AX5110
Step-up PFM DC/DC Converter
GENERAL DESCRIPTION
The AX5110 is a Pulse Frequency Modulation (PFM) DC/DC converter. It is Low
quiescent current 30uA and shutdown current less 1uA. The AX5110 feature a wide
input voltage. The operating voltage is ranged from 1.2V to 12V. It also feature low
quiescent current, switching current limiting, low temperature coefficient.
Smaller package size and fewer tiny external components are required in the
application to save space and lower cost. AX5110 is available in SOT-23-5L package.
FEATURES
- Input voltage: 1.2V to 12V
- Low Quiescent Current: 17uA(typ.)
- Low Saturation Voltage : 200mV typical at 300mA
- 350mA typical switching current limiting
- High output voltage : up to 34V
- Low Profile SOT-23-5 Pb-Free Packaging

PCB layout guide
When laying out the PC board, the following suggestions should be taken to
ensure proper operation of the AX5110. These items are also illustrated graphically in
below.
1. The power traces, including the GND trace, the SW trace and the VCC trace should
be kept short, direct and wide to allow large current flow. Put enough multiply-layer
pads when they need to change the trace layer.
2. Connect the input capacitor C1 to the VCC pin as closely as possible to get good
power filter effect.
3. Do not trace signal line under inductor.
