DC-DC converters are commonly used in a variety of electronic systems, including automotive, industrial and consumer electronics. The PH300F110-15 DC-DC converter is a high efficiency, non-isolated flyback DC-DC converter that is designed to provide regulated output voltage from an unregulated DC input voltage. It is capable of delivering up to 15 Watts of output power at a voltage range of 5V to 48V input, with an output current of up to 3A.

Application Field

The PH300F110-15 is well suited for applications in the home or workplace, such as powering a variety of devices and peripherals, including laptops, LCD displays, digital cameras, scanners, and printers. It is also commonly used as a step-down converter for automotive applications, including automotive infotainment systems, LED lighting, power management systems and battery chargers.

The PH300F110-15 is well suited for industrial applications including industrial sensors, control systems, lab instrumentation, networking platforms, process control systems and motor control systems.

Working Principle

The PH300F110-15 employs a buck-boost topology to extract power from an unregulated DC input voltage. The input voltage is first converted into a high power square wave by an electronic switch, and then rectified by a diode to provide energy to the output capacitor. This action is called the flyback operation and is repeated many times to increase the output power.

The output voltage is then fed back to the primary side through an opto-coupler in the form of a voltage waveform. This waveform is compared to a reference voltage set by the user, and the output voltage is regulated accordingly by adjusting the duty cycle of the input signal. When the two signals match, the output voltage is at the desired value.

The converter also features a built-in soft start circuit, which prevents the output voltage from exceeding a predefined limit at start-up. It also has a built-in thermal shutdown circuit, which will shut down the converter in the event of an over-temperature condition.

The PH300F110-15 DC-DC converter can be used in many applications, from consumer electronics to automotive and industrial systems. Its high efficiency and reliable operation make it a popular choice for powering a variety of devices and peripherals.
