特点Wide Input Range: 5.5V to 60V3A Peak Switch Current over All Duty Cycles Constant 200kHz Switching Frequency 200kHz(LT3430) 100kHz(LT3430-1) 0.1 Ω Switch Resistance Current ModeEffective Supply Current: 2.5mAShutdown Current: 30μA1.2V Feedback Reference VoltageEasily SynchronizableCycle-by-Cycle Current LimitingSmall, 16-Pin Thermally Enhanced TSSOP Package典型应用典型应用描述Special design techniques and a new high voltage process achieve high efficiency over a wide input range. Efficiency is maintained over a wide output current range by using the output to bias the circuity and by utilizing a supply boost capacitor to saturate the power switch. Patented circuity* maintains peak switch current over the full duty cycle range. A shutdown pin reduces supply current to 30μA and a SYNC pin can be externally synchronized with a logic level input from 228kHz to 700kHz for the LT3430 or from 125kHz to 250kHz for the LT3430-1.The LT3430/LT3430-1 are available in a thermally enhanced 16-pin TSSOP package.
