LT3942規(guī)格書詳情
LT3942屬于集成電路(IC)的LED驅(qū)動(dòng)器。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的LT3942LED 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 LT?8350 is a monolithic 4-switch synchronous buckboost
converter with Silent Switcher architecture to minimize
EMI emissions while delivering high efficiency at
high switching frequency. The switcher can regulate the
output voltage, input or output current from input voltages
above, below, or equal to the output voltage. The
proprietary peak current mode control scheme allows
adjustable and synchronizable 200kHz to 2MHz fixed frequency
operation, or spread spectrum frequency modulation
(SSFM) operation. With 3V to 40V input voltage
range, 1V to 18V output voltage capability, and seamless
low noise transitions between operation regions, the
LT8350 is ideal for voltage regulator, battery and supercapacitor
charger applications in automotive, industrial,
telecom, and battery powered systems.
The LT8350 provides input or output current monitor and
power good flag. Robust fault protection is provided to
detect output short-circuit condition, during which the
LT8350 retries, latches off, or keeps running.
