The Analog Devices LTC3854IDDB#TRPBF is a dual high-current, high-efficiency asynchronous buck controller with integrated FET drivers. It features programmable current mode control, dynamic voltage positioning, peak current-mode regulation, adjustable soft-start, and adjustable current limit. It uses thermal feedback to generate a low-jitter clock source to eliminate loop instability, and integrated P-channel MOSFETs and N-channel MOSFETs offer high efficiency, small size, and low component count. The integrated FET drivers allow for high-frequency, low-EMI operation of the buck converter for up to 2MHz switching. The LTC3854IDDB provides up to 4A of output current and can operate from inputs of 2.5V to 5.5V.
