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).
• Slim package reduces mounting space.
• Typical efficiency of 88% at DC 5V 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 herein do not have specifications that can handle applications that require extremely high levels of reliabili.
