1,500 VDC Isolation
6 Pin DIP Package
Low-Profile (8mm)
Pin-compatible with PT4200 Series
No External Components Required 2
Safety Approvals —Pending
Description
The PT4210 series of low-power
isolated DC-DC converters are pin-
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.
