EC9206 Datasheet PDF

E-CMOS EC9206

The EC9206 is a compact PFM step-up DC/DC converter that operates from an input voltage as low as 1.0 Volt. The low start-up input voltage makes EC9206 specially designed for portable devices from one or two cell battery, delivering up to 180mA load current at VIN=1.5V VOUT=3.3V. The EC9206 features a minimum off-time, current -limited, PFM control scheme which combines the advantages of PWM (higher output power and efficiency) and those of traditional PFM (ultra-low quiescent current).

APPLICATIONS

Typical efficiency for EC9206 is 85% when VIN>=2.0V VOUT=3.3V ILOAD=1~60mA. Potential applications include low powered consumer products and battery powered portable products. The internal 0.6 ohm low turn-on resistance NMOS power switch provides stable and high-efficiency operation over a board load current range. Chip enable feature is provided for SOT-23-5 package to power down the device. The EC9206 devices are available in both SOT-89 and SOT-23-5 packages with 6 standard regulated output voltages. z PDA z DSC z MP3 Player z Electronic Games z Camcorders z Portable Devices...
