Maxim Integrated MAX5014
The MAX5014 allows 85% operating duty cycle and could be used to implement flyback converters, whereas the MAX5015 limits the operating duty cycle to less than 50% and can be used in single-ended forward converters. The switching frequency is internally trimmed to 275kHz ±10%, thus reducing magnetics and filter component costs. The MAX5014/MAX5015 are available in 8-pin SO packages.| Part No. | MAX5014 |

GENERAL DESCRIPTION
The MAX5014/MAX5015 integrate all the building blocks necessary for implementing DC-DC fixed-frequency isolated power supplies. These devices are current-mode controllers with an integrated high-voltage startup circuit suitable for isolated telecom/industrial voltage range power supplies. Current-mode control with leading-edge blanking simplifies control-loop design and internal ramp compensation circuitry stabilizes the current loop when operating at duty cycles above 50% (MAX5014). A high-voltage startup circuit allows these devices to draw power directly from the 18V to 110V input supply during startup. An evaluation kit (MAX5015EVKIT) is also available. Warning: The MAX5014/MAX5015 are designed to operate with high voltages. Exercise caution.APPLICATIONS
