The is a 8-channel parallelable 1A Buck DC/DC Converter with digitally programmable high efficiency multioutput power supply. This DC/DC IC consists of eight synchronous buck converters IOUT up to 1A each all powered from independent 2.25 to 5.5V input supplies. 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.
