Description
The EVAL5985 demonstration board provides the
design engineer with a fully functional step-down
switching regulator with an output current of up to
2 A. The board integrates STMicroelectronics’
L5985 step-down switching regulator, together
with all the external components required for a
typical application.
The rated voltage of the input capacitor and the
Schottky diode rectifier repetitive peak reverse
voltage are both 25 V, making the board capable
of covering the entire 2.9 V - 18 V input voltage
range of the L5985 device.
The board features an external resistor divider
(R1 and R2) designed for an output voltage
of 3.3 V.
The output voltage can be set to a level from 0.6 V
up to the rated voltage of the output capacitor
(16 V).
The compensation network on the demonstration
board allows the use of MLCC as output filter to
keep the loop stable. The inductor saturation
current and forward current of the Schottky diode
are within the current limit values.
The switching frequency on the demonstration
board is set to 500 kHz by means of the R5
resistor connected to pin Fsw.
