BL8531C - Multi-Function Step-up DC/DC Controller
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 nec
BL8531C 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
