CHL8228G-09CRT

CHL8228G-09CRT is a kind of special purpose voltage regulator. It can be used in a variety of applications, from consumer electronics to automotive, from communications to healthcare, from heavy industrial markets to power supplies, to fulfill your needs for voltage in a low-voltage circuit.

The CHL8228G-09CRT uses step down switching regulators that employs synchronous rectification in the output stage to provide superior efficiency with high current density. Thanks to the wide input and output voltage range and the wide operating temperature range, and the adjustable soft start, it can provide stable power delivery with low noise and current ripple, regardless of the input voltage conditions.

The CHL8228G-09CRT has a flexible integrated power stage with a 4FETs (Field Effect Transistor) topology, allowing the device to provide up to 3A of continuous output current. It also integrates a high power density gate driver with dead time protection, which can operate at up to 20MHz switching frequency and achieve over 95% of efficiency.

The working principle of CHL8228G-09CRT is based on pulse width modulation (PWM) control. The chip first detects the input voltage and converts the voltage into digital data. Then the digital data is compared with the preset PWM parameters in the device, and calculates the duty cycle of the output.

Finally, an output signal will be generated to control the on-time of the power switch and generate an output voltage that is both regulated and stable. It is important to note that the output voltage is conversion tracking the input, which allows an output voltage that is tolerant to input transients, giving the user extra protection against overvoltage or short circuit.

In conclusion, The CHL8228G-09CRT is a special purpose voltage regulator which offers a wide range of functionality with multiple integrated features. It is available in the form of power module, and is well-suited for high power applications.
