Low-power isolated DC-DC converters are compact and suitable for communication equipment, instrumentation, and industrial electronics. They can provide an ideal solution for space-critical applications. IDEALPLUSING offers a wide range of isolated DC-DC converters for you to choose from. This article will introduce some specific applications of these devices.
Unregulated vs. Regulated Converters
IDEALPLUSING offers both regulated and unregulated isolated DC-DC converters. The choice depends on the application. If the supply voltage is stable and the load remains relatively constant, an unregulated DC-DC converter is a good fit. This is because unregulated DC-DC converters also provide voltage level translation, galvanic isolation, and short-circuit protection (/P models), while costing much less than regulated DC-DC converters.
In contrast, if the supply voltage or load is unstable, a regulated converter is required, which is designed to maintain the output voltage at the desired value as the input voltage or load changes. A regulated DC/DC converter will maintain a fixed output voltage if the input voltage changes (such as when powered by a battery) or the load is variable (including no-load conditions).
In some low-power designs, a semi-regulated converter can provide the best compromise. A semi-regulated converter is an unregulated converter that uses a low dropout (LDO) linear regulator on the secondary side of the transformer to keep the output at the desired value regardless of load conditions. This solution has distinct advantages: if the load is suddenly removed, the output voltage remains regulated and the converter continues to be short-circuit protected. However, due to the additional regulation stage, the overall efficiency is reduced and the cost is increased compared to an unregulated converter.
Here is an isolated non-stabilized product, which is also a hot-selling product in the market recently, IPS-DTDYI24S1210.
It can adopt three control modes according to the needs. The PWM control mode has high efficiency and good output voltage ripple and noise. The PFM control mode has the advantage of low power consumption even when used for a long time, especially under light load.
PWM/PFM uses PFM control when it is converted to light load, and automatically converts to PWM control when it is heavy load. At present, DC-DC converters are widely used in mobile phones, MP3, digital cameras, portable media players and other products. It belongs to the chopper circuit in the circuit type classification.This product is mainly used in medical power supplies, high-speed communication buses, offline power solutions, motor drives and high-voltage use cases.
Finally, IDEALPLUSING provides non-isolated DC-DC converters that can be used for a variety of purposes. Isolated DC-DC converters have been widely used in many industrial and medical applications with various professional requirements. IDEALPLUSING has also optimized the design for these purposes and provides more regulated and unregulated converters.
