Workinig Principle of SP6660EN-L

SP6660EN-L utilizes a Pulse Frequency Modulation (PFM) control technique which enables the device to maintain a high conversion efficiency across a wide input voltage range. The chip includes a power field-effect transistor and control circuit. The output voltage is regulated by comparing two PWM signals generated internally. The higher PWM signal is set by the reference voltage and feedback loop, and the lower PWM signal is set by the reference current flowing from the load. Once the load current decreases, the lower PWM is lowered and the voltage error amplifiers increase the duty cycle of the switching transistor to compensate, thus maintaining a stable output voltage.

The chip is further equipped with a low dropout (LDO) regulator, which senses the output voltage of the main DC-DC converter, and provides additional voltage regulation below the specified output range. This circuits helps to reduce the ripple and noise in the system and ensure a more precise output voltage.

To further enhance the performance and reliability of SP6660EN-L, it includes a number of protection features. These include over-temperature shutdown, output disconnect, under-voltage lockout, over-voltage protection and programmable reset function.
