Description
The RT9261-27PX is a VFM Step-up DC/DC IC designed for battery-powered instruments. It is constructed with an oscillator, a VFM control circuit, a driver transistor, a reference voltage unit, an error amplifier, resistors for voltage detection, and a LX switch protection circuit. With only three external components, this IC can achieve low ripple and high efficiency step-up DC/DC conversion.
Specifications and features
- Minimal Number of External Components (Inductor, Diode, and Capacitor)
- Ultra Low Input Current (5μA at Switch Off)
- High Output Voltage Accuracy (±2%)
- Low Ripple and Low Noise
- Low Start-up Voltage (0.85V at 1mA)
- 75% Efficiency with Low Cost Inductor
- Low Temperature-Drift (+50 ppm/°C)
- Available in SOT-89 and SOT-23-5 Small Packages
