Product details

Description

Pin Symbol Type Description 1 Vout OUTPUT, PWR This pin supplies the regulated voltage to the external LED.Since high current transients are present in this pin, care must be observed to avoid voltage spikes in the system.Good high frequency layout technique must be observed.2 C1N POWER One side of the external charge pump capacitor (CFLY) is connected to this pin, associated with C1P, pin 9. Using low ESR ceramic capacitor is recommended to optimize the Charge Pump efficiency.3 Vbat
