The LTC3633EUFD#PBF is a dual, 3A, 15Vin, monolithic synchronous step-down switching voltage regulator manufactured by Analog Devices. It features a 4MHz switching frequency and can operate from input voltages ranging from 4V to 15V. It also features a low ripple Burst Mode operation for improved efficiency, output over-current protection, and low-noise fixed frequency operation (3.5mV peak-to-peak output ripple ). The LTC3633EUFD#PBF is fully EMI compliant, making it ideal for power-sensitive and space-constrained applications in the industrial, automotive, computing, communication, and consumer markets.
