MP4658GS-Z規(guī)格書詳情

MP4658GS-Z屬于集成電路(IC)的LED驅(qū)動(dòng)器。由美國芯源系統(tǒng)有限公司制造生產(chǎn)的MP4658GS-ZLED 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,可通過標(biāo)稱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?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 MP4658 is a 4-string, secondary-side LED

driver for LED backlighting, and is ideal for

monitor and small-sized TV LED backlighting. It

controls the flyback power stage to regulate the

LED current loop and the output supply voltage.

The MP4658 integrates 4-string LED current

balancing. Powered by a 6V to 36V input supply

voltage (VIN), the MP4658 outputs a

compensation signal to control the primary-side

flyback (or other power stage) via an

optocoupler to regulate the output voltage

(VOUT).

The MP4658 supports analog dimming and

PWM dimming to the LED current through the

ADIM and PDIM pins. For analog dimming,

apply a pulse signal with a frequency above

5kHz to the ADIM pin. For PWM dimming, apply

a low-frequency PWM signal to the PDIM pin.

The MP4658 also supports analog mode PWM

dimming to the LED current, which makes the

LED current rise and fall softly.

The MP4658 features numerous smart

protections to increase system reliability,

including open LED protection, short LED string

protection, LEDx short-to-ground protection, FB

over-voltage protection (OVP), feedback open

protection, and thermal protection. The MP4658

is available in an SOIC-16 package.
