• Can decrease a rush current
• Boost : Pulse by pulse over current protection function
• Over current protection
• Boost mode: Short circuit protection function (constant timer: 1.6ms)
• Short circuit protection
• LDO mode: Over current limiter (fold-back characteristics)
• Can limit a over current
• Common: Under voltage lockout
• Prevention of instability operation in under voltage
• Common: Thermal shut down
• Thermal protection
• Common: Power good function plus Power good delay time setting
• Stability operation
• Common: Output voltage selectable function from two kinds of voltage
• Can select the output voltage

应用 Application

• Boost convertor attached LDO function
• Power supply for BS/CS parabola antenna
