APPLICATIO S I FOR ATIO
skipping using a 1k resistor from FB to GND. The photo
in Figure 3b details circuit operation driving three white
LEDs at a 0.2mA load. Peak inductor current is less
than 30mA.
Inductor Selection
A 22 μ H inductor is recommended for most LT3465 appli-
cations. Although small size and high efficiency are major
concerns, the inductor should have low core losses at

Table 1. The efficiency comparison of different inductors
is shown in Figure 4a. A 22 μ H or 10 μ H inductor is recom-
mended for most LT3465A applications. The inductor

The small size of ceramic capacitors makes them ideal for
408-573-4150

LT3465 and LT3465A applications. X5R and X7R types are
recommended because they retain their capacitance over
wider voltage and temperature ranges than other types
such as Y5V or Z5U. A 1 μ F input capacitor and a 0.22 μ F
output capacitor are sufficient for most LT3465 and
LT3465A applications.
