PFM STEP-UP DC/DC CONVERTER WITH HIGH EFFICIENCY AND LOW NOISE
BL8530
SELECTION GUIDE:
BL8530
--XX X XX
OUTLINE:
The BL8530 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
BL8530 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, BL8530 is well considerated in circuit
design and manufacture. So that the interferer
to other circuits by the device is reduced
greatly.
BL8530
integrates
stable
reference
circuits and trimming technology, so it can
afford high precision and low temperature-drift
coefficient of the output voltage.
BL8530 is available in SOT-89-3 、
SOT-23-3 and SOT-23-5 packages which is PB
free. And in 5-pin packages, such as
SOT-23-5, the device can be switch on or off
easily by CE pin, to minimize the standby
supply current.
FEATURES:
Deliver 200mA at 3.3V Output voltage
with 1.8V input Voltage
Low start-up voltage (when the output
current is 1mA)--------------------------0.8V
The converter output voltage can be
adjusted from 2.5V~6.0V(In 0.1V step).
Output voltage accuracy -----------±2%
Low temperature-drift coefficient of the
output voltage------------------
±100ppm/℃
Only three external components are
necessary: An inductor, a Schottky diode
and an output filter capacitor
High power conversion efficiency---85%
Low quiescent current drawn from power
source------------------------------------- <7uA
APPLICATIONS
Power source for PDA、DSC、MP3
Player、electronic toy and wireless mouse
Power source for a single or dual-cell
battery-powered equipments
Power source for LED
