The MAX5037 also features 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 MAX5037 operates over the extended industrial temperature range (-40C to +85C) and is available in 44-pin MQFP or thin QFN packages. Refer to the MAX5038/MAX5041 data sheet for either a fixed output voltage controller or an adjustable output voltage controller in a 28-pin SSOP package.
