PFM Step-up DC/DC Converter With

High Efficiency And Low Noise

KX8530

Outline

The KX8530 series are CMOS-based PFM step-up

DC-DC Converter. The converter can start up by

supply voltage as low as 0.8V, and capable of

delivering maximum 200mA output current at 3.3V

output with 1.8V input Voltage. Quiescent current

drawn from power source is as low as 7uA. All of

these features make KX8530 series be suitable for

the portable devices, which are supplied by a single

battery to four-cell batteries.

To reduce the noise caused by the switch

regulator, KX8530 is well considerated in circuit

design and manufacture. So that the interferer to

other circuits by the device is reduced greatly.

KX8530 integrates stable reference circuits and

trimming technology, so it can afford high precision

and low temperature-drift coefficient of the output

voltage.

KX8530 is available in SOT-89

SOT-23 and

SOT-153 packages which is PB free. And in 5-pin

packages, such as SOT-153, the device can be

switch on or off easily by CE pin, to minimize the

standby supply current.
