The LTC3412AEFE#PBF is a Switching Voltage Regulators 3A, 4MHz, Monolithic Synch Step-Down IC manufactured by Analog Devices. It is designed to operate from an input voltage range of 2.7V to 5.5V and provides a fixed output voltage of 3.3V. It can operate with current output of up to 3A over its full rated temperature range. It is ideal for powering processor core supplies, memory and peripherals. The LTC3412AEFE#PBF has an adjustable soft-start circuitry, which allows for a controlled and gradual rise in output voltage when the controller is initially powered up. Its internal, high-efficiency, 4MHz synchronous buck switching converters feature a high bandwidth, tightly regulated output voltage, and current mode control for excellent line, load and temperature stability. It also has a synchronous rectifier for improved efficiency and fast transient response.
