• Low ripple: less than 40mV for 3.3V output
• Integrated advanced protection functions (over current protection, current fold-back, auto recovery, over temperature protection)
• High efficiency: keeps heat to a minimum

Working Principle

The working principle of the XC9242B08CDR-G is simple. It works by switching the power supply input on and off at a high frequency, generating a "chopping" effect that is usually referred to as pulse width modulation (PWM). When the power supply is turned on, the input voltage is applied to the inductor, which increases the current in the coil. When the power supply is turned off, the stored energy in the inductor is passed on to the output of the regulator. Since the output voltage is maintained at a constant level, the output current is controlled by adjusting the width of the "on" and "off" cycle of the power supply.

Additionally, the XC9242B08CDR-G includes advanced protection functions to ensure the safety of connected components. The over-current protection feature is used to protect against over-current surges, and the current fold-back feature helps protect against excessive levels of current. The auto-recover function automatically resets the system after a fault condition, preventing possible damage to connected components. Finally, the over-temperature protection feature prevents the regulator from overheating when continuously driving a heavy load.
