It is optimized for powering low power FPGAs, DSPs, and microprocessors from 5V inputs. Four synchronous step down buck regulators range from 1.5A system power to 4A core power. All outputs support ±10% margining and the two highest power outputs support dynamic voltage control to support processors that can utilize this function to save power. Through a 400KHz I²C interface, the customer can monitor an input voltage flag and PGOOD flags for each output. The I²C port can also be used to modify power up and down sequencing options, assign PGOOD outputs to the PGOOD pins, enable outputs and select switching frequency. High switching frequency and a current mode architecture with internal compensation enable a very fast transient response to line and load changes without sacrificing stability and keeping board space to a minimum. Application includes low power processor, ASIC and FPGA power, industrial control, test equipment, POS terminals. • Input voltage range from 4.0V to 5.5V• 4 synchronous buck regulators, internally compensated current mode• 1MHz to 2.1MHz switching frequency range• 100mA LDO 1.5V to 3.6V, 20mV step• ±2% maximum total dc output error over line, load and temperature• Dynamic voltage scaling, status monitoring by channel• Sequencing control, input voltage status register• Highly flexible conditional sequencing engine with external input• 2 configurable PGOOD outputs, adjustable switching frequency• 32-pin QFN package, operating temperature range from -40°C <= TJ <= 125°C
