Table 2. Recommended Capacitors
Capacitor Selection
Input and output capacitors should have low ESR for best
efficiency. Recommended capacitors include AVX TPS
series, Sprague 595D series, and Sanyo OS-CON. The
output capacitor’s ESR determines the high frequency
ripple amplitude. A 100
µF capacitor is the minimum rec-
ommended for a 5V output. Higher output voltages can use
lower capacitance values. For example, a 12V output can
use a 33
µF or 47µF capacitor. The VIN pin of the LT1303
should be decoupled with a 47
µF or 100µF capacitor at the
pin. When driving a transformer, an additional decoupling
network of 10
Ω and 0.1µF ceramic is recommended as
shown in Figure 10.
Diode Selection
The LT1303’s high switching speed demands a high speed
rectifier. Schottky diodes are preferred for their low for-
ward drop and fast recovery. Suitable choices include the
1N5817, MBRS120LT3, and MBR0520LT1. Do not use
signal diodes such as 1N4148. They cannot carry 1A
current. Also avoid “general-purpose” diodes such as
1N4001. These are far too slow and are unsuitable for any
switching regulator application. For high temperature
applications a silicon diode such as the MUR105 will have
less leakage.
