HIGH EFFICIENCY, LOW SUPPLY CURRENT, MULTI-FUNTION STEP-UP DC/DC CONTROLLER

BL8530C

SELECTION GUIDE：

BL8530C

--XX X XX

OUTLINE：

The BL8530C series are CMOS-based

PFM step-up DC-DC Controller with low supply

current and high output voltage accuracy.

Quiescent current drawn from power source is

as low as 6uA. It is capable of delivering

500mA output current at 4.0V output with 2V

input Voltage. Only four external components

are necessary: An inductor, a Schottky diode,

an output filter capacitor and a NMOSFET or a

NPN transistor All of these features make

BL8530C series be suitable for the portable

devices, which are supplied by a single battery

to four-cell batteries.

BL8530C has a drive pin (EXT) for

external transistor. So it is possible to load a

large output current with a power transistor

which has a low saturation voltage.

BL8530C integrates stable reference

circuits and trimming technology, so it can

afford high precision and low temperature-drift

coefficient of the output voltage.

BL8530C is available in SOT-23-3 and

SOT-23-5 packages which are PB free. And in

SOT-23-5 the device can be switch on or off

easily by CE pin, to minimize the standby

supply current.
