LT8316
600VIN Micropower No-Opto
Isolated Flyback Controller
FEATURES DESCRIPTION Wide Input Voltage Range: 16V to 600V
nn No Opto-Isolator Required for Regulation
nn Quasi-Resonant Boundary Mode Operation
nn Constant-Current and Constant-Voltage Regulation
nn Low-Ripple Light Load Burst Mode® Operation
nn Low Quiescent Current: 75μA
nn Programmable Current Limit and Soft-Start
nn TSSOP Package with High-Voltage Spacing The LT®8316 is a micropower, high voltage flyback controller. No opto-isolator is needed for regulation. The
device samples the output voltage from the isolated flyback waveform appearing across a third winding on the
transformer. Quasi-resonant boundary mode operation
improves load regulation, reduces transformer size, and
maintains high efficiency. nn APPLICATIONS
Isolated Telecom, Automotive, Industrial, Medical
Power Supplies
nn Isolated Off-Line Housekeeping Power Supplies
nn Electric Vehicles and Battery Stacks
nn Multioutput Isolated Power Supplies for Inverter Gate
Drives
nn At start-up, the LT8316 charges its INTVCC capacitor via
a high voltage current source. During normal operation, …
