DC DC Converters

DC DC converters are a type of electronic component used to convert a current of one type of voltage into an opposite type of current, such as AC to DC or DC to AC. One example of a DC DC converter is the BP1301-9RG, which is an integrated high-performance DC/DC switched-mode power supply for digital systems, with a maximum voltage output of 12V.

BP1301-9RG Application Field

The BP1301-9RG is usually used in power sensitive devices such as fuel cell systems, consumer appliances, embedded systems, distributed power systems, sign systems, and wireless systems. It is most often used in applications where a high efficiency, low power consumption, and a small form factor are required. The BP1301-9RG is also suitable for industrial and automotive applications, due to its high level of reliability.

BP1301-9RG Working Principle

The BP1301-9RG is a switching power supply that uses a power transformer to reduce the input voltage, followed by an integrated power switch, an inductor, and a diode to convert the reduced input voltage into a higher DC voltage. This is done by controlling the on/off time of the switch, which propels the current into the inductor and then into the diode.

The switch is controlled using Pulse Width Modulation (PWM), which is a process of controlling the width of the pulses sent to the switch. This is done by comparing the output voltage with a reference voltage. When the output is higher than the reference voltage, the pulses sent to the switch are narrower, and when it is lower, the pulse width is widened. In this way, the output voltage is regulated, and an efficient conversion of current is achieved.
