The working principle of the LTC1709EG-85#PBF is simple, yet highly effective. The device uses pulse width modulation (PWM) to control the output voltage of the controller. At its core, the device monitors the input voltage and compares it to the desired output voltage in order to adjust the duty cycle of the pulse width modulation pulses. When the input voltage is greater than the desired output voltage, the duty cycle of the PWM is decreased, resulting in a regulated output voltage. Conversely, when the input voltage is lower than the desired output voltage, the duty cycle is increased, resulting in a regulated output voltage. The device is designed to be very efficient and the circuit is designed to minimize the heat generated.

The LTC1709EG-85#PBF is an ideal choice for applications which require a reliable, efficient, and accurate power supply. From sensor applications, consumer electronics, and automotive designs to industrial automation applications, the device can provide an excellent performance.
