CHL8326-19CRT is a high performance DC-DC switching controller that is widely used in low voltage applications due to its small size and wide range of input supply voltage. It is a member of a larger family of switching regulator solutions developed by Celano Semiconductor, which include both linear and switching regulators. The CHL8326-19CRT operates with a maximum input supply voltage of 19V and offers adjustable output current up to 25A.

The CHL8326-19CRT has several advantages over other switching controllers, including a low quiescent current draw, high efficiency, and of course, the ability to handle a variety of input supply voltages. It also has built-in protection features, such as over-current, under-voltage, and thermal shutdown. Additionally, it can be used in a variety of applications, including automotive, industrial, communications, and medical.

The working principle of the CHL8326-19CRT is relatively simple. It is a buck converter, which means that it takes an input voltage and reduces it to a smaller amount (the output voltage). To do this, it uses a switching element to rapidly switch the input voltage on and off. This process causes the voltage to ripple slightly, and then the output voltage is regulated using a feedback loop that compares the output voltage to a reference voltage. This loop will then adjust the duty cycle of the switching element in order to maintain the desired output voltage.

The CHL8326-19CRT switch controller is ideal for DC-DC converters and other applications where a high input voltage can be reduced to a lower but still regulated voltage. It is also a good choice for applications where a high current draw is required, as it can handle up to 25A. Its many features, such as its adjustable switching frequency and its wide input range, make it a great choice for many applications.
