STP16CPS05中文资料具有自动节能功能的低压16位恒定电流LED灌驱动器数据手册ST规格书

描述 Description

The STP16CPS05 is a monolithic, low voltage, low current power 16-bit shift register designed for LED panel displays. The STP16CPS05 contains a 16-bit serial-in, parallel-out shift register that feeds a 16-bit, D-type storage register. In the output stage, sixteen regulated current sources provide from 5 mA to 100 mA constant current to drive the LEDs. The auto power shut-down and auto power-ON feature allows the device to save power without any external intervention. The output current setup time is 40 ns (typ.), thus improving the system performance. The LEDs' brightness can be controlled by using an external resistor to adjust the STP16CPS05 output current. The STP16CPS05 guarantees a 20 V output driving capability, allowing users to connect more LEDs in series. The high clock frequency, 30 MHz, makes the device suitable for high data rate transmission. The 3.3 V voltage supply is useful in applications that interface with a 3.3 V microcontroller.

简介

STP16CPS05属于集成电路（IC）的LED驱动器。由制造生产的STP16CPS05LED 驱动器器件属于 LED 驱动器电源管理集成电路 (PMIC) 系列，可通过标称固定电压的电源为负载（通常为发光二极管）提供电流，并且电流可控。它与用于电压调节的类似产品的主要区别在于，这类器件提供较低的反馈电压（以提高系统能效），而且通常可对器件工作点进行外部控制，可在照明应用中用于实现调光功能。
