2S7A_1.5UP Series
2W - Dual/Single Output DC-DC Converter - Fixed Input - Isolated & Unregulated
DC-DC Converter
2 Watt
The 2S7A_1.5UP series are specially designed for applications where a group of
polar power supplies are isolated from the input power supply in a distributed
power supply system on a circuit board.
High efficiency up to 86%
1.5kVDC Isolation
Miniature SIP package
High power density
Temperature range:
-40°C ~ +105°C
Short circuit protection (SCP)
No external component
required
Industry standard pinout
RoHS Compliance
These products apply to:
1) Where the voltage of the input power supply is stable
(voltage variation: 10ꢀ%in)ꢁ
2) Where isolation between input and output is necessary
(isolation voltage ≤1500%DC)ꢁ
3) Where the output voltage regulation is not strictly required.
Typical application: digit circuit conditionꢁ normal low-frequency artificial circuit
conditionꢁ relay drive circuit and data switching circuit.
