LPS60-12

The LPS60-12 features low ripple and noise for sensitive applications: Typical ripple is 120mV peak-to-peak at full load; Noise is typically less than 50mV peak-to-peak high-frequency; Combined ripple and noise is specified as 150mV peak-to-peak maximum; Measurements are made with 20MHz bandwidth limit and proper probing technique. For applications requiring lower ripple: Add external output capacitors (100-1000uF); Use a small LC filter for additional attenuation; Consider linear post-regulation for noise-sensitive circuits. The switching frequency (typically 65kHz) is low enough to minimize switching noise while maintaining good efficiency. Ripple increases slightly at higher input voltages and decreases at lighter loads.

For noise-sensitive applications, add external filtering or consider linear post-regulation.

The LPS60-12 provides excellent line regulation to maintain stable output across the input voltage range: Line regulation is +/-0.5% typical from low line to high line; This means the 12V output varies by less than 60mV across the entire 85-264VAC input range; Load regulation is +/-1% from no load to full load; Combined regulation is better than +/-2% under all operating conditions. The tight regulation is achieved through feedback control that continuously adjusts the switching to maintain output voltage. For applications requiring even tighter regulation: Add a linear post-regulator for the most sensitive circuits; Ensure adequate input capacitance to prevent voltage droop under load transients; Consider remote sense if available on specific models. The excellent regulation makes this module suitable for powering sensitive industrial controls and communication equipment.

For applications requiring extremely tight regulation, consider adding linear post-regulation for critical circuits.

The LPS60-12 maintains high efficiency across the load range: Peak efficiency of 89% occurs at approximately 75% load (45W); At 100% load (60W): 88% efficiency; At 50% load (30W): 87% efficiency; At 25% load (15W): 84% efficiency; At 10% load (6W): 78% efficiency. The efficiency curve is optimized for industrial applications where the module typically operates at moderate to high loads. The high efficiency minimizes heat generation, allowing operation at higher ambient temperatures and reducing cooling requirements. For applications with significant light-load operation, consider the impact of lower efficiency on overall system power consumption. The module meets modern energy efficiency requirements including EuP and Energy Star standby power limits.

For applications with varying load conditions, verify efficiency at your typical operating points to calculate thermal requirements.

The LPS60-12 can be mounted on a heatsink or metal chassis for improved thermal performance: The encapsulated package has a thermally conductive base that can be attached to a heatsink; Thermal interface material (TIM) should be used for good thermal contact; Mounting torque should not exceed 0.5 Nm to avoid package damage; Heatsink mounting can extend the operating temperature range or increase maximum output power. For chassis mount applications: The module can be mounted to a metal enclosure for heatsinking; Ensure adequate clearance for airflow around the module; Consider thermal vias in the PCB for additional heat spreading. The thermal resistance from case to ambient is significantly reduced with proper heatsinking, allowing higher power output or operation at higher ambient temperatures.

For high-temperature or high-power applications, consider heatsink mounting to improve thermal performance.

The LPS60-12 provides good transient response for dynamic loads: Output voltage deviation is typically +/-5% for a 50% load step; Recovery time is less than 5ms to return to within 1% of nominal; The internal control loop is optimized for typical industrial load profiles; For applications with very fast load transients, additional output capacitance can improve response. The transient response is characterized by: Initial voltage dip or rise based on load step direction; Recovery overshoot typically less than 2%; Settling to within regulation within 5ms. For applications with repetitive load transients: Ensure output capacitors have low ESR for best performance; Consider the RMS current rating of capacitors under ripple conditions; Multiple smaller capacitors may perform better than single large capacitor. The module's transient response is suitable for most industrial control and motor drive applications.

For applications with large or fast load transients, verify transient response meets your system requirements.

The LPS60-12 has low leakage current suitable for most applications: Touch current (leakage to earth) is less than 0.5mA at 264VAC; This meets the requirements for Class I equipment with protective earth; For medical applications requiring lower leakage, special versions are available; Leakage current varies with input voltage and is highest at maximum input voltage. The leakage current specification includes: Capacitive coupling through EMI filter capacitors; Small resistive leakage through insulation; Measured per IEC 60990 with specified measuring network. For applications with very strict leakage requirements: Consider medical-grade versions with enhanced isolation; Implement additional isolation transformers if required; Verify compliance with specific application standards (medical, laboratory equipment). The standard LPS60-12 meets industrial and commercial equipment requirements.

For medical or sensitive applications, verify leakage current meets your specific safety standard requirements.
