CYT2606L
PFM Step-Up DC-DC Converter
Features
General Description
ꢀ400KHz Maximum Operation Frequency
ꢀ2.0V to 5.0V Output Voltage With 0.1V Step
ꢀLow Start-up Voltage: 0.8V at 1mA
ꢀ±2% Output Voltage Accuracy
ꢀUp to 88% Efficiency
The CYT2606L Series are PFM step-up DC-DC
converters with very low ripple noise due to the
high operation frequency. The maximum
operation frequency is 400KHz.
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
output
A driver pin (EXT) is provided for driving
external power transistor to extend the output
current capability where large current is required.
ꢀLow Ripple and Low Noise
ꢀOutput Current Extendable by External
Switch
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
Ordering Information
ꢀOne to three cell battery devices
ꢀPower source for cameras, camcorders,
VCRs, PDAs, pagers and hand held
communication instrument
