This makes it a perfect choice for a wide range of applications such as automotive, laptop battery management, industrial and consumer electronic products.The included features of the HPQ-12/25-D48PB-C make it suitable for applications including battery charging, optical isolation and power supply for various communications and gate drive. The HPQ-12/25-D48PB-C also offers the flexibility of built-in current and voltage isolation with 6V tolerant, thereby limiting the number of external components and simplifying the design.

Working Principle of HPQ-12/25-D48PB-C

The HPQ-12/25-D48PB-C works on an intermittent mode control method and uses a pulse code modulation (PCM) technique to convert a 12V input to 12V output power. It consists of a buck half bridge, a synchronous rectifier, an asynchronous rectifier, a compensation section and an output stage.The buck half bridge is composed of a series of switches which control the rectifier to maintain the output voltage and regulate the output current. When the input voltage is low, the synchronous rectifier is used to regulate the output current by providing a short circuit between the input and output of the converter.The asynchronous rectifier is used to limit the output current and provide an adjustable voltage regulation range. The synchronous rectifier and asynchronous rectifier both utilize a low switching frequency and allow the design to be optimized for maximum output power.The compensation section and the output stage of the HPQ-12/25-D48PB-C ensure the stability and accuracy of the output voltage by providing a fast and accurate transconductance control signal.

Conclusion

HPQ-12/25-D48PB-C is an ideal choice for various power management and control applications due to its flexibility, cost-effectiveness and high efficiency. Its built-in features make this DC/DC converter suitable for a variety of applications ranging from automotive to industrial and consumer market. The HPQ-12/25-D48PB-C uses intermittent mode control and a combination of synchronous and asynchronous rectifiers to deliver a continuous current up to 25W.
