BL8531C High Efficiency, Multi-Function Step-up DC/DC Controller DESCRIPTION FEATURES  BL8531C series are CMOS-based PFM step-up DCDC Controller with low supply current and high output voltage accuracy. Quiescent current drawn from power source is as low as 6uA. It is capable of delivering 500mA output current at 4.0V output with 2V input Voltage. Only four external components are necessary: An inductor, a Schottky diode, an output filter capacitor and a NMOSFET or a NPN transistor All of these features make BL8531C series be suitable for the portable devices, which are supplied by a single battery to four-cell batteries. BL8531C has a drive pin (EXT) for external transistor. So it is possible to load a large output current with a power transistor which has a low voltage dropout. BL8531C integrates stable reference circuits and trimming technology, so it can afford high precision and low temperature-drift coefficient of the output voltage. BL8531C is available in SOT-23-3, SOT-23-5 and SOT-89-3 packages which are PB free. And in SOT23-5 the device can be switch on or off easily by CE pin, to minimize the standby supply current.        Deliver 500mA at 4.0V Output voltage with 2V input Voltage The controller 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/C Only four external components are necessary: An inductor, a Schottky diode, an output filter capacitor and a NMOSFET or a NPN transistor High power conversion efficiency----------90％ Low quiescent current drawn from power source--------------------------------------------- 6uA Small package--SOT-23-3, SOT-23-5, SOT-89-3 APPLICATIONS    TYPICAL APPLICATION Power source for PDA, DSC, MP3 Player, electronic toy and wireless mouse Power source for a single or dual-cell batterypowered equipments Power source for LED ELECTRICAL CHARACTERISTICS BL8531C www.belling.com.cn 1  PDF
