The LTC3878EGN#TRPBF is an integrated circuit (IC) component manufactured by Linear Technology (now part of Analog Devices Inc.). It is a high-performance synchronous step-down DC/DC controller.
One of the key features of the LTC3878EGN#TRPBF is its wide input voltage range, which allows it to operate with input voltages from 4.5V to 38V. This feature makes it suitable for a wide range of applications in various industries. Additionally, it offers an adjustable output voltage from 0.8V to 5.5V, providing flexibility in power supply designs.
The IC utilizes a constant frequency current mode architecture with a high switching frequency of up to 1MHz, allowing for small external components to be used. This feature helps in reducing the overall solution size and cost.
Another important highlight of the LTC3878EGN#TRPBF is its excellent transient response and line/load regulation, ensuring stable and reliable power supply to the load even under varying operating conditions. It also features a current sense amplifier with an adjustable threshold, facilitating accurate current limit protection.
The IC incorporates a phase lock loop (PLL) frequency synchronization capability. This enables synchronization with an external clock, thus facilitating easy parallel operation of multiple LTC3878EGN#TRPBF controllers. Additionally, it offers a clock output function, which can drive other controllers or provide a synchronized clock signal to other components
