LT8316 560V Micropower No-Opto IN Isolated Flyback Controller FEATURES DESCRIPTION n Wide Input Voltage Range: 16V to 560V (600V max) The LT 8316 is a micropower, high voltage flyback con- n No Opto-Isolator Required for Regulation troller. No opto-isolator is needed for regulation. The n Quasi-Resonant Boundary Mode Operation device samples the output voltage from the isolated fly- n Constant-Current and Constant-Voltage Regulation back waveform appearing across a third winding on the n Low-Ripple Light Load Burst Mode Operation transformer. Quasi-resonant boundary mode operation n Low Quiescent Current: 75A improves load regulation, reduces transformer size, and n Programmable Current Limit and Soft-Start maintains high efficiency. n TSSOP Package with High-Voltage Spacing At start-up, the LT8316 charges its INTV capacitor via CC n AEC-Q100 Qualification in Progress a high voltage current source. During normal operation, the current source turns off and the device draws its power from a third winding on the transformer minimiz- APPLICATIONS ing standby power dissipation. n Isolated Telecom, Automotive, Industrial, Medical The LT8316 operates from a wide range of input supply Power Supplies voltages and can deliver up to 100W of power. It is avail- n Isolated Off-Line Housekeeping Power Supplies able in a thermally enhanced 20-pin TSSOP package with n Electric Vehicles and Battery Stacks four pins removed for high-voltage spacing. n Multioutput Isolated Power Supplies for Inverter Gate All registered trademarks and trademarks are the property of their respective owners.
