1 High efficiency up to 83% for energy-saving operation

2 4000VDC isolation to ensure safety and reduce interference in distributed systems

3 Compact SIP package for easy integration into space-constrained designs

4 International standard pinout for compatibility with common PCB layouts

5 Wide ambient temperature range: -40°C to +105°C, suitable for harsh environments

6 RoHS and CE compliant, meeting international environmental and safety standards

7 Short circuit protection (SCP) to prevent damage from unexpected load faults

8 Low weight of 2.1g, ideal for lightweight applications

9 Various input/output voltage combinations (e.g.,3.3V/5V/9V/12V/15V inputs and outputs) to fit diverse system requirements

10 Line regulation performance adapts to input voltage changes (±10%)

11 Switching frequency ranges from 120kHz to180kHz depending on input voltage

1 Distributed power supply systems requiring isolated voltage conversion

2 Digital circuits (e.g., microcontrollers, logic gates) in consumer electronics or industrial devices

3 Low-frequency analog circuits (e.g., sensor interfaces, signal amplifiers) needing stable power

4 Relay-driven circuits in industrial control systems (e.g., PLC modules, automation equipment)

5 Applications where input voltage stability is within ±10% variation

6 Setups where output voltage regulation and ripple noise are not critical

7 Harsh environment applications (e.g., outdoor sensors, automotive auxiliary systems) due to wide temperature tolerance

8 Space-constrained designs (e.g., portable devices, compact embedded systems) using SIP package

1 Operation under minimum load will not damage the converter but may not meet specified performance parameters

2 All specifications are measured at 25°C ambient temperature unless otherwise noted

3 Storage temperature range: -50°C to +105°C; avoid exceeding this range to prevent component degradation

4 Storage humidity should be ≤95% (non-condensing) to protect against moisture damage

5 Case temperature above ambient should not exceed30°C to ensure long-term reliability

6 Follow the recommended footprint for PCB mounting to ensure proper electrical connection and heat dissipation

7 Refer to the tolerance envelope curve for output voltage variations with different load currents

8 Prolonged short circuits should be avoided even though short circuit protection is included

9 Specifications are subject to change without prior notice; contact technical support for specific application requirements

10 Use within the maximum input voltage rating (e.g.,3.6V for3.3V input models) to prevent overvoltage damage
