The MAX17595/MAX17596/MAX17597 is a family of peak-current-mode controllers which contain all the circuitry required for the design of wide input-voltage flyback and boost regulators. The MAX17595 offers optimized input rising and falling thresholds for universal input AC-DC converters and telecom DC-DC (36V–72V input range) power supplies. The MAX17596 offers input rising and falling thresholds suitable for low-voltage DC-DC applications (4.5V–36V input range). The MAX17597 offers all circuitry needed to implement a boost converter controller. All three controllers contain a built-in gate driver for external n-channel MOSFETs.
