DESCRIPTION
A7530 is PVM Step-Up DC/DC IC with ultra low supply current by CMOS process and suitable for use with battery-powered instruments.
The A7530 IC consists of an oscillator, a PFM control circuit, a driver transistor (LX switch), a reference voltage unit, an error amplifier, resistors for voltage detection, and a LX switch protection circuit. A low ripple and high efficiency step-up DC/DC converter can be constructed of this A7530 IC with only three external components.
Output voltage can be selectable in the range from 2.5V to 6.0V, The A7530 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 4uA. Packages with EN (chip enable) pin are also available which can reduce the IC power consumption during stand-by mode.
The A7530 is available in SOT-23, SOT-25 and SOT89-3 packages.
