PFM STEP-UP DC/DC CONVERTER WITH HIGH EFFICIENCY AND LOW NOISE OUTLINE£º Features £º The BL8530 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 200m A output current at 3.3V output with 1.8V input Voltage. Quiescent current drawn from power source is as low as 7u A. All of these Features make BL8530 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, BL8530 is well considerated in circuit design and manufacture. So that the interferer to other circuits by the device is reduced greatly. BL8530 integrates stable reference circuits and trimming technology, so it can afford high precision and low temperature-drift coefficient of the output voltage. BL8530 is available in SOT-89-3 ¡¢ SOT-23-3 and SOT-23-5 packages which is PB free. And in 5-pin packages, such as SOT-23-5, the device can be switch on or off easily by CE pin, to minimize the standby supply current. - - - - - - - - - - - Deliver 200m A at 3.3V Output voltage with 1.8V input Voltage Low start-up voltage (when the output current is 1m A)--------------------------0.8V The converter output voltage can be adjusted from 2.5V¡« 6.0V(In 0.1V step).
