特点 High Voltage: Operation Up to 60V High Current: N-Channel Drive Handles Up to 10,000pF Gate Capacitance Programmable Average Current Limiting5V Reference Output with 10mA External Loading CapabilityFixed Frequency Current Mode OperationOscillator Synchronizable Up to 200kHzUndervoltage Lockout with HysteresisProgrammable Start Inhibit for Power Supply Sequencing and ProtectionUser Adjustable Slope Compensation典型应用典型应用描述The LT1680 incorporates programmable average current limiting allowing accurate limiting of DC current in the magnetics, independent of ripple current. User adjustable slope compensation provides stable operation at duty cycles up to 90%.The LT1680 operating frequency is programmable and can be synchronized up to 200kHz. Minimum off-time operation provides switch protection. The IC also incorporates a soft start feature that is gated by both shutdown and undervoltage lockout conditions.
