EP5358LUA

Application Field and Working Principle

The EP5358LUA is a DC/DC converter designed to provide a regulated output power with low noise characteristics, from a wide variety of AC and DC inputs. This includes the traditional 100W, 24V AC/DC, 5V DC power supply. The EP5358LUA is a powerful and reliable DC/DC converter, perfect for any application where a compact, high efficiency power solution is required.

The integrated circuit in the EP5358LUA is an optimization of the buck-boost topology, which allows the device to adjust the output voltage using two alternative switching circuits. The first stage is the buck circuit which steps down the input voltage as required. The second stage is a boost circuit which steps up the output voltage to accommodate changing input and output requirements. Both circuits are integrated within the same IC, providing a compact, efficient power solution.

The EP5358LUA offers high efficiency up to 96% and a fast response time, and is designed to operate with both AC and DC inputs. The input voltage range of 4 VDC -28 VDC; with an output voltage range of 0.5 VDC to 28 VDC, making it suitable for a wide range of applications involving regulated power supplies.

The EP5358LUA’s wide input range and adjustable output voltage make it an ideal choice for applications such as powering 5 VDC circuits, embedded systems, industrial, automotive, and portable systems.

The EP5358LUA is designed for low ripple output with minimal time delay. The switching frequency is adjustable within a range of 0.1 MHz - 2 MHz, ensuring the device can be adjusted to the most suitable frequency range for any application. The frequency of the device can be adjusted in two ways; by programming the on-chip registers or by using external resistors and capacitors.

The EP5358LUA integrates a range of additional features including a precision enable signal, an enable/disable switch, over-current sensing, temperature sensing and soft-start. Additionally, the device includes adjustable under-voltage lockout, over-voltage protection, and over-temperature protection.

The EP5358LUA provides a reliable and efficient power solution for applications involving regulated power supplies. The integrated buck-boost topology, wide input and output voltage range, and additional features make it a powerful choice for any application requiring a compact, high efficiency power solution.
