BL8531

BL8530系列是PFM控制的开关型DC/DC升压稳压芯片。

BL8531series are CMOS-based PFM step-up DC-DC Converter. The converter can start up bysupply voltage as low as 0.8V, and apable ofdelivering maximum 200mA output current at3.3V 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 anufacture. So that the interferer to other circuits by the device is reduced greatly.

BL8531integrates stable reference circuits and trimming technology, so it can afford high precision and low temperature-drift coefficient of
the output voltage.

BL8531 is available in SOT-89-3, SOT-23-3,SOT-23-5andTO-92 packages, which is PB free. And in5-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.
