MPQ4570規(guī)格書詳情

MPQ4570屬于集成電路(IC)的穩(wěn)壓器-DC-DC開關穩(wěn)壓器。由美國芯源系統(tǒng)有限公司制造生產(chǎn)的MPQ4570穩(wěn)壓器 - DC-DC 開關穩(wěn)壓器DC-DC 開關穩(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元件,設備提供的電力會通過該元件。

DESCRIPTION

The MPQ4570 is a frequency programmable

step-down switching converter with integrated

internal high-side and low side power MOSFETs.

It can provide 3A continuous output current with

peak current control for excellent transient

response and efficiency performance.

The wide 4.5V to 55V input voltage range

accommodates a variety of step down

applications, including those applications in

industrial, PoE, automotive and printer with DC

high voltage bus.

The MPQ4570 uses peak current mode control to

regulate the output voltage. The chip provides

over current protection with valley current

detection which is used to avoid current running

way. Also it has accurate and reliable over

voltage protection, and auto recovery thermal

protection. In addition, the optional external soft

start is available. Enable and power good

indication function can be used to power track

easily. In order to increase the efficiency,

MPQ4570 will automatically scaling down the

switching frequency when load is light.

Meanwhile, the low side MOSFET will be turned

off to reduce driver loss when zero inductor

current is detected. MPQ4570 also features as

a fully integrated solution with both high side

and low side power MOSFETs. Synchronous

operation mode with integrated low side

MOSFET is much helpful to reduce the

conduction loss and also beneficial to reduce

external components space and save the cost.

The MPQ4570 is available in a TSSOP-20 EP

with exposed pad package.
