This EVM is designed to cover as many applications as possible. For some more specific applications, the circuit
can be simpler. The table below gives some recommendations.
Table 2. EVM Application Recommendations
<3–A OUTPUT CURRENT
Change Q1/Q2 and Q3/Q4 to dual pack MOS-
FET, IRF7311 to reduce the cost.
5V INPUT VOLTAGE
DIODE VERSION
Change C1 to low profile capacitor
Sanyo 10TPB220M (220

F, 10 V)
Or 6TPB330M (330
μ
F, 6.3 V)
Remove R12
Remove Q2 and Q4 to reduce the cost.
