The LTC3728LXCUH is a dual, 550kHz, 2-phase synchronous switching regulator controller designed by Linear Technology. This device features dual N-channel MOSFET synchronous drive and supports a wide input voltage range from 4.5V to 28V, with output voltages adjustable from 0.8V to 7V. It offers a high switching frequency of 550kHz, which can be phase-locked between 250kHz and 500kHz, reducing input capacitance and power supply noise.
Key features include OPTI-LOOP® compensation for minimizing output capacitance, power good output voltage indicator, and adjustable soft-start current ramping. The controller also provides foldback output current limiting and latched short-circuit shutdown. It operates with very low dropout, achieving 99% duty cycle.
