DA2032-AL_ low-profile transformer use in a 300 V, 3 A charging circuit
Description:
These surface mount flyback transformers were developed
for use with Linear Technology LT3750 Capacitor
Charger Controller. DA2033-AL and DA2034-AL are
also specified for the LT3751 Controller. They have a
smaller footprint than other transformers designed for
this application.
These low-profile transformers feature 1500 Vrms, one
minute winding to winding isolation and 750 Vrms winding
to core isolation. They are designed to operate with an
input range of 3 – 24 V and to charge a capacitor to 300 V.
They are shown on the Linear Technology LT3750 application
note for use in a 300 V, 3 A charging circuit
(DA2032); a 300 V, 6 A charging circuit (DA2033); and a
300 V, 9 A charging circuit (DA2034).
Core material Ferrite
Terminations RoHS compliant tin-silver over tin over nickel over
phos bronze. Other terminations available at additional cost.
