AF2576 Datasheet | Alfa-MOS

Description The AF2576 series of regulators are monolithic integrated circuits that provide all the active functions for a step-down (buck) switching regulator, capable of driving 3A load with excellent line and load regulation. These devices are available in fixed output voltages of 3.3V, 5V, 12V, 15V and adjustable output versions. Requiring a minimum number of external ponents, these regulators are simple to use and include internal frequency pensation and a fixed-frequency oscillator. The AF2576 series offers a high-efficiency replacement for popular three-terminal linear regulators. It substantially reduces the size of the heat sink, and in some cases no heat sink is required. A standard series of inductors optimized for use with the AF2576 is available from several different manufacturers. This feature greatly simplifies the design of switch-mode power supplies. Other features include a...
