Product Summary

The MAX641AESA is a step-up switching regulator. It is designed for minimum component DC-DC converter circuits in the 5mW to 10W range. Low-power applications require only an output filter capacitor and a small, low-cost inductor. The MAX641AESA is preset for +5V, +12V and +15V outputs, respectively. The applications of the MAX641AESA include: (1)Simple, high-efficiency DC-DC converters; (2)Uninterruptible board-level power supplies; (3)Power conditioning for battery systems; (4)Portable instruments and commumications.
