DC to DC converters are power electronic devices, which are used to convert one form of DC Power into another form of DC power. SPAN02A-15 is a DC to DC converter used in the field of high-frequency, small, low power, and medium-powerDC-to-DC conversion. It is used in applications such as automotive electronics, consumer electronics, smaller distributed power systems, and other DC to DC power management applications.
The SPAN02A-15 features maximum power of 15 watts, and a switching frequency of 2000 kHz. The converter provides adjustable voltage from 4.5 volts to 14 volts, and a maximum output current of 1 A. Its main features include an integrated step-up DC/DC power converter, excellent noise immunity, and wide temperature range from -40°C to +85°C. It also provides excellent efficiency, an integrated loop compensation, soft-start, and short-circuit protection, with a maximum output power of 15 watts, and a 0.2-Ohm internal switch.
The basic working principle of the SPAN02A-15 is as follows. Firstly, the input voltage from the battery is applied to the primary winding, while the secondary winding is connected to the battery. Then, the primary side voltage is divided into two parts, one is applied to the switch and the other to the leakage inductance. When a signal is applied on the control pin, the switch turns on and conducts current, causing the current to pass through the primary winding. This causes the magnetic flux produced by the primary winding to be added to the flux produced by the secondary winding, thus increasing the voltage in the secondary winding.
At the same time, the current flowing through the switch starts to decrease. When the current flows through the switch will decrease up to zero, it will turn off and no longer conduct current, resulting in the switch voltage rising up to the input voltage level. The current decreases due to the fact that the primary winding’s benefits from the additional flux from the secondary side, and the leakage inductance will not allow the current to pass through the primary winding. The flux will now reduce to its original level, and the secondary winding’s voltage will no longer increase. Then, the switch will not conduct current and the voltage on the primary side will remain at the input voltage level.
When the switch is turned off, the current on the secondary side will stay the same until the primary current reduces to zero, which departs the other side of the magnetizing inductance. At this point, the switch will be turned on and the process will start again. Thus, the current will build up a voltage across the secondary side, and the secondary voltage will increase.
The SPAN02A-15 is a great example of a DC to DC converter. It is extremely efficient, and provides excellent noise immunity, wide temperature range, soft-start, and short-circuit protection. It also has an integrated loop compensation and step-up DC/DC power converter that makes it suitable for a variety of application in the fields of automotive electronics, consumer electronics, and other distributed power management systems.
