1D14B Series
1W Single/Dual Output - Fixed Input - Isolated & Unregulated
DIP PACKAGE
DC-DC Converter
1 Watt
The 1D14B series is specially designed for applications where an isolated voltage
is required in a distributed power supply system.
These products apply to:
1) Where the voltage of the input power supply is fixed (voltage variation ≤ 10ꢀ)
2) Where isolation is necessary between input and output
(isolation voltage =1500VDC)
High Efficiency up to 81%
DIP Package
Industry Standard Pinout
UL94-V0 Package
1.5KVDC Isolation
Short circuit protection (SCP)
Temperature Range:
-40°C~+105°C
No External Component

Note:
1. Operation under minimum load will not damage the converter; However, they
may not meet all specification listed, and that will reduce the life of product.
2. All specifications measured at Ta=25°C, humidity<75ꢀ, nominal input voltage
and rated output load unless otherwise specified.
3. In this datasheet, all the test methods of indications are based on corporate
standards.
