Description
The LT®8602 is a quad channel, current mode, monolithicbuck switching regulator with a programmable power-onreset. All regulators are synchronized to a single oscillatorwith an adjustable frequency from 250kHz to 2.2MHz. TheLT8602 can be configured for micropower Burst Modeoperation or pulse-skipping operation at light load. Micropoweroperation results in quiescent current of 30μAwith all four regulators operating in the application below.The high voltage channels are synchronous buck regulatorsthat operate from an input of 3V to 42V. The outputcurrents are up to 1.5A (OUT1) and 2.5A (OUT2). Thelow voltage channels operate from an input of 2.6V to5.5V. Internal synchronous power switches provide highefficiency with output currents up to 1.8A. The LT8602uses a 2-phase clock with channels 1 and 3 operating 180°from channels 2 and 4 to reduce input ripple current onboth HV and LV inputs. All channels have cycle-by-cyclecurrent limit, providing protection against shorted outputs.Thermal shutdown provides additional protection.The LT8602 is available in a 40-lead 6mm × 6mm QFNpackage.
