DC DC converters are devices that are used to convert direct current (DC) to alternating current (AC) or vice versa. The BWD1205 is a type of DC DC converter that is commonly used in industrial and commercial applications. It is a non-isolated, switch-mode power supply that is designed to convert regulated DC voltage from a wide input voltage range. This converter is reliable, durable, and cost effective, making it the ideal choice for many applications.

Features of the BWD1205

The BWD1205 is a universal input DC DC converter that features a wide input voltage range of 4.5 to 40 VDC. The converter can produce a maximum continuous output power of 5 W and is available in two different package types – enclosed and open frame. The enclosed type comes with an output voltage range of 5 to 18 VDC and is designed for applications with lower input/output voltage differences. The open frame type has an output voltage range of 2.5 to 36 VDC and is suitable for applications with higher input/output voltage differences. Other features of the BWD1205 include wide operating temperature range of -40°C to +85°C, an operating efficiency of up to 91%, remote on/off control, and short-circuit protection.

Applications and Working Principle of the BWD1205

The BWD1205 is well suited for numerous applications including industrial, automotive, computer, communication, medical, and consumer electronics. It can be used for a wide range of DC-to-DC conversion applications, such as voltage step-down, voltage step-up, DC/DC multiple outputs, and LED driver. The device is also available with various extension options, such as enhanced EMI filters, current sense, and active current sharing.

The BWD1205 is based on the flyback topology, which is a type of switching converter in which energy is transferred from the input source to the output load by the action of an inductor, a switch, and an energy storage capacitor. When the switch is closed, the input voltage is applied to the primary winding of the converter’s transformer and energy is stored in the inductor. When the switch is opened, energy is released from the inductor and transferred to the output load through the secondary winding of the transformer and the energy storage capacitor.

The BWD1205 uses pulse width modulation (PWM) to control the output voltage. This means that, when the PWM signal rises, the duty cycle of the switching converter increases and the output voltage is adjusted accordingly – and vice versa. The pulse width modulation of the BWD1205 is regulated by an integrated control IC, which compensates for varying input voltage and load conditions to ensure that the output voltage remains stable.

Conclusion

The BWD1205 is a universal input DC DC converter that offers an efficient, reliable, and cost-effective solution for various industrial and commercial applications. It is based on the flyback topology and uses pulse width modulation to control the output voltage. The device is available in several different package types with a range of extension options. With its wide input voltage range, efficient operation, and robust design, the BWD1205 is the ideal choice for many applications.
