Note: 1. An input line fuse is recommended for use.
2. External input capacitance required. See Input Ripple Current test measurement setup on Figure 1.
3. Refer to Figure 2 for output ripple measurement setup.
4. Appropriate Thermal Derating applies. See Figure 6.
5. Over current and over voltage protections are all in auto recovery mode. The converter will shutdown
during fault condition then will attempt to auto restart.
6. Output of the module will be terminated once the operating temperature reaches the OTP threshold.
Normal operation resumes once the temperature falls below the OTP threshold.
