. Its high efficiency can be maintained over a wide range of output currents due to its low RDS(ON) internal switches.

The device includes features such as a low-battery detector, which signals when the input voltage falls below a programmable threshold, and a shutdown mode that reduces quiescent current to less than 1µA, further extending battery life in portable systems. Additionally, the LTC3400BES6#TRPBF has internal soft-start functionality that limits inrush current during startup.

Other notable features of the LTC3400BES6#TRPBF include current mode operation for excellent line and load transient response, and thermal protection. It is a versatile power solution that meets the needs of a wide range of applications such as handheld devices, wireless mice, small LCD displays, and backup power supplies.

Overall, the LTC3400BES6#TRPBF from Linear Technology is a reliable and high-performance step-up DC/DC converter that offers a compact, efficient, and feature-rich solution for powering portable electronics.
