LTC3402EMS#PBF application field and working principle

LTC3402EMS#PBF is a DC to DC switching regulator included in the PMIC (Power Management IC) family of voltage regulators. The regulator is designed specifically for audio applications, such as in vacuum tube amplifiers, portable electronic devices, cellular phones, digital radios, or audio power amplifiers. It can provide a regulated output voltage of up to 12V and up to 1A of output current.

The LTC3402EMS#PBF DC to DC switching regulator is a resonant converter which works in two stages: the first stage is the power switch which turns the power on, and the second stage is the resonant inductor which converts the power from DC to AC, and finally from AC to the required output voltage.

The power switch is an N-MOSFET transistor, driven by a control signal from an oscillator. The oscillator frequency is determined by an external resistor and capacitor connected to the control pin. The voltage output is determined by an adjustable voltage divider connected to the oscillator.

The resonant inductor allows the power to be switched quickly and efficiently and also helps to reduce the amount of switching losses. It is constructed by winding two coils of wire around a core material. The current flows through the coils in opposite directions, providing the resonant energy needed to increase the voltage conversion efficiency.

The LTC3402EMS#PBF can be used to regulate a variety of switching DC to DC converters, including DC to AC (buck converters), AC to DC (boost converters), and step-up/step-down converters. It is an excellent choice for applications where efficiency and power efficiency are of high priority. The device can also be configured to provide a wide range of output voltage ranges, allowing it to meet the needs of a variety of applications.

Overall, the LTC3402EMS#PBF is a highly efficient and reliable DC to DC switching regulator, ideal for a variety of audio and other electroni applications. It is designed to provide a wide range of output voltage and current ratings while maintaining high switching efficiency.
