Introduction

AI Translation

200kHz maximum switching frequency to achieve high power density. Performance at switching frequencies above 100kHz may be degraded due to internal timing constraints associated with fully isolated flyback mode. Included are the oscillator, control, and protection circuitry such as current limit and overvoltage lockout. Switch frequency and maximum duty cycle are adjustable. Bootstrap circuitry draws 200μA for start-up of isolated topologies. A 5V reference as well as a 15\ gate bias are available to power external primary-side circuitry. No external current sense resistor is necessary with LT1103 because it is integrated with the high current switch. The LT1105 brings out the input to the current limit amplifier and requires the use of an external sense resistor. The LT1103/LT1105 have unique features not found on other offline switching regulators. Adaptive antisat switch drive allows wide ranging load currents while maintaining high efficiency. The external FET is protected from insufficient or excessive gate drive voltage with a drive detection circuit. An externally activated shutdown mode reduces total supply current to less than 200μA, typical for standby operation. Fully isolated and regulated outputs can be generated in the optional isolated flyback mode without the need for optocouplers or other isolated feedback paths.
