1 / 10 page ACE701C High Efficiency Low Noise PFM Boost DC/DC Converter VER 1.3 1 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 2.5V~6.0V(In 0.1V step) Output voltage accuracy 2% Low temperature-drift coefficient of the output voltage 100ppm/℃ Only three external components are necessary: An inductor, a Schottky diode and an output filter capacitor High power conversion efficiency 85% Low quiescent current drawn from power source <5.5uA Application Power source for PDA. DSC. MP3 Player. electronic toy and wireless mouse Power source for a single or dual-cell battery-powered equipments Power source for LED Absolute Maximum Ratings Parameter Symbol Max Unit Input supply voltage VIN -0.3~12 V Input voltage VI(LX) -0.3~Vout+0.3 V CE pin voltage -0.3~Vout+0.3 Lx pin output current 0.7 A Power Dissipation SOT-23-3 250 mW Operating Junction temperature TJ 125 OC Storage temperature TS - 40 to 150 OC Ambient temperature Ta -40 to 85 OC |
