Switching regulators is available in different circuit configurations including turnaround time, feed-forward, push-pull, and not iso lated a single terminal or one polarity types. In addition, switching regulators can operate in three modes - down, step-up or reverse polarity.

M 2575 a series developed by National Semiconductor regulators are monolithic IC that provide active functions to step down (again) change the regulator can handle the load A1A, with excellent line and load regulation. These devices are available in fixed output voltages of 3.3V, 5V, 12V, 15V and adjustable output version.

Requiring a minimum number of external components, these regulators are simple to use and include internal frequency compensation and a fixed frequency oscillator. LM 2575 series offers high-performance replacement for popular 3 terminal linear regulators. Substantially reduced the size of the heatsink, and in many cases no heat sink is required. Version sets the output voltage is illustrated in Fig.

The National Semiconductor LM 2577 1577/LM are monolithic integrated circuits that provide all the functions of power and control of step-up (boost), fly backward, forward and converter switching regulators. The device is available in three different output voltage: 12 V, 15 V and adjustable.
