Working principle

The CHL8225-00CRT utilizes an optimized buck-boost converter to regulate the output voltage. This converter uses Pulse Width Modulation (PWM) to control the output voltage. The output voltage is measured using an internal voltage divider and monitored by the internal PWM Controller. The device then adjusts the PWM duty cycle to maintain a constant output voltage.The device also features cycle by cycle current limiting in order to protect against overload conditions. It can deliver an adjustable output current of up to 1A. The device also has an enable pin that can be used to control the output voltage. The device also includes a low-dropout regulator that provides protection from high voltage transients.

Conclusion

The CHL8225-00CRT is a power management solution that offers efficient and precise control of output voltage for electronics applications. It offers many advantages such as a low input current, low power consumption, cycle-by-cycle current limiting, adjustable output current capability and low-dropout protection. This device is ideal for use in IoT, mobile phone and tablet applications, as well as automotive, medical, and consumer electronics applications.
