SSL2103

Dimmable Greenchip controller for LED lighting

11. Characteristics

Table 6. Characteristics

T amb = 25 ? C; no overtemperature; all voltages are measured with respect to ground; currents are positive when flowing into

the IC; V CC = 20 V and PWMLIMIT and BRIGHTNESS pins are disconnected unless otherwise specified. Typical frequency

100 kHz.
