Description
General Description
The RT9261 Series are VFM Step-up DC/DC ICs with ultra low supply current by CMOS process and suitable for use with battery-powered instruments.
The RT9261 IC consists of an oscillator, a VFM 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 RT9261 IC with only three external components.
Features
• Minimal Number of External Components ( Onl an Inductor, a Diode, and a Capacitor)
• Ultra Low Input Current ( 5μA at Switch Off)
• ± 2% High Output Voltage Accuracy
• Low Ripple and Low Noise
• Low Start-up Voltage, 0.85V at 1mA
• 75% Efficiency with Low Cost Inductor
• +50 ppm/ °C Low Temperature-Drift
• SOT-89 and SOT-23-5 Small Packages
• RoHS Compliant and 100% Lead (Pb)-FreeApplications
• Power source for battery-powered equipment
• Power source for cameras, camcorders, VCRs, PDAs, pagers, electronic data banks, and hand-held communication equipment
• Power source for applications, which require higher voltage than that of batteries used in the appliances
Alternatives

Functional Equivalent (FE) materials, including Fused Filament Fabrication (FFF) form, assembly, and functionally compatible substitute materials.
