LTC3836EGN is a highly efficient DC-DC controller, which belongs to PMIC (Power Management Interface Circuits) Voltage Regulators - DC-DC Switching Controllers. It is a highly integrated and sophisticated application field of derivatives built on Linear Technology’s proprietary high efficiency design. It can be used in various applications, including desktop PCs, notebooks, digital cameras, and other systems that need efficient power conversion.

The LTC3836EGN controller consists of a power MOSFET gate drive, a high frequency resonant gate driver, and various integrated analog circuitry. This integrated circuitry can be divided into three main blocks. The first block is a high frequency buck converter that provides an adjustable output voltage by varying its inductor current. This block also contains a “slope compensation” circuit that helps the output voltage stay more stable when the inductor current is changing. The second block is an oscillator and reference current generator, which are used to provide the pulse-width modulation (PWM) drive. The third block is an over-current protection circuit which will shut down the system when an overload occurs.

The LTC3836EGN can provide up to 95% power conversion efficiency in its highest switching frequency. The integrated oscillator and reference current generator enable to adjust the frequency of PWM pulses and thus the ripple of the output voltage. For example, increasing the frequency can reduce ripple of the output voltage. The integrated current protection circuit provides protection against over-current or short-circuit conditions, eliminating the need for external components. The LTC3836EGN also has various integrated functions, such as power good, soft-start, under-voltage lockout, and frequency jittering, all of which can be utilized to tailor the system for specific applications.

The LTC3836EGN is a highly integrated and efficient DC-DC controller which can be used in various applications requiring multiple voltage rails with high precision. It is suitable for applications such as desktop PCs, notebooks, digital cameras, and other systems needing efficient, advanced power conversion. The integration of the PWM oscillator, current protection, and other features provide versatile and reliable operation of the LTC3836EGN, making it a great choice for many different applications.
