Flyback regulator simplifies design, eliminates optocoupler
2/24/2011 8:31 AM EST
Linear Technology Corp. announced the LT3512, a high voltage isolated monolithic flyback regulator that simplifies the design of an isolated DC/DC converter.
No optocoupler, third winding or signal transformer is required for feedback since the output voltage is sensed from the primary-side flyback signal. The LT3512 operates over a 4.5V to 100V input voltage range, has a 420mA, 150V power switch and delivers up to 4.5 watts of output power, making it well suited for a wide variety of telecom, datacom, automotive, industrial and medical applications.
