The LTC3805EMSE#TRPBF is a synchronous monolithic dual-output step-down DC/DC switching controller with internal continuous mode (CM) and pulse skip mode (PSM) operation with an ultra-wide 4.5V to 44V input voltage range. This switching controller can provide up to 95 percent conversion efficiency with operating frequencies of up to 2.5MHz. It has a wide input voltage range and is ideal for automotive and telecom applications that require more stringent requirements for input voltage, current and noise. Additionally, its small footprint makes it ideal for applications where board space is at a premium.

The LTC3805EMSE#TRPBF is a two-output step-down DC/DC switching controller designed for synchronous operation. It contains an integrated high frequency oscillator and gate driver, which simplifies the design of power supplies. It is designed for a wide variety of applications, from consumer electronics and computers to telecom and enterprise systems. In addition, its dual output configuration allows for output voltages from 0.6V to 5.5V.

The LTC3805EMSE#TRPBF uses a dual-output synchronous architecture to automatically switch between low-side and high-side MOSFETs. In addition, it can be configured to operate in Continuous Mode (CM) or Pulse Skipping Mode (PSM). In the CM mode, both top and bottom MOSFETs remain continuously on, allowing for higher efficiency and lower output ripple. In the PSM mode, the top MOSFET will stay off when there is no need, providing higher efficiency under light load and low noise operation.

The LTC3805EMSE#TRPBF has a wide input voltage range of 4.5V to 44V and can operate up to a 2.5MHz switching frequency. It features a low quiescent current of 15µA under no-load conditions and comes in a tiny SOT-23 package. Additionally, it features an adjustable Soft-Start and variable dead-time to minimize in-rush current and prevent sub-harmonic oscillations. It also features over-voltage, under-voltage, and thermal protection to ensure safe and successful operation.

The LTC3805EMSE#TRPBF can be used in a wide variety of applications such as automotive and telecom, industrial, and medical systems. In automotive and telecom applications, this device can be used to improve regulator noise, efficiency and reduce power dissipation. It can also be used to provide a wide input voltage range to supply multiple power rails. Additionally, its dual output configuration allows for multiple power rails to be provided from a single voltage rail.

The LTC3805EMSE#TRPBF is the ideal device for wide input voltage range applications, offering increased efficiency and low output ripple.
