ACE701D

PFM STEP-UP DC/DC Converter with High Efficiency and Low Noise

Description

The ACE701D 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 ACE701D 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, ACE701D is well considerate in circuit design and

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

ACE701D integrates stable reference circuits and trimming technology, so it can afford high precision

and low temperature-drift coefficient of the output voltage.
