LT3741IFE-1#PBF

LT3741IFE-1#PBF is a high-performance high-efficiency DC DC switching controller which belongs to the PMIC (Power Management IC) voltage regulators and DC DC switching controllers. It offers wide input voltage range, high-output current and up to 98.5% power conversion efficiency. Moreover, the LT3741IFE-1#PBF also provides various protection features such as Over Temperature Protection (OTP), Overload Protection (OLP) and Short Circuit Protection (SCP).

The LT3741IFE-1#PBF is based on a buck-boost topology and it has two dual synchronization circuits to get synchronous rectification technology with accurate cycle-by-cycle current limit. It also has a digital logic controller, dual N-channel MOSFETs (Metal-Oxide-Semiconductor Field-Effect Transistor), wide-sensing current loop and two mode control features. The two mode control features are the pulse frequency modulation (PFM) and pulse width modulation (PWM) control.

The LT3741IFE-1#PBF provides three types of protection features to ensure the safety of the device and its user. The Over Temperature Protection feature can detect over temperature conditions and will immediately shut off the LT3741IFE-1#PBF. The Overload Protection feature can detect current overloads and will shut off the part before damaging the circuit components. The Short Circuit Protection feature will detect when the output current of the device is greater than the preset maximum limit and will shut off the output before any damage occurs to the device and the circuit.

In addition to the protection features, the LT3741IFE-1#PBF also has a wide selection of programmable protection and control settings. The independent Enable and Soft-Start/Soft-Stop pins allow for independent timing and sequencing of different power rail start-up and shut-down operations. The pins can also be configured for synchronization or multiple device paralleling for further cost savings.

The LT3741IFE-1#PBF is mainly designed for low voltage DC DC conversion applications such as automotive (distribution and controlling the power of electronic components), industrial (regulating and controlling power supply to electronic boards in machinery) and consumer electronics (providing supply voltage to digital displays, printers and other consumer based electronics). It also has a wide range of applications such as battery chargers and portable electronics, telecom equipment and handheld devices. The LT3741IFE-1#PBF is widely used due to its high efficiency and its low standby current (less than 100nA) that can provide longer life battery cycles for applications.

In summary, the LT3741IFE-1#PBF is a high-performance, high-efficiency DC DC switching controller from PMIC (Power Management IC) voltage regulators and DC DC switching controllers. It offers a wide input voltage range, accurate cycle-by-cycle current limit, a digital logic controller and two mode control features. It also provides multiple protection features such as Over Temperature Protection, Overload Protection and Short Circuit Protection for better safety of the device and its user. Moreover, it has a wide range of applications such as automotive, industrial, consumer electronics and telecommunication equipment.
