Overvoltage Protection Circuit In a constant-vo
Features
- Adoption of Sanyo IMST ; Insulated Metal Substrate Technology, allows the circuit to be operated without using a heat sink (see “No Fin Output Current Derating” chart in the page 6).
- Typical efficiency of 90% at DC 12V input, 2.5A output.
- Fine adjustment of output voltage enable.
- 50 kHz operating frequency.
- Low-RON resistance power MOSFET adopted.
- Low-VF Schottky barrier diode adopted. Any and all SANYO products described or contained.
