A8515規(guī)格書(shū)詳情

A8515屬于集成電路(IC)的LED驅(qū)動(dòng)器。由Allegro MicroSystems制造生產(chǎn)的A8515LED 驅(qū)動(dòng)器器件屬于 LED 驅(qū)動(dòng)器電源管理集成電路 (PMIC) 系列,可通過(guò)標(biāo)稱(chēng)固定電壓的電源為負(fù)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(lèi)似產(chǎn)品的主要區(qū)別在于,這類(lèi)器件提供較低的反饋電壓(以提高系統(tǒng)能效),而且通常可對(duì)器件工作點(diǎn)進(jìn)行外部控制,可在照明應(yīng)用中用于實(shí)現(xiàn)調(diào)光功能。

Description

The A8515 is a multi-output white LED (WLED) driver for LCD backlighting in consumer and industrial displays. It integrates a current-mode boost converter with an internal power DMOS switch and two current sinks. The boost converter can drive up to 24 LEDs: 12 LEDs per string at 120 mA. The LED sinks can be paralleled together to achieve higher LED currents, up to 240 mA. The A8515 can operate from a single power supply, from 5 to 40 V.

Features and Benefits

? Wide input voltage range: 5 to 40 V

? Maximum LED current of 120 mA

? TSSOP-16 (LP) package; exposed pad offers best-in-class thermal performance

? Typical LED accuracy of 0.5, and 0.5 for LED-to-LED matching

? Internal bias supply for single-supply operation (typically between VIN = 8 to 24 V)

? Integrated boost converter with 60 V DMOS switch with overvoltage protection (OVP)

? Drives up to 12 series LEDs in 2 parallel strings

? Single EN/PWM pin interface for both PWM dimming and enable function

? Sync function to synchronize boost converter switching frequencies up to 2.3 MHz, this gives the designer the ability minimize component size

? Provides driver for external PMOS input disconnect switch

? Protection features:

? Open or shorted VLED pin protection

? Open Schottky protection

? Cycle-by-cycle current limit

? Overtemperature protection (OTP)

? Output short circuit protection

Applications

? Desktop LCD flat panel displays (FPD)

? Flat panel video displays

? LCD TVs and monitors
