BL8530 PFM STEP-UP DC/DC CONVERTER WITH HIGH EFFICIENCY AND LOW NOISE OUTLINE
：
FEATURES
： • Deliver 200mA at 3.3V Output voltage The BL8530 series are CMOS-based PFM with 1.8V input Voltage step-up DC-DC Converter. The converter can start up by supply voltage as low as 0.8V, and • Low start-up voltage (when the output capable of delivering maximum 200mA output current is 1mA)--------------------------0.8V current at 3.3V output with 1.8V input Voltage. • The converter output voltage can be Quiescent current drawn from power source is adjusted from 2.5V～6.0V(In 0.1V step). as low as 7uA. All of these features make BL8530 series be suitable for the portable • Output voltage accuracy -----------±2％ devices, which are supplied by a single battery • Low temperature-drift coefficient of the to four-cell batteries. To reduce the noise caused by the switch output voltage------------------±100ppm/℃ regulator, BL8530 is well considerated in circuit • Only three external components are design and manufacture. So that the interferer necessary: An inductor, a Schottky diode to other circuits by the device is reduced and an output filter capacitor greatly. • BL8530 integrates stable reference High power conversion efficiency---85％ circuit s and trimming technology, so it can • Low quiescent current drawn from power af ford high precision and low temperature-drift source------------------------------------- <7uA coef ficient of the output voltage. BL8530 is available in SOT-89-3 、
APPLICATIONS
： SOT- 23-3 and SOT-23-5 packages which is PB • Power source for PDA、DSC、MP3 free. And in 5-pin packages, such as Player、electronic toy and wireless mouse SOT-23-5, the device can be switch on or off easily by CE pin, to minimize the standby • Power source for a single or dual-cell supply current. battery-powered equipments • Power source for LED
