MICRO POWER STEP-UP DC-DC CONVERTER
AP3015/A
General Description
Features
The AP3015/A are Pulse Frequency Modulation
(PFM) DC/DC converters. These two devices are functionally equivalent except the switching current limit.
The AP3015 is designed for higher power systems
with 350mA current limit, and the AP3015A is for
lower power systems with 100mA current limit.
·
·
·
The AP3015/A feature a wide input voltage. The operation voltage is ranged from 1.2Vto 12V (1V to 12V
for AP3015A). A current limited, fixed off-time control scheme conserves operating current, resulting in
high efficiency over a broad range of load current.
They also feature low quiescent current, switching current limiting, low temperature coefficient, etc.
·
·
·
Fewer tiny external components are required in the
applications to save space and lower cost.
Furthermore, to ease its use in differnet systems, a disable terminal is designed to turn on or turn off the chip.
·
The AP3015/A are available in SOT-23-5 package.
