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
