The LTC3867 is a fixed frequency synchronous step-down DC/DC controller with nonlinear control, differential output voltage sensing and clock synchronization. Nonlinear control minimizes the output voltage excursion during load transient events by increasing the operating frequency, allowing the LTC3867 to recover from a large load step in only a few cycles. This feature reduces the maximum deviation from nominal by up to 50% compared to traditional controllers. The LTC3867’s 4V to 38V input range encompasses a wide variety of applications including most intermediate bus voltages. Strong onboard N-channel MOSFET gate drivers allow the use of high power external MOSFETs for high load current, up to 25A. The output voltage range is 0.6V to 14V making it ideal for powering higher voltage devices.
