LT8602IUJ#PBF

LT8602 is a quad channel, current mode, monolithic buck switching regulator with a programmable power-on reset. This device can be configured for micropower Burst Mode operation or pulse-skipping operation at light load. The high voltage channels are synchronous buck regulators that operate from an input of 3V to 42V. Internal synchronous power switches provide high efficiency with output currents upto 1.8A. This device uses a 2-phase clock with channels 1 and 3 operating 180° from channels 2 and 4 to reduce input ripple current on both HV and LV inputs. All channels have cycle-by-cycle current limit, providing protection against shorted outputs. Thermal shutdown provides additional protection. It is widely used in application such as automotive systems, distributed supply regulation, industrial controls and power supplies.
