SLDN-20D1ALG

DC DC Converters

The SLDN-20D1ALG is a DC DC converter that offers a viable solution for a vast range of applications due to its high power efficiency, which ranges from 70 to 90% regardless of the operating conditions. Its wide input voltage range, up to 48 volts, makes it suitable for most DC power systems. The SLDN-20D1ALG is also able to supply up to a 20A rated load current over a wide temperature range.

The SLDN-20D1ALG utilizes an advanced, high-efficiency, asynchronous buck chopper circuit design to achieve its operating characteristics. This switching technique transfers power from the primary (high side) of the circuit to the secondary (low side) by connecting the two sides through an inductor. The switches are activated at the optimum time to ensure maximum efficiency. The magnetically isolated intermediate transformer further isolates the primary and secondary circuits, making the circuit highly robust and reliable. The transformer also helps reduce the size and complexity of the circuit.

The SLDN-20D1ALG is designed to operate in harsh industrial environments and has built-in features to ensure consistent performance under a wide range of temperatures. The DC input voltage sensing circuit automatically increases the primary oscillator frequency to ensure reliable operation in high temperatures and low input voltages. An internal trim resistor allows fine tuning of the output voltage, allowing precise control over the output voltage under varied operating conditions. An Over Current Protection Circuit (OCP) also ensures reliable and safe operation.

The SLDN-20D1ALG utilizes cascade soft start to ensure a smooth, power-up transition. This provides a gradual increase in output current to prevent excessive overshoot of the output voltage, which may harm the load or the power supply. The steady-state power supply start-up time is also vastly reduced, allowing for faster and smoother operation even under heavy load conditions. The SLDN-20D1ALG can be used in a variety of applications. It can be used for telecommunications systems, industrial control systems, medical equipment, LED lighting systems, and more. It is also suited for applications that require high efficiency and flexible operating parameters such as power factor correction and frequency conversion.

Overall, the SLDN-20D1ALG is an advanced, high-efficiency, cost-effective, and reliable DC-DC converter for a wide range of applications. It utilizes advanced design techniques, allowing it to achieve excellent performance under a wide range of temperatures and input voltages. Its features, such as the OC protection circuit and cascade soft start, ensure safe and reliable operation. Consequently, the SLDN-20D1ALG is an excellent choice for industrial, medical, and other high-efficiency applications.
