BL8531 - High Efficiency Low Noise PFM Step-up DC/DC Converter

General Description

BL8531 High Efficiency Low Noise PFM Step-up DC/DC Converter

Key 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.

DESCRIPTION BL8531 High Efficiency Low Noise PFM Step-up DC/DC Converter 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.
