SC620数据手册集成电路（IC）的LED驱动器规格书PDF

描述 Description

The SC620 is a multi-purpose LED driver with eight identical, independently controlled current sinks. Each current sink can drive an LED by connecting the LED’s anode to the system power supply and the cathode to the current sink input pin. Any combination of outputs can be enabled or disabled for optimal design flexibility.

特性 Features

·Eight identical current drivers with independent control
·Wide current setting range - 31.25μA to 25mA
·5% current matching, 7% accuracy
·I2C interface for microprocessor control
·I2C slave address 1110 000x
·Less than 1μA quiescent current in shutdown
·Low dropout voltage: ≤ 150mV
·Over-temperature protection
·MLPQ-UT-16 package (3mm x 3mm)
·Ultra-thin 0.6mm maximum package height
·Fully WEEE and RoHS compliant

应用 Application

·LCD backlighting LED driver
·Multicolor and RGB LED driver
·General purpose current sink array
·General purpose digital output (open-drain) expander
·Auto-focus voice-coil driver

简介

SC620属于集成电路（IC）的LED驱动器。由制造生产的SC620LED 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。
