Overview
Ordering number:ENN1709C Thick Film Hybrid IC STK795 Chopper Type Voltage Regulator Features • Self-oscillation type chopper regulator power IC using Sanyo’s original IMST (Insulated Metal Substrate Technology) substrate.
• The STK795, being a 5V chopper IC, is more advantawww.
DataSheet4U.
com geous in the following points as compared with series regulator (dropper type) ICs.
1.
Possible to provide a 5V output power supply circuit with high efficiency.
2.
Since the input voltage range is wide, no more than one rectifying/smoothing circuit is required to provide a multi-output power supply circuit which also delivers 12V or 24V output.
• Functional trimming is used to set 5V output with high accuracy.
• Cutoff function to cut off output voltage by external signal.
• Contains a transistor for overcurrent protector (foldback characteristic) and possibel to set the protection level externally.
