Low Power Isolated Monolithic Flyback Switching Regulator
Linear Technology announced the LT3574, an isolated monolithic flyback switching regulator that significantly simplifies the design of a low power isolated DC/DC converter. No opto-isolator, third winding or signal transformer is required for feedback since the output voltage is sensed from the primary-side flyback signal. The LT3574 operates over a 3V to 40V input voltage range, has a 0.65A NPN power switch and can deliver up to 3 watts of output power, making it well suited for a wide variety of industrial, medical, telecom, datacom and automotive applications.
The Additional features include an onboard low dropout regulator for IC power, programmable soft start, undervoltage lockout, adjustable current limit and output voltage temperature compensation.
