Safety Approvals —Pending
compatible with Power Trends’ popular
PT4200 series. The PT4210 series has
improved load regulation over the
PT4200, and is a compatible alternative
for both new and existing designs.
Applications include Telecom and
Datacom systems where both board
space and height are a premium.
The PT4210 series is offered in both
through-hole or SMD-DIP package
types with single non-adjustable output
voltages of 3.3V, 5V, and 12V.
Description
The PT4210 series of low-power
isolated DC-DC converters are pin-

Notes:
(1) See SOA curves or consult the factory for the appropriate derating.
(2) The maximum output capacitance must not exceed 150µF for the PT4212, 120µF for the PT4213, and 47µF for the PT4214.
