STP16CPPS05 is a low voltage 16-bit constant current LED sink driver with auto power-saving feature. It has adjustable output current, serial data input/parallel data output, 3.3V MCU-driving capability, etc.
The STP16CPPS05 is a monolithic, low-voltage, low-current power 16-bit shift register designed for LED panel displays. It features a 16-bit serial-in, parallel-out shift register that feeds a 16-bit D-type storage register, driving sixteen regulated current sources to provide 3 to 40 mA of constant current to LEDs.
The device supports a low voltage power supply down to 3 V and includes an auto power-saving feature to reduce consumption. It offers a 30 MHz clock frequency and is available in high thermal efficiency TSSOP packages with an exposed pad. The output current is adjustable through an external resistor, and brightness can be controlled via the OE pin.
