Functional Description
Overview
The
technology to provide high switching frequency,
while also maintaining high efficiency.
Packaged in a 4 mm x 6 mm x 1.1 mm
the EN5339QI provides a high degree of flexibility
in circuit design while maintaining a very small
footprint. High switching frequency allows for the
use of very small MLCC input and output filter
capacitors.
The converter uses Type III voltage mode control to
provide high noise immunity, low output impedance
and excellent load transient response.
POK monitors the output voltage and signals if it is
within ±10% of nominal. Protection features include
under voltage lockout (UVLO), over current
protection, short circuit protection, and thermal
overload protection.

Stability
Conditions
The EN5339QI utilizes an internal compensation
network and is designed to provide stable operation
over a wide range of operating conditions. To
improve transient performance or reduce output
voltage ripple with dynamic loads you have the
option to add supplementary capacitance to the
output.
Soft Start
The EN5339QI has an internal soft-start circuit that
controls the ramp of the output voltage. The control
circuitry limits the V
safe for the Power MOSFETS and the integrated
inductor.
The EN5339QI has a constant startup up time
which is independent of the VOUT setting. This
means that the output slew rate is a function of the
output voltage setting. The startup time is given in
