Linear Technology recently announced H-grade versions of the LT8304/-1 monolithic flyback regulators with guaranteed operation for junction temperatures as high as 150°C. By sampling the isolated output voltage directly from the primary-side flyback waveform, it requires no opto-coupler or third winding for regulation.
The LT8304H/-1’s features, specs, and benefits:
VIN Range from 3 to 100 V
Up to 24 W of output power
LT8304-1 Capable of output voltages up to 1 kV
Onboard 2-A, 150-V integrated DMOS power switch
Off-the-shelf power transformers
No opto-coupler or transformer third winding required for voltage feedback
116-µA Quiescent current
Boundary mode operation
Accurate input enable & undervoltage lockout with hysteresis
Output diode temperature compensation
H Grades: –40°C to 150°C operating junction temperatureLinear Technology | www.linear.com
