The LTC3787IUFD#TRPBF is an adjustable synchronous step-down DC-DC controller with integrated MOSFETs from Analog Devices. It offers an input voltage range of 4.5-40V, a selectable frequency range of 150kHz to 2MHz, accurate current-mode control and an integrated high-side and a low-side MOSFETs. It's fully protected against current limit, over-temperature, under-voltage lockout and short circuit protection and features a 0.025% low-voltage reference, 0.5% over-voltage lockout accuracy and 1.5% current sense accuracy. It features open circuit soft-start and fast transient response, and is suitable for numerous industrial, audio, computing and networking applications.
