A8516ELPTR-T規(guī)格書詳情

A8516ELPTR-T屬于集成電路(IC)的LED驅(qū)動器。由Allegro MicroSystems制造生產(chǎn)的A8516ELPTR-TLED 驅(qū)動器器件屬于 LED 驅(qū)動器電源管理集成電路 (PMIC) 系列,可通過標稱固定電壓的電源為負載(通常為發(fā)光二極管)提供電流,并且電流可控。它與用于電壓調(diào)節(jié)的類似產(chǎn)品的主要區(qū)別在于,這類器件提供較低的反饋電壓(以提高系統(tǒng)能效),而且通??蓪ζ骷ぷ鼽c進行外部控制,可在照明應用中用于實現(xiàn)調(diào)光功能。

Description

The A8516 is a multi-output WLED/RGB driver for backlighting LCD monitors and televisions. It integrates a boost controller to drive external MOSFET, and six internal currentsinks. The boost converter operates in constant frequency (programmable) current mode control.

The LED sink current is set by an external R_ISET resistor (see chart below). More than one LED sinks can be combined together to achieve even higher current per LED string.

The A8516 operates from a single supply of 8 to24 V. It provides protection against overvoltage, open or shorted LED string, and overtemperature. A dual level cycle-by-cycle current limit function provides soft start and protects against overloads.

Features and Benefits

? Six integrated high current sinks

? Fixed frequency current mode control with integrated gate driver

? 300 kHz to 1 MHz adjustable Boost switching frequency

? Controlled startup using options of Enable, PWM signal, or battery voltage ramp

? Active current sharing between LED strings for ±0.6 accuracy and matching

? No audible MLCC noise during PWM dimming

? Adjustable overvoltage protection (OVP)

? Open or shorted LED string protection

? Overtemperature, cycle-by-cycle current limit, and undervoltage protection

? SOIC 24-pin package for easy single-side PCB manufacturing, or TSSOP 24-pin package with exposed thermal pad for better thermal performance
