名片曝光使用說明

步驟1:創(chuàng)建名片

微信掃描名片二維碼,進(jìn)入虎易名片小程序,使用微信授權(quán)登錄并創(chuàng)建您的名片。

步驟2:投放名片

創(chuàng)建名片成功后,將投放名片至該產(chǎn)品“同類優(yōu)質(zhì)商家”欄目下,即開啟名片曝光服務(wù),服務(wù)費(fèi)用為:1虎幣/天。(虎幣充值比率:1虎幣=1.00人民幣)

關(guān)于曝光服務(wù)

名片曝光只限于使用免費(fèi)模板的企業(yè)產(chǎn)品詳細(xì)頁下,因此當(dāng)企業(yè)使用收費(fèi)模板時(shí),曝光服務(wù)將自動(dòng)失效,并停止扣除服務(wù)費(fèi)。

無錫禾芯微低功耗降壓DC-DC HX4004A:

The HX4004A is a low noise switched capacitor

voltage doubler. It produces a regulated output

voltage from a 2.7V to 4.5V input. Low external

parts count (one flying capacitor and two small

bypass capacitors at VIN and VOUT) make the

HX4004A ideally suited for small,

battery-powered applications.

The HX4004A have thermal shutdown

capability and can survive a continuous short

circuit from VOUT to GND. A low current

shutdown feature disconnects the load from VIN

and reduces quiescent current to <1μA.

The HX4004A is available in the industry

standard SOT-23-6L power packages.

Fixed 4.94V±3% Output

? VIN Range: 2.7V to 4.5V

? Output Current: Up to 110mA (VIN≥3V)

Up to 230mA (VIN≥3.6V)

? Low Noise Constant Frequency (360kHz)

Operation

? Shutdown Current <1μA

? No Inductors

? Available in Low Profile 6-Lead SOT23
