Description
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 Dtype storage register. In the output stage, four regulated current sources were designed to provide 80-400 mA constant current to drive high power LEDs.
The STP04CM05 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. […]
