General Description
The CRD1615A-8W reference design demonstrates the
performance of the CS1615A single stage dimmable
AC/DC LED driver IC with a 250mA output driving
10

LEDs in series. The CS1615A is designed to support
a reduced off-chip BOM compared to the CS1615. It
offers best-in-class dimmer compatibility and minimum
dimming performance with leading-edge, trailing-edge, and
digital dimmers. The form factor is targeted to fit into many
LED bulb applications (GU10, A19-type, PAR, BR).
