  www.DataSheet4U.com                                                                                          ACE701                                               Technology PFM STEP-UP DC/DC Converter with High Efficiency and Low Noise 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, to minimize the standby supply current.  Features Deliver 200mA at 3.3V Output voltage with 1.8V input Voltage Low start-up voltage (when the output current is 1mA)--------------------------0.8V The converter output voltage can be adjusted from 2.5V～...
