LTC3890MPGN-3#TRPBF

The LTC3890MPGN-3#TRPBF is an industry-leading DC/DC switching controller IC designed for both synchronous and asynchronous buck applications. This IC is part of the PMIC – Voltage Regulators – DC/DC Switching Controllers product family and provides precise voltage regulation,low standby power consumption, integrated power management, low noise, and precise current-limit protection, drive and protection for N-Channel MOSFETs.

The LTC3890MPGN-3#TRPBF is designed for applications ranging from 3V to 36V input voltage. Its integrated phase-lock loop allows for precise synchronization and phase management. This device has the capability of driving up to 18A of continuous output current and can be programmed with a Burst Mode operation to reduce output ripple current. This feature helps limit ripple current noise to ensure the reliability of the system over the long-term.

This device also includes integrated protection features such as undervoltage lockout, thermal shut down, and output current limit protection to protect against device damage and ensure desired performance. The LTC3890MPGN-3#TRPBF is ideal for applications such as telecom infrastructure, server/storage and computing systems, as well as LED lighting and motor control applications.

The LTC3890MPGN-3#TRPBF provides flexible voltage options by allowing the user to program their desired output voltage with an external resistor divider. Voltage regulation is provided by an internal error amplifier which continuously monitors the output voltage and adjusts the pulse width in order to maintain regulation.

The LTC3890MPGN-3#TRPBF also incorporates an internal low-dropout voltage regulator (LDO). This LDO is designed to allow the output voltage ripple to remain as low as 10mV at 24V input and 18A output. This ensures that the output voltage remains consistent over the entire operating range.

This device is also unique compared to other control ICs in the market because it can operate at frequencies up to 1MHz. It also features integrated soft-start and output overvoltage protection. The soft-start feature helps limit inrush current and output overvoltage protection prevents the output voltage from exceeding its specified limits, which helps to protect the system components in the event of a fault or overvoltage condition.

In summary, the LTC3890MPGN-3#TRPBF is an ideal choice for a wide range of applications where precise output voltage regulation and high efficiency are required. It is designed for both synchronous and asynchronous buck applications and its integrated protection features help to ensure safe and reliable operation.
