ACE705 controller equivalent, step-up dc/dc controller.
make ACE705 series be suitable for the portable devices, which are supplied by a single battery to four-cell batteries. ACE705 has a drive pin (EXT) for external transist.
If DC-DC converter delivers large output current (for example: output current is great than 50mA), large inductor value.
The ACE705 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 6uA. It is capable of delivering 500mA output current at 4.0V output with 2.
