DESCRIPTION
The A7501 Series are VFM Step-Up DC-DC ICs with ultra ow supply current by CMOS process and suitable for use with battery-powered instruments.
The A7501 IC consists of and oscillator, a VFM control circuit, a driver transistor (LX switch), a reference voltage unit, and 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 A7501 IC with only three external components. A protection circuit turns off the built-in MOSFET when the voltage at the CONT pin exceeds the limit to prevent it from being damaged. A7501 with a fixed duty ratio of 75 (Lower Output Voltage) or 88 (Higher Output Voltage).
A7501 is available in SOT-23, SOT-25 and SOT89-3 packages.
FEATURES
? Minimal Number of External Components, Only an Inductor (AiT-WSS0703-220M), a Diode (AiT-SM140A), and a Capacitor.
? Ultra Low Input Current: 6.5μA at no load
? 1.8V to 5.0V Output Voltage
? ±2 High Output Voltage Accuracy
? Low Ripple and Low Noise
? Low Start-Up Voltage, 0.9V at 1mA
? Duty ratio: 77 Built-in fixed-type PFM controller
? Available in SOT-23, SOT-25 and SOT89-3 packages
APPLICATION
? Power Source for Battery-Powered Equipment
? Power Source for Camera, Camcorder, VCT, PDA, Pager, Electronic Data Bank, Hand-Held Communication Equipment and Audio Equipment.
? Power Source for Applications which require higher voltage than that of batteries used in the appliances.
