YB1300S
Switched Capacitor Boost Converter 5V/4.5V
Description
The YB1300S is a switched capacitor
DC/DC boost converter that produces a
regulated 5V output. The input voltage
range is from 2.7V to 5.0V that makes the
YB1300S ideally for a single cell Li-Ion
battery source.
The YB1300S works well for step-up
applications without the need for an
inductor. The 1MHz switching frequency
allows the use of small SMD capacitors.
The YB1300S provides thermal protection,
short-circuit current limit protection. In
order to prevent in-rush current effectively,
it provides automatic soft-start. The
shutdown current is less than 0.1μA. The
YB1300S is available in a 6-pin SOT23
package.

the device is automatically reenabled.
Continuously running the regulator into
thermal shutdown can degrade reliability.
Shutdown Mode
A control pin on the regulator can be used
to place the device into an energy-saving
shutdown mode. In this mode, the output is
disconnected from the input.
Layout Consideration
Due to large transient currents and high
switching frequency produced by the
YB1300S, careful consideration of PCB
layout is necessary. In order to minimize
both input and output ripple, keep the
capacitors as close as possible to the
regulator using short, direct circuit traces. A
ground plane and short connections to all
capacitors will improve performance and
ensure proper regulation under all
conditions. Figure 4 and Figure 5 show the
recommended layout configuration.
