Working Principle

The LT8608HMSE#TRPBF provides a current regulated output and features a wide input voltage range. The regulator is enabled by the EN pin, and the output voltage is regulated via the feedback voltage on the FB pin. The regulator uses the PWM modulator technique to regulate the output voltage. The internal blocks in the LT8608HMSE#TRPBF include an oscillator, a PWM modulator, an error amplifier, a comparator, and a driver circuit. The pulse width modulation (PWM) regulation is used to achieve an accurate output voltage despite variations in the input voltage. The oscillator produces a triangular waveform, and the comparator compares the feedback voltage with the triangle wave. If the feedback voltage is higher than the triangle wave, the output of the comparator will be high, and the driver circuit will turn off the power switch. The feedback voltage is regulated by adjusting the duty cycle of the PWM. This provides a stable output voltage as variations in the input voltage occur.

Conclusion

The LT8608HMSE#TRPBF is a high efficiency, wide input range buck-boost regulator controller. It operates in perfect buck, perfect boost and buck-boost modes, and is suitable for applications requiring wide input voltage range, high efficiency, and high current output. The LT8608HSME#TRPBF utilizes the PWM modulator technique to ensure a stable output voltage despite variations in the input voltage. It is widely used in battery powered systems, solar energy systems, unpowered or mains powered systems, communication equipment, and embedded systems.
