RT9261B-50PX - Brand New RICHTEK IC Chips
-
Description
The RT9261B-50PX is a VFM Step-up DC/DC converter IC from the RT9261B Series. It is designed with ultra low supply current by CMOS process, making it suitable for use with battery-powered instruments. The IC features 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. With only three external components, a low ripple and high efficiency step-up DC/DC converter can be constructed using the RT9261B-50PX.
Specifications and features
- Minimal Number of External Components (Only an Inductor, a Diode, and a Capacitor)
- Ultra Low Input Current (6.5μA at Switch Off)
- Capable of Supplying 50mA Output Current with Internal Switch
- ± 2% Output Voltage Accuracy
- Low Ripple and Low Noise
- Low Start-up Voltage, 0.8V at 1mA
- 80% 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)-Free
Application Scenarios
The RT9261B-50PX is commonly used as a power source for battery-powered equipment such as cameras, camcorders, VCRs, PDAs, pagers, electronic data banks, and hand-held communication equipment. It can also be used as a power source for appliances that require higher voltage than that of batteries used in the appliances.
