BL8534 - Belling

BL8534 High Efficiency Low Noise PFM Step-up DC/DC Converter

BL8534 series are CMOS-based PFM stepup DC-DC 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 20uA. All of these features make BL8534 series be suitable for the portable devices, which a.

Features

make BL8534 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, BL8534 is well considerated in circuit design and manufacture. So that the interferer to other circuits by the device is reduced greatly. BL8534 integrates stable reference circuits and trimming technology, so it can afford high precision and low temperature-drift coefficient of the output voltage. BL8534 is available in SOT-89-3, SOT-23-3, SOT-23-5 and TO-92 packages that are PB free. And in 5-pin packages, such as SOT-235,.
