• Manufacturer Part Number: S-8327
• Description: (S-8323 / S-8327) SMALL PACKAGE PWM CONTROL STEP-UP SWITCHING REGULATOR
• Manufacturer: Seiko

Precautions








Mount external capacitors, a diode, and a coil as near as possible to the IC.
Ripple voltage and spike noise occur in switching regulators. Because they largely depend on the coil and the capacitor
used, check them using an actually mounted model.
Seiko Instruments shall not be responsible for any patent infringement by products including S-8323/8327 Series in
connection with the method of using S-8323/8327 Series in such products, the specification of such products, or the country
of destination thereof.
Make sure dissipation of the switching transistor (especially at a high temperatures) does not exceed the allowable power
dissipation of the package.
