DC DC Converters: JW150C1 Application Field and Working Principle A DC to DC converter, such as the JW150C1, is a device which converts direct current (DC) voltages or currents from one value to another. It is typically used to provide power for numerous electronic circuits and components, such as embedded systems and microcontrollers, various sensors, and communication systems, to name a few.DC-DC converters are typically classified according to their topology. The JW150C1 utilizes the buck-boost topology, a type of non-isolated switching converter with a low output voltage. In this topology, the input voltage is stepped down or up depending on the required output voltage by controlling the on and off time of a switching device.The JW150C1 is a highly efficient DC-DC converter with a maximum efficiency of 95%. It has an operating temperature range from -40°C to +105°C with an input voltage range of 4.5V to 28V and an output voltage range of 2.5V to 28V. It features wide input voltage and very low standby current of 15µA, as well as over-current protection, over-temperature protection, and under-voltage lock out (UVLO). The JW150C1 is suitable for numerous applications using solar cells, lithium ion batteries, and distributed power systems. Its wide range of voltage input and output makes it ideal for use in a variety of battery-powered systems, such as medical devices, robots, consumer electronics, and automotive electronics. The circuit diagram of a buck-boost converter is as shown here. The circuit is composed of three main components: the input source, the switch, and the output load. The input voltage is applied to the switch through the input source, and the switch is controlled by a pulse width modulation (PWM) signal. The switch regulates the power flow between the input and the output load. On the output side, an inductor is used to smooth the current for cleaner output voltage. The output voltage is then regulated by the feedback loop and the output capacitor. The working principle of the JW150C1 is shown here. The switching device is controlled by a PWM sensor which, based on its internal algorithms, will adjust its duty cycle to control the power flow from the input to the output. When the duty cycle is high, the power flows from the input to the output, resulting in an output voltage higher than the input. When the duty cycle is low, the power flows from the output to the input, lowering the output voltage.The LED in the diagram indicates the operating status of the JW150C1. When the LED is on, it means that the converter is in the normal operating state, and when the LED is off, it means that the converter is in the fault state. If the LED is off, the user can reset the converter. In addition to regulating the output voltage, the JW150C1 also features over-current protection. This is done using a current monitor circuit, which senses the current flowing through the converter. When the monitored current exceeds a set threshold, the converter will immediately shut down the switching device to protect its components from being damaged by excessive current. The JW150C1 also has over-temperature protection, which means that it will shut down the switching device if its internal temperature exceeds a certain point. This prevents the converter from becoming damaged due to excessive heat.Finally, the JW150C1 features a UVLO, which ensures that the output voltage cannot be higher than the input voltage. This is done by monitoring the input voltage and stopping the switching device if the input voltage is too low. In conclusion, the JW150C1 is a highly efficient DC-DC converter with a wide range of voltage input and output suitable for a variety of applications. Its features, such as over-current protection, over-temperature protection, and UVLO, make it safe and reliable.
