Description

The ACE701 series are CMOS-based PFM step-up DC-DC Converter. The converter can start up by

supply voltage as low as 0.8V, and capable of delivering maximum 200mA output current at 3.3V output

with 1.8V input Voltage. Quiescent current drawn from power source is as low as 5.5uA. All of these

features make ACE701 series be suitable for the portable devices, which are supplied by a single battery

to four-cell batteries.

To reduce the noise caused by the switch regulator, ACE701 is well considerated in circuit design and

manufacture. So that the interferer to other circuits by the device is reduced greatly.

ACE701 integrates stable reference circuits and trimming technology, so it can afford high precision and

low temperature-drift coefficient of the output voltage.

ACE701 is available in SOT-89-3、SOT-23-3、SOT-89-5 and SOT-23-5 packages which is PB free. And

in 5-pin packages, such as SOT-23-5 and SOT-89-5, the device can be switch on or off easily by CE pin,
