STP16CPC26数据手册集成电路（IC）的LED驱动器规格书PDF

描述 Description

The STP16CPC26 is a monolithic, low voltage, 16-bit constant current LED sink driver. The device contains a 16-bit shift register and data latches, which convert serial input data into parallel output format. In the output stage sixteen regulated current generators provide 5 mA to 90 mA constant current to drive LEDs. The current is externally adjusted through a resistor. LED brightness can be adjusted from 0% to 100% via OE pin.

The STP16CPC26 guarantees a 20 V driving capability, allowing users to connect more LEDs in series to each current source.

The high 30 MHz clock frequency makes the device suitable for high data rate transmission.

The thermal shutdown (170 °C with about 15 °C hysteresis) assures protection from overtemperature events.

The STP16CPC26 is housed in four different packages: QSOP24, SO-24, TSSOP-24 and HTSSOP-24 (with exposed pad).

简介

STP16CPC26属于集成电路（IC）的LED驱动器。由制造生产的STP16CPC26LED 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。
