JAJSEQ6B February 2010 – February 2018 LM48580
PRODUCTION DATA.
The LM48580 boost converter requires three external capacitors for proper operation: a 1 μF supply bypass capacitor, and 1 μF + 100 pF output reservoir capacitors. Place the supply bypass capacitor as close to VDD as possible. Place the reservoir capacitors as close to VBST and VAMP as possible. Low ESR surface-mount multi-layer ceramic capacitors with X7R or X5R temperature characteristics are recommended. Select output capacitors with voltage rating of 25 V or higher. Tantalum, OS-CON and aluminum electrolytic capacitors are not recommended. See Table 2 for suggested capacitor manufacturers.
