260KHz Maximum Operation Frequency
The CYT2606 Series are PFM step-up
DC-DC converters with very low ripple noise
due to the high operation frequency. The
maximum operation frequency is 260KHz.
2.0V to 5.0V Output Voltage With 0.1V Step
Low Start-up Voltage: 0.8V at 1mA
±2.5% Output Voltage Accuracy
Up to 88% Efficiency
Only three components are required to
realize the conversion from the battery voltage
to a selected output voltage.
Output current: 300mA at 2.5V input, 3.3V

Low Ripple and Low Noise
Output Current Extendable by External
Switch
A driver pin (EXT) is provided for driving
external power transistor to extend the output
current capability where large current is
required. Enable pin (EN) is also provided so
that the circuit can be powered down.
Applications
■
Power source for applications where a higher
voltage than the battery voltage is required
One to three cell battery devices
Power source for cameras
