DESCRIPTION
The LT®1725 is a monolithic switching regulator controller specifically designed for the isolated flyback topology. It drives the gate of an external MOSFET and is generally powered from a third transformer winding. These features allow for an application input voltage limited only by external power path components. The third transformer winding also provides output voltage feedback information, such that an optoisolator is not required. Its gate drive capability coupled with a suitable external MOSFET can deliver load power up to tens of watts.
FEATURES
■ Drives External Power MOSFET with External ISENSE Resistor
■ Application Input Voltage Limited Only by External Power Components
■ Senses Output Voltage Directly from Primary Side Winding—No Optoisolator
Required
■ Accurate Regulation Without User Trims
■ Regulation Maintained Well into Discontinuous Mode
■ Switching Frequency from 50kHz to 250kHz with External Capacitor
■ Optional Load Compensation
■ Optional Undervoltage Lockout
■ Available in 16-Pin SO and SSOP Packages
APPLICATIONS
■ Telecom Isolated Converters
■ Offline Isolated Power Supplies
■ Instrumentation Power Supplies
