EVKT-8861屬于開發(fā)板套件編程器的評估板-DC/DC與AC/DC（離線）SMPS。由美國芯源系統(tǒng)有限公司制造生產(chǎn)的EVKT-8861評估板 - DC/DC 與 AC/DC（離線）SMPS該系列產(chǎn)品提供了一種方便的方法，可對開關(guān)模式電源轉(zhuǎn)換所用的器件（包括 DC-DC 和 AC-DC 型）進(jìn)行性能或特性評估?！胺€(wěn)壓器”（包含內(nèi)部電源開關(guān)裝置）和“控制器”（設(shè)計為控制外部電源開關(guān)）之類的器件均包括在內(nèi)。

DESCRIPTION

The MP8861 is a high-frequency, synchronous,

rectified, step-down, switch-mode converter

with an I2C control interface. The MP8861 offers

a fully integrated solution that achieves 6A of

continuous output current with excellent load

and line regulation over a wide input supply

range.

The output voltage level can be controlled onthe-

fly through an I2C serial interface. The

reference voltage range can be adjusted from

0.6V to 1.108V in 4mV steps. The voltage slew

rate, frequency, current limit, hiccup/latch-off

protection, enable, and power-save mode (PSM)

are also selectable through the I2C interface.

Constant-on-time (COT) control operation

provides fast transient response. An open-drain

power good (PG) pin indicates that the output

voltage is in the nominal range. Full protection

features include over-voltage protection (OVP),

over-current protection (OCP), and thermal

shutdown.

The MP8861 is available in a QFN-14

3mmx4mm) package.
