LED array drivers
STP04CM05
The STP04CM05 is a high-power LED driver and 4-bit shift register designed for
power LED applications. The STP04CM05 contains a 4-bit serial in, parallel out
shift register that feeds a 4-bit D-type storage register. In the output stage, four
regulated current sources are designed to provide 80 to 400 mA constant current
to drive the high powered LEDs.
The STP04CM05 family guarantees 20 V output driving capability, allowing users
to connect more LEDs in series. The high clock frequency, 30 MHz, also satisfies
the system requirements which include high-volume data transmission. The
STP04CM05 is well suited for very high brightness displays and special lighting
applications. The STP04CM05 is offered in DIP-14, SO-14 and TSSOP16 exposed
pad packages.
