LT8641規(guī)格書詳情
LT8641屬于集成電路(IC)的穩(wěn)壓器-DC-DC開關(guān)穩(wěn)壓器。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的LT8641穩(wěn)壓器 - DC-DC 開關(guān)穩(wěn)壓器DC-DC 開關(guān)穩(wěn)壓器 PMIC(電源管理集成電路)產(chǎn)品族中的產(chǎn)品是元器件級設(shè)備,用于需要穩(wěn)定 DC 輸入電壓和/或?qū)⑵滢D(zhuǎn)換為不同幅度的輸出電壓的應(yīng)用。這些器件與稱為“控制器”PMIC 的類似產(chǎn)品的區(qū)別在于集成了主開關(guān)元件,設(shè)備提供的電力會通過該元件。
GENERAL DESCRIPTION
The LT?8638-2 synchronous step-down regulator
features the Silent Switcher? architecture designed to
minimize EMI emissions while delivering high efficiency
at high switching frequencies. This performance makes
the LT8638-2 ideal for noise sensitive applications and
environments.
The fast, clean, low overshoot switching edges enable
high efficiency operation even at high switching
frequencies, leading to a small overall solution size.
Peak current mode control with a 25ns minimum ontime
allows high step down ratios even at high switching
frequencies. External compensation through the VC pin
allows for fast transient response. PolyPhase operation
allows multiple LT8638-2 regulators to run with
interleaving phase shift to provide more output current.
Burst Mode operation enables low standby current
consumption, forced continuous mode can control
frequency harmonics across the entire output load
range, or spread spectrum operation can further reduce
EMI emissions. Soft-start and tracking functionality is
accessed through the SS pin, and an accurate input
voltage UVLO threshold can be set using the EN/UV pin.
