IN
BOOST
WAKE
SLEW
Function
Voltage Regulator Output 1; 5V output; acts as the reference
for the voltage trackers.The SPI and window watchdog logic is
supplied from this voltage. For stability a ceramic capacitor of
470nF to GND is sufficient.
and pin Bootstrap, the capcitance value should be 2% of the
Buck converter output capacitance
Switch Output; connect both pins externally through short lines
directly to the cathode of the catch diode and the Buck circuit
inductance.
Supply Voltage Input; connect both pins externally through
short lines to the input filter/the input capacitors.
Boost Input; for switching loss minimization connect a diode
(cathode directly to boost pin) in series with a 100nF ceramic
capacitor to the IN pin and from the anode of the diode to the
buck converter output a 22 resistor. Recommended for 42V
applications. In 12/24V applications connect boost directly to IN.
Wake Up Input; a positive voltage applied to this pin turns on
the device
Slew control Input; a resistor to GND defines the current slope
in the buck switch for reduced EME
