ACE701C
High Efficiency Low Noise PFM Boost DC/DC Converter
Description
The ACE701C 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 ACE701C 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, ACE701C is well considerated in circuit design and
manufacture. So that the interferer to other circuits by the device is reduced greatly.
ACE701C integrates stable reference circuits and trimming technology, so it can afford high precision
and low temperature-drift coefficient of the output voltage.
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 2.5V½6.0V(In 0.1V step)
Output voltage accuracy
2%
