For example, it can be used as a regulator for a power supply module in a DSL modem, or as the output regulator for a Bluetooth module.
The NCP1402SN40T1G can also be used as a main power regulator for portable devices, such as GPS systems, mobile phones and digital cameras. This is because of its superior efficiency and wide input voltage range, which makes it suitable to be used in different operating environments and with varying input power sources. This makes the NCP1402SN40T1G an ideal choice for portable gadgets and devices that utilise a wide variety of input sources, such as USB ports, car chargers and solar panels.
Working Principle of NCP1402SN40T1G
The NCP1402SN40T1G is a DC/DC synchronous switching regulator which uses Pulse Width Modulation (PWM) technique to generate a stable output voltage from a wide variety of input voltages. It uses two switches, a buck switch and a boost switch in order to regulate the output voltage. In a buck configuration, the watt switch is used to lower the input voltage, whereas in a boost configuration the boost switch is used to increase the output voltage.
When the PWM signal is generated, the buck or boost switch is pulled high and low to control the output voltage. The average voltage of the output voltage is equal to the control voltage multiplied by the duty cycle of the PWM signal. The NCP1402SN40T1G allows the user to program the control voltage and the duty cycle, enabling a wide input voltage range and precise output voltage.
The NCP140SN40T1G also features a range of protection features, including over-current, over-temperature and under-voltage protection. This ensures that the device is protected from potential damage due to over-current, over-temperature or under-voltage conditions.
Conclusion
In conclusion, the NCP1402SN40T1G is a high-efficiency, high-performance, wide input voltage range and low quiescent current DC/DC synchronous switching regulator. It has a wide range of applications in automotive, telecommunications, computer equipment, and other industrial and consumer electronics applications. Due to its wide input voltage range and low quiescent current, it is suitable for use in portable gadgets and devices utilizing various input sources.
The NCP1402SN40T1G uses Pulse Width Modulation (PWM) technique to control the output voltage, in combination with buck and boost switches.
