The ICH10048S05 is suitable for a wide range of applications, such as consumer, industrial and automotive applications. It’s mostly used in portable media players, laptop computers, mp3 players, medical equipment, and battery-powered products. It is also suitable for automotive and industrial applications such as LED lighting, solar power converters, DC to DC converter, and more.

Working Principle of ICH10048S05

The ICH10048S05 is an integrated buck converter that consists of an integrated high-side MOSFET and a PWM current sensing circuit. The integrated MOSFET has high operating temperature and excellent thermal performance, enabling the device to achieve high efficiency. The device can also operate with wide input voltage (0.85V to 5.5V) and offers current limit protection, making it suitable for a wide range of applications.

The ICH10048S05 follows the “buck” working principle, a type of DC to DC conversion. It works by using a switching transistor and inductor to reduce a higher input voltage to a lower output voltage. The switching transistor is turned on and off at a fixed frequency, creating a voltage waveform that is then used to drive the inductor and reduce the input voltage. The inductor current changes to achieve a stable output voltage.

The ICH10048S05 also features current-sensing circuit that can detect output current and turn the switching transistor off when the current exceeds the rated limit. This protection circuitry ensures that the device will not be damaged by excessive current. Additionally, it also provides features such as under voltage lockout protection, over-temperature protection, and short circuit protection to prevent any damage to the device.

Conclusion

The ICH10048S05 is a DC-DC buck converter designed for battery powered applications. It is suitable for a wide range of applications, such as consumer, industrial, and automotive applications. This device features adjustable thermal performance, current sensing circuit, and a wide input voltage range. It operates using the “buck” working principle and offers protection circuitry such as over-temperature and current limit protection. The ICH10048S05 is an ideal device for providing a stable output voltage for battery powered system.
