The Working Principle of LT1765ES8#TRPBF

The LT1765ES8#TRPBF is a switching regulator featuring an internal power MOSFET, which is controlled by an adjustable frequency oscillator, operating at up to 600KHz. An internal comparator, PWM comparator and error amplifier are used to regulate the output voltage.The PWM comparator modulates the duty cycle of the oscillator based on the error voltage from the error amplifier. The duty cycle corresponds to the current level in the output inductor, controlled by the power MOSFET. When the power MOSFET turns on, the inductor will be charged, and when the MOSFET turns off, the stored charge will be delivered to the output, thus providing the regulated voltage.The advantage of the LT1765ES8#TRPBF\'s switching regulator approach is its extremely high efficiency, low noise level and high frequency. Moreover, these regulators do not require any external compensation and provide excellent line and load regulation, making them the perfect choice for high current power electronics applications.
