All circuits of this series are capable of driving a 3.0 A load with excellent line and load regulation. These devices are available in fixed output voltages of 3.3 V, 5.0 V, 12 V, 15 V, and an adjustable output version. These regulators were designed to minimize the number of external components to simplify the power supply design. Standard series of inductors optimized for use with the CBM2576 are offered by several different inductor manufacturers. Since the CBM2576 converter is a switch–mode power supply, its efficiency is significantly higher in comparison with popular three–terminal linear regulators, especially with higher input voltages. In many cases, the power dissipated is so low that no heatsink is required or its size could be reduced dramatically. A standard series of inductors optimized for use with the CBM2576 are available from several different manufacturers. This feature greatly simplifies the design of switch–mode power supplies. The CBM2576 features include a guaranteed ±4% tolerance on output voltage within FOCUS ON DEVELOPMENT • SINCERELY SERVICE • INNOVATIVE FUTURE www.c oreba i. com  PDF
