STP04CM05中文资料4位恒定电流电源-LED灌驱动器数据手册ST规格书

描述 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 D-type 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.

The STP04CM05 is well suited for very high brightness displays and special lighting applications.

The STP04CM05 is offered in TSSOP16 exposed pad package.

简介

STP04CM05属于集成电路（IC）的LED驱动器。由ST制造生产的STP04CM05LED 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。
