DESCRIPTION
FEATURES
A7531 series are CMOS-based PFM step-up DC-DC● Deliver 500mA at 4.0V output voltage with 2V Controller with low supply current and high output voltage accuracy. Quiescent current drawn from
● power source is as low as 6uA. It is capable of delivering 500mA output current at 4.0V output with 2V
● input voltage. Only four external components are necessary: An inductor, a schottky diode, an output
● filter capacitor and a NMOSFET or a NPN transistor. All of these features make A7531 series be suitable for
● input Voltage The controller 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 four external components are necessary: the portable devices, which are supplied by a single An inductor, a schottky diode, an output filter battery to four-cell batteries. So
● it is possible to load a large output current with a
● power transistor which has a low voltage dropout.
