в–  DESCRIPTIO The LTC В®1698 is a precision secondary-side forward
converter controller that synchronously drives external
N-channel MOSFETs. It is designed for use with the
LTВ®3781 primary-side synchronous forward converter
controller to create a completely isolated power supply.
The LT3781 synchronizes the LTC1698 through a small
pulse transformer and the LTC1698 drives a feedback
optocoupler to close the feedback loop. Output accuracy
of В±0.8% and high efficiency over a wide range of load
currents are obtained. High Efficiency Over Wide Load Current Range …
