KB2301

Step-Up DC-DC Converter

Features

General Description

yꢀ400KHz Maximum Operation Frequency

yꢀ2.0V to 5.0V Output Voltage With 0.1V Step

yꢀLow Start-up Voltage: 0.8V at 1mA

yꢀ2% Output Voltage Accuracy

yꢀUp to 88% Efficiency

The kB2301 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.

yꢀOutput 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.

yꢀLow Ripple and Low Noise

yꢀOutput Current Extendable by External

Switch

Enable pin (EN) is also provided so that the

circuit can be powered down.

Applications

yꢀPower source for applications where a higher

voltage than the battery voltage is required

Ordering Information

yꢀOne to three cell battery devices

; ; ; ;

ꢀꢁꢂꢃ

yꢀPower source for cameras, camcorders,

VCRs, PDAs, pagers and hand held

communication instrument

Package Type:

T: SOT-23-3

F: SOT-23-5

E: SOT-89

Output Voltage:

20: 2.0V

21: 2.1V

49: 4.9V

50: 5.0V

External switch

E: use external switch

L: use internal switch
