LT8494HFE#PBF is a high-efficiency, monolithic, synchronous step-down switch-mode regulator from Linear Technology. This DC-to-DC converter is designed to deliver robust, low-noise power conversion. This device is ideal for powering very low-noise, low-power supply designs that require a short output rise time and accurate output voltage regulation.

The LT8494HFE#PBF is a synchronous buck switching regulator that combines a high-side and a low-side power MOSFET into a fully-integrated, monolithic PWM DC-to-DC converter. It also incorporates all the necessary control and protections circuits, making it very easy to use. This chip is optimized for Power over Ethernet (PoE) applications needing a regulated output voltage and high efficiency across a wide input voltage range. The LT8494HFE#PBF is rated for a wide input voltage range of 4.5V to 36V, making it suitable for use in high-power applications such as server power supplies.

The LT8494HFE#PBF features several features that facilitate precision control and high performance. The device offers adjustable output range of 1.212V to 40V, fast-transient response, and very low output voltage ripple, resulting in exceptional performance in high-efficiency power supplies.

The LT8494HFE#PBF integrates two separately-controlled outputs; a main output and an enable output. The main output is adjustable from 1.212V to 40V, and the enable output acts as an enable/disable control, allowing the user to switch the power supply on and off without needing an external control signal. The LT8494HFE#PBF can deliver up to 3A, and has over-current and over-temperature protections.

The LT8494HFE#PBF is ideal for Power over Ethernet (PoE) applications and other high-efficiency power supplies where load sharing is essential. The device integrates two separately-controlled outputs, allowing for load sharing and redundancy. The fast-transient response and low-noise operation make this chip an ideal choice for low-power, high-efficiency applications.

The LT8494HFE#PBF is a monolithic, synchronous buck regulator that is well suited for space-constrained applications where size and weight are important factors. It is available in a 3 mm x 3 mm, 8-pin HFE#PBF package, making it well suited for applications where high power density is required.

The LT8494HFE#PBF is well suited for use in a variety of power supply applications, from high-current power over Ethernet supplies to low-power, low-noise applications. Its fast transient response, adjustable output voltage range and low-noise operation make it an ideal choice for high-efficiency power supplies. With its fast-transient response, adjustable outputs, low-noise operation and integrated protection functions, the LT8494HFE#PBF is a great choice for many DC-to-DC converter applications.
