The MAX5038A/MAX5041A also feature a clock input (CLKIN) for synchronization to an external clock, and a clock output (CLKOUT) with programmable phase delay (relative to CLKIN) for paralleling multiple phases. The MAX5038A/MAX5041A also limit the reverse current in case the bus voltage becomes higher than the regulated output voltage. The MAX5038A offers a variety of factory-trimmed preset output voltages (see Selector Guide) and the MAX5041A offers an adjustable output voltage between +1.0V to +3.3V.
