36V 10W No-Opto Isolated
Flyback Converter
FEATURES DESCRIPTION 4V to 36V Input Voltage Range
nn 3.6A, 65V Internal DMOS Power Switch
nn Low Quiescent Current
nn Quasi-Resonant Boundary Mode Operation at
Heavy Load
nn Low Ripple Burst Mode® Operation at Light Load
nn Minimum Load < 0.5% (Typ) of Full Output
nn No Transformer Third Winding or Opto-Isolator
Required for Output Voltage Regulation
nn Accurate EN/UVLO Threshold and Hysteresis
nn Temperature Compensation for Output Diode
nn Output Short-Circuit Protection
nn Thermally Enhanced 8-Lead SO Package The LT®3002 is a monolithic micropower isolated flyback converter. By sampling the isolated output voltage
directly from the primary-side flyback waveform, the part
requires no third winding or opto-isolator for regulation.
The output voltage is programmed with two external
resistors and a third optional temperature compensation
resistor. Boundary mode operation provides a small magnetic solution with excellent load regulation. Low ripple
Burst Mode operation maintains high efficiency at light
load while minimizing the output voltage ripple. A 3.6A, …
