1D8A_1.5UP Series
1W - Single Output - Fixed Input - Isolated & Unregulated
MINIATURE DIP PACKAGE
DC-DC Converter
1 Watt
The 1D8A_1.5UP series are specially designed for applications where an isolated
Efficiency up to 80%
Miniature SIP package
Single output voltage
1500VDC Isolation
Temperature range:
-40°C~+105°C
Industry standard pinout
voltage is required in a distributed power supply system.
Short circuit protection (SCP)
RoHS compliance
No external component
required
These products apply to:
1) Where the voltage of the input power supply is stable
(voltage variation: 10ꢀ%in)ꢁ
PCB mounting
2) Where isolation between input and output is necessary
(isolation voltage ≤1500%DC)ꢁ
3) Where the output voltage regulation and the ripple & noise of the output
voltage is not strictly required.
Typical application: digit circuit conditionꢁ normal low-frequency artificial
circuit conditionꢁ relay drive circuit and data switching circuit condition, etc.
