onsemi NCP1580
The NCP1580 is a voltage mode PWM controller designed to operate from a 5.0 V or 12 V supply and produce an output voltage as low as 0.8 V. This 8−pin device provides an optimal level of integration to reduce size and cost of the power supply. The NCP1580 has a fixed 350 kHz oscillator and soft−start function.- Min Voltage : 4.5V
- Max Voltage : 13.2V
- Max Operating Temp : 85°C
- Min Operating Temp : -40°C
