Functional Description
The EN5322 leverages advanced CMOS
technology
to
provide
high
switching
frequency, while also maintaining high
efficiency.
Packaged in a 4 mm x 6 mm x 1.1 mm QFN,
the EN5322 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 voltage mode control to
provide high noise immunity, low output

impedance and excellent load transient

components are needed for most applications.
Output voltage is chosen from one of seven
preset values via a three-pin VID voltage select
scheme. An external divider option enables the
selection of any output voltage
≥
0.6 V. The
VID pins can be toggled dynamically to
implement glitch-free dynamic voltage scaling
between any two VID preset values.
POK monitors the output voltage and signals if
it is within ±10% of nominal. Protection
