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

BL8531 High Efficiency Low Noise PFM Step-up DC/DC Converter DESCRIPTION FEATURES BL8531 series are CMOS-based PFM step-up DCDC 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 BL8531 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, BL8531 is well considerate in circuit design and manufacture, so that the interferer to other circuits by the device is reduced greatly. • • BL8531 integrates stable reference circuits and trimming technology, so it can afford high precision and low temperature-drift coefficient of the output voltage. Deliver 200mA at 3.3V Output voltage with 1.8V input Voltage Low start-up voltage (when the output current is 1mA)-----------------------------0.8V 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 APPLICATIONS • BL8531 is available in SOT-89-3, SOT-23-3, SOT23-5 and TO-92 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. • • TYPICAL 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 ELECTRICAL CHARACTERISTICS Output Voltage VS.
