Capacitor Selection
For the input bypass capacitors, high quality X5R or X7R
types should be used. Make sure the voltage capability of
the part is adequate.
Output Diode Selection
The rectifying diode(s) should be low capacitance type
with sufficient reverse voltage and forward current rat-
ings. The peak reverse voltage that the diode(s) will see is
approximately:
VV
N V
PK R
OUT
IN
=+
()
The peak current of the diode is simply:

(LT3484-1)
For the circuit of Figure 6 with VBAT of 5V, VPK-R is 371V
and IPK-SEC is 137mA. The GSD2004S dual silicon diode is
recommended for most LT3484-0/LT3484-1/LT3484-2
applications. Another option is to use the BAV23S dual
silicon diodes. Table 3 shows the various diodes and
relevant specifications. Use the appropriate number of
diodes to achieve the necessary reverse breakdown
voltage.
