High efficiency

The LTC3826EG-1 is designed to achieve high efficiency over a wide range of operating conditions. It features a number of features that contribute to its high efficiency, such as:

A proprietary gate driver circuit that reduces switching losses A low-dropout mode that optimizes efficiency at light loads A programmable frequency range from 200kHz to 2.4MHz, which allows the user to choose the optimal frequency for efficiency and EMI performance The LTC3826EG-1 has been shown to achieve efficiencies of over 90% in typical applications. This makes it an ideal choice for applications where efficiency is a critical concern, such as battery-powered devices.

Low power consumption

The LTC3826EG-1 has a very low quiescent current of only 30uA. This makes it ideal for battery-powered applications, where every milliamp of current is precious.

Flexibility

The LTC3826EG-1 is a very flexible controller. It can be used to generate a single output voltage, or two independent output voltages. It can also be used in parallel to generate higher output currents.

When used to generate a single output voltage, the LTC3826EG-1 can be configured to operate in either phase-locked loop (PLL) mode or frequency-locked loop (FLL) mode. PLL mode provides the best output voltage regulation, while FLL mode provides the best line and load transient response.

When used to generate two independent output voltages, the LTC3826EG-1 can be configured to operate in either interleaved mode or independent mode. Interleaved mode reduces the input ripple current, while independent mode allows the two output voltages to be independently controlled.

Protection features

The LTC3826EG-1 includes a number of protection features, such as:

Overcurrent protection: The LTC3826EG-1 monitors the output current and will shut down the converter if the output current exceeds a preset limit. This helps to protect the converter and the load from damage. Thermal protection: The LTC3826EG-1 monitors its own temperature and will shut down the converter if the temperature exceeds a preset limit. This helps to prevent the converter from overheating and being damaged. Undervoltage lockout: The LTC3826EG-1 will not start up until the input voltage exceeds a preset threshold. This helps to prevent the converter from operating at too low of an input voltage, which could damage the converter or the load. Output overvoltage protection: The LTC3826EG-1 monitors the output voltage and will shut down the converter if the output voltage exceeds a preset limit. This helps to protect the load from being damaged by a high output voltage. The LTC3826EG-1 is a versatile and high-performance
