The LTC3859AEUHFPBF is an integrated circuit from Analog Devices. It is a dual buck controller with two independent, synchronous step-down DC/DC controllers. It has a wide input voltage range of 4.5V to 60V, up to 7.5A maximum output current, and can produce an output voltage as low as 0.6V. It features a wide operating temperature range of -40°C to 150°C, fast transient response time, and a current mode pulse-width modulation (PWM) control scheme with frequency foldback. It also has an onboard programmable soft-start time, adjustable under voltage lockout, input voltage feed forward, and power good output. This IC is available in a thermally enhanced 8-pin package.
