Description
The SI-8001FFE DC voltage regulator is a DC-to-DC buck convertor that attains an oscillation frequency of 300 kHz, and has an integrated miniaturized choke coil, allowing it to serve as a small, high efficiency power supply in a compact TO220F package.
Features and Benefits
⢠3.5 A output current supplied in a small, through-hole mount power package
⢠High efficiency: 83% at VIN= 15 V, IO= 2.0 A,VO= 5 V
⢠Requires only six external components (optional soft start requires an additional capacitor)
⢠Oscillation circuit built-in (frequency 300 kHz typical)
⢠Constant-current mode overcurrent protection circuit and overtemperature protection circuit built-in
⢠Soft start function built-in (can be implemented as an on/off function; output-off state at low level)
⢠Low current consumption during output-off state
Applications include:
⪠DVD recorder
⪠FPD TV
⪠Telecommunications equipment
⪠Office automation equipment, such as printers
⪠On-board local power supply
⪠Output voltage regulator for second stage of SMPS (switched mode power supply)
