LM2574N-12/NOPB

Понижающий импульсный стабилизатор, фиксированный, 4В-40В (Vin), 12В и 0.5A на выходе, DIP-8.

The LM2574N-12/NOPB is a SIMPLE SWITCHER step down (buck) voltage regulator with fixed output in 8 pin DIP package. It provides all active functions required for step down (buck) switching regulator. This simple to use regulator includes internal frequency compensation and fixed frequency oscillator. The LM2574 offers high efficiency replacement for popular three terminal linear regulators. It substantially reduces size of heat sink and in many cases, heat sink is not required. A standard series of inductors optimized for use with LM2574 are available from several different manufacturers. This feature greatly simplifies the design of switch mode power supplies. This regulator also includes specified ±4% tolerance on output voltage within specified input voltages and output load conditions and ±10% on oscillator frequency. External shutdown function features 50µA (typical) standby current.
