Product Overview

The LT8315IFE#PBF from Linear Technology is a 560VIN micropower no-opto isolated flyback converter with 630V/300mA switch in 20 pin TSSOP package. The device samples the output voltage from 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. At start-up, the LT8315 charges its INTVCC capacitor via a current source attached to the DRAIN pin. During normal operation current source turns off and the device draws its power from a third winding on the transformer. It is used in isolated auxiliary/housekeeping power supplies, electric vehicles and battery stacks.
  • Wide input voltage range from 18V to 560V, deliver up to 15W of power
  • Constant-current and constant-voltage regulation
  • Low ripple light, load burst mode operation
  • Low quiescent current is 70μA
  • Programmable current limit and soft start
  • Operating temperature range from -40°C to 125°C
  • Switching frequency of 140KHz
  • Chip bias voltage supply range from 9.5V to 40V
  • Maximum FB regulation voltage of 1.25V

Applications

Automotive, Industrial, Power Management, Communications & Networking
