LT8714EFE#PBF is a DC-DC step-down power supply controller IC that is designed by Linear Technology. It is categorized under the PMIC (Power Management IC) family and is also classified under Voltage Regulators and DC DC Switching Controllers. The LT8714EFE#PBF is composed of high efficiency MOSFET switches, voltage-mode constant frequency current-mode peak current mode control, and a high level of over-current and short-circuit protection. It features a simple resistor divider and TL431 reference that allows it to maintain the voltage of the output voltage within the specified range. It also supports various modes such as current mode control, programmable soft-start, and cycle-by-cycle current fold-back protection.

The application fields for the LT8714EFE#PBF are rather extensive. It can be used for various applications such as portable device chargers, automotive charging systems, industrial and consumer power supplies, and other applications that require high voltage and highly efficient DC-DC power conversion. The device also features a shutdown mode that allows it to be placed in a state of low current consumption or completely turned off when not in use.

The LT8714EFE#PBF is designed to work with an input range of 4.5V to 40V and an output range of 0.9V to 30V, with a maximum loads of 6A and a maximum switching frequency of 500kHz. It is capable of providing continuous power up to 100W of power with an extremely high efficiency rating. It also has a wide dynamic range for soft start by setting an internal capacitor with a soft start range from 10µs to 500ms. The device also offers various protection features such as thermal shutdown, reversed battery protection, undervoltage lockout, and fault flag output.
