The LTC3831EGN-1#TRPBF is a Voltage Mode Step-Up Controller with Integrated FETs from Analog Devices. This integrated step-up, or boost, converter is designed to efficiently produce a higher output voltage from a lower input voltage, such as extended battery life for mobile applications. The part can be configured for a variety of topologies using either a single inductor or a Flyback controller. It features automatic synchronization to an external clock, allowing for accurate current sharing in multiple inductor applications, as well as an adjustable frequency range from 125 kHz to 2.2 MHz. Its integrated MOSFETs and PWM control circuitry in a single package, combined with its small size, low-profile, and low-part-count make it an ideal choice for a variety of space-constrained applications. Other features of the LTC3831EGN-1#TRPBF include adjustable switching frequency, under-voltage lockout, short-circuit and over-temperature protections, and adjustable constant-frequency current mode control with cycle-by-cycle current limit.
