BL8530C Datasheet | BELLING

HIGH EFFICIENCY, LOW SUPPLY CURRENT, MULTI-FUNTION STEP-UP DC/DC CONTROLLER OUTLINE The BL8530C series are CMOS-based PFM step-up DC-DC Controller with low supply current and high output voltage accuracy. Quiescent current drawn from power source is as low as 6u A. It is capable of delivering 500m A output current at 4.0V output with 2V input Voltage. Only four external ponents are necessary: An inductor, a Schottky diode, an output filter capacitor and a NMOSFET or a NPN transistor All of these Features make BL8530C series be suitable for the portable devices, which are supplied by a single battery to four-cell batteries. BL8530C 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 saturation voltage. BL8530C integrates stable reference circuits and trimming technology, so it can afford high precision and low temperature-drift coefficient of the output voltage. BL8530C is available in SOT-23-3 and SOT-23-5 packages which are PB free. And in SOT-23-5 the device can be switch on or off easily by CE pin, to minimize the standby supply current.
