APPLICATIONS INFORMATION - POWER MANAGEMENT IC INTEGRATION
Inductor
The buck converter is optimized to work with an
inductor in the range of 10uH to 100uH. 10uH is
adequate for space-limited applications, but 100uH
may provide greater efficiency, particularly as the ratio
between input and output voltage increases (see
LTC3588 datasheet). Choose an inductor with a DC
current rating greater than 350mA. Lower DCR
inductors can impact the efficiency of the buck
converter.
V IN2 and CAP Capacitors
A 1uF capacitor should be connected between V IN and
CAP and a 4.7uF capacitor should be connected
between V IN2 and GND. These capacitors hold up the
internal rails during buck switching and compensate
the internal rail generation circuits. In applications
where the input source is limited, to less than 6V, the
CAP pin can be tied to GND and the V IN2 pin can be tied
to V IN . In this scenario, a 5.6V Zener diode can be
used to clamp VIN.
