A7530
Description
A7530 is CMOS-based PFM step-up DC-DC converter. The converter can start up by
Features
Deliver 200m A at 3.3V Output Voltage with 1.8V Input Voltage Low Start-Up Voltage @1m A:0.8V The Converter Output Voltage Can Be Adjusted From 2.5V~6.0V (in 0.1V step) Output Voltage Accuracy:±2% Low Temperature-Drift Coefficient of the Output Voltage: ±100ppm/ C Only Three External ponents are needed: an Inductor, a Schottky Diode and an Output Filter Capacitor. High Power Conversion Efficiency: 85% Low Quiescent Current Drawn from Power Source: <7u A o supply voltage as low as 0.8V, and capable of delivering maximum 200m A output current at 3.3V output with 1.8V input voltage.
Quiescent current drawn from power source is as low as 7u A. 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...
