BL8530C
HIGH EFFICIENCY, LOW SUPPLY CURRENT, MULTI-FUNTION STEP-UP DC/DC CONTROLLER
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.
