LTC3375EUK#PBF

LTC3375 is a digitally programmable high efficiency multioutput power supply IC. DC/DC enables, output voltages, operating modes, and phasing may all be independently programmed over I²C or used in standalone mode via simple I/O with power-up defaults. The DC/DCs may be used independently or in parallel to achieve higher output currents of up to 4A per output with a shared inductor. Alarm levels for high die temperature may also be programmed via I²C with a maskable IRQ output for monitoring DC/DC and system faults. Pushbutton ON/OFF/RESET control, power-on reset, and a watchdog timer provide flexible and reliable power-up sequencing and system monitoring. It is widely used in application such as general purpose multichannel power supplies, industrial/automotive/communications etc.
