STK795

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.
