DESCRIPTION
A7530 is CMOS-based PFM step-up DC-DC converter. High Power Conversion Efficiency: 85% Low Quiescent Current Drawn from Power Source: <7uA o 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 7uA. All of these features make A7530 be suitable for the portable devices, which are supplied by a single battery for four-cell batteries. To reduce the noise caused by the switch regulator, A7530 is well considerate in circuit design and manufacture. So that the interferer to other circuits by the device is reduced greatly. The A7530 integrates stable reference circuits and trimming technology, so it can afford high precision and low temperature-drift coefficient of the output voltage. The A7530 is available in SOT-23 and SOT-25 package. And in SOT-25 package, the Application Portable Source for PDA, DSC, MP3 Player, Electronic Toyu and Wireless Mouse Powe...
