The PT6420 series from Power
Trends is a high performance +5V to
+3.3V, 3Amp family of 14-Pin SIP
(Single In-line Package) Integrated
Switching Regulators (ISRs). Only
two external capacitors are required
for proper operation.
Please note that this product does
not include short circuit protection.
