TLD5095EL数据手册集成电路（IC）的LED驱动器规格书PDF

描述 Description

The TLD5095EL is a LED boost controller with built in protection features. The controller concept of the TLD5095EL allows multiple configurations such as Boost, Buck, Buck-Boost, SEPIC and Flyback by simply adjusting the external components. TLD5095EL is the simplest member of the TLD509x series and comes with reduced maximum output voltage of 45V, less current accuracy and is missing the analog dimming feature as well as a short to ground protection.

特性 Features

• Single-Channel Multitopology (B2B, B2G, SEPIC, Flyback) DC/DC Controller
• Constant Current or Constant Voltage Regulation
• Wide Input Voltage Range from 4.75 V to 45 V
• Very Low Shutdown Current: IQ< 10 μA
• Switching Frequency Range from 100 kHz to 500 kHz
• Synchronization with external clock source
• Output Open Circuit Diagnostic Output
• PWM Dimming
• Internal Soft Start
• 300mV High Side Current Sense to ensure highest flexibility and LED current accuracy
• Internal 5 V Low Drop Out Voltage Regulator
• Wide LED current range via simple adaptation of external components
• Output Overvoltage Protection
• Over Temperature Shutdown
• Available in a small thermally enhanced PG-SSOP-14 package
• Automotive AEC Qualified


优势:

应用 Application

• Automotive interior and exterior lights
• LED daytime running lights, Low Beam, High Beam or combined Low- and Highbeams
• Pre-regulator e.g. for rear light applications

简介

TLD5095EL属于集成电路（IC）的LED驱动器。由制造生产的TLD5095ELLED 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。
