Packaging & ESD

Industry-standard static shielding packaging is used for electronic components.Anti-static, light-transparent materials allow easy identification of ICs and PCB assemblies.
The packaging structure provides electrostatic protection based on Faraday cage principles.This helps protect sensitive components from static discharge during handling and transportation.


All products are packed in ESD-safe anti-static packaging. Outer packaging labels include part number, brand, and quantity for clear identification. Goods are inspected prior to shipment to ensure proper condition and authenticity.

ESD protection is maintained throughout packing, handling, and global transportation. Secure packaging provides reliable sealing and resistance during transit. Additional cushioning materials are applied when required to protect sensitive components.

Frequently Asked Questions

What are the key thermal design considerations when integrating the ET2015-00 in high-density PCB layouts?
The ET2015-00 in its QFN package has an exposed thermal pad that must be soldered directly to a grounded copper pour on the PCB to ensure effective heat dissipation. In high-density designs, insufficient thermal vias under the pad can lead to localized hotspots, potentially degrading performance or reducing long-term reliability. A minimum of nine 0.3 mm thermal vias connected to an internal ground plane is recommended to maintain junction temperature within safe operating limits under continuous load.
Can the ET2015-00 be used as a drop-in replacement for the Texas Instruments TPS62130 in a 3.3V output configuration?
While both devices are step-down converters with similar output voltage ranges, the ET2015-00 has a different feedback voltage reference (0.6V vs. 0.8V on the TPS62130), requiring recalculation of the feedback resistor network. Additionally, the switching frequency and soft-start timing differ, which may affect stability in existing compensation networks. A redesign of the output filter and feedback loop is necessary to ensure stable operation.
What input voltage transients can the ET2015-00 tolerate during automotive load dump scenarios?
The ET2015-00 is rated for a maximum input voltage of 18V, making it unsuitable for direct connection to automotive 12V systems without additional protection. During load dump events, transients can exceed 40V; therefore, a TVS diode and input filter must be implemented to clamp the voltage below 18V. Without such protection, the device may suffer irreversible damage.
How does the absence of an enable pin on the ET2015-00 affect power sequencing in multi-rail systems?
The ET2015-00 lacks a dedicated enable pin, meaning it begins switching as soon as input voltage exceeds the UVLO threshold. In multi-rail systems requiring precise power-up sequencing, this behavior can cause timing conflicts with downstream regulators. To control startup, an external MOSFET switch on the input rail or a supervisor IC with sequenced outputs must be used to delay power application to the ET2015-00.
Is the ET2015-00 suitable for always-on industrial sensor nodes powered by a 5V rail with intermittent high-current loads?
The ET2015-00 supports input voltages from 3V to 17V and can deliver up to 1.5A, making it viable for such applications. However, its fixed-frequency PWM operation may generate audible noise under light loads if the switching frequency falls within the audio band. For noise-sensitive environments, consider adding a small preload or selecting a device with pulse-skipping or forced PWM mode, though this may require migration to a different part.
What layout practices are critical to avoid instability in the ET2015-00’s feedback network?
The feedback trace from the output divider to the FB pin must be kept short and routed away from switching nodes (SW pin) and inductor fields to prevent noise coupling. A ground guard ring around the feedback resistors and placement of the feedback components close to the IC reduce susceptibility to EMI. Poor layout can introduce ripple or oscillation, especially under dynamic load conditions.
Can the ET2015-00 operate reliably in ambient temperatures above 85°C without derating?
The ET2015-00 has a maximum junction temperature of 125°C. At 85°C ambient, thermal resistance from junction to ambient (θJA) in a typical 4-layer PCB is approximately 40°C/W. With a 1W power dissipation, the junction temperature reaches 125°C, leaving no margin for transient spikes or elevated input voltages. Derating output current or improving airflow is advised for sustained operation above 80°C ambient.
Are there known compatibility issues when replacing the ET2015-00 with the Analog Devices LTC3632 in existing designs?
The LTC3632 has a higher maximum input voltage (15V vs. 17V for ET2015-00) but operates at a lower switching frequency (2.25MHz vs. 2.1MHz), which may require adjusting the inductor value. Additionally, the LTC3632 uses a different compensation scheme and has a lower current limit, potentially requiring a larger inductor or output capacitor to maintain transient response. Full validation under load-step conditions is recommended before migration.
How should the ET2015-00 be configured for low-noise operation in sensitive analog measurement systems?
To minimize output ripple and switching noise, use a low-ESR ceramic output capacitor placed as close as possible to the VOUT and GND pins. A Pi filter (LC or RC) on the output can further attenuate high-frequency noise. Additionally, synchronizing the ET2015-00 to an external clock (if supported) or selecting a fixed-frequency variant helps avoid beat frequencies that could interfere with ADC sampling.
What failure modes should be anticipated if the ET2015-00 is subjected to reverse polarity connection?
The ET2015-00 lacks built-in reverse polarity protection. Applying reverse voltage can cause immediate damage to the internal power MOSFETs and control circuitry due to forward-biased parasitic junctions. To prevent this, a series Schottky diode or a P-channel MOSFET-based protection circuit must be added on the input rail, especially in field-deployable or user-accessible applications.
