The LTC3867IUF#TRPBF is a current mode synchronous step-down switching regulator controller manufactured by Analog Devices. It drives N-channel power MOSFET stages and utilizes a nonlinear control architecture to minimize output voltage transient excursions.
This controller supports a wide input voltage range of 4V to 38V and can regulate output voltages from 0.6V up to 14V. It features a precision 0.6V reference with ±0.75% accuracy. The operating frequency is programmable from 200kHz to 1.2MHz, with support for PLL frequency synchronization.
The LTC3867IUF#TRPBF offers flexibility in current sensing, allowing the use of either a discrete sense resistor or the inductor's DCR. It includes programmable DCR temperature compensation for a constant current limit regardless of inductor temperature and programmable inductor temperature-based thermal shutdown for component protection. Soft recovery from output shorts or overcurrent is also supported.
Packaged in a 24-lead QFN (4x4mm) with a surface mount type, this controller is suitable for applications requiring efficient power management. It supports various operating modes including Burst Mode, continuous, and pulse-skipping modes.
