Frequently Asked Questions
What input capacitor is recommended for URB2415YMD-20WR3?
URB2415YMD-20WR3 input capacitor recommendations: Minimum capacitor is 10µF low ESR electrolytic or ceramic capacitor. Recommended value is 22µF to 47µF for stable operation. Capacitor type should be Low ESR electrolytic, tantalum, or ceramic (X5R/X7R). Voltage rating should be at least 1.5x maximum input voltage (use 50V or 63V for 36V max input). Place capacitor close to input pins to minimize inductance.
Use 22-47µF low ESR capacitor close to input pins. Contact us for specific application recommendations.
Can URB2415YMD-20WR3 start at 9V input with full load?
URB2415YMD-20WR3 is guaranteed to start at 9V input at full load (20W). The converter starts when input exceeds undervoltage lockout (UVLO) threshold. UVLO hysteresis is typically 0.5V to prevent oscillation at threshold. For battery applications, ensure battery can deliver required current at low voltage and use adequate wire gauge to minimize voltage drop.
Guaranteed to start at 9V with full load. Ensure input source can deliver required current at minimum voltage.
What is the ripple and noise specification?
The URB2415YMD-20WR3 has typical output ripple of 50mV peak-to-peak at nominal input and full load. Ripple varies with input voltage and load conditions. For applications requiring lower ripple, add external output capacitors or use LC filters. The switching frequency is 300kHz which helps minimize ripple while maintaining efficiency.
Standard ripple suitable for most applications. Add external filtering for noise-sensitive circuits.
Can I use multiple converters in parallel?
URB2415YMD-20WR3 is not designed for direct parallel operation as it does not include active current sharing. For higher power requirements, use a single higher power converter or distribute loads among multiple converters. Each converter should have its own input and output capacitors.
Not recommended for parallel operation. Use higher power single converter or separate load distribution.
What is the isolation capacitance?
The URB2415YMD-20WR3 has typical isolation capacitance of 20pF. Low isolation capacitance is important for applications with high dv/dt on the input side to minimize common-mode current coupling through the isolation barrier. This makes the converter suitable for noisy industrial environments.
