LTM4628IY#PBF FAQs
1.Q: What related parts does Analog Devices offer for similar applications?
A: Related parts include Analog’s LTM46xx series (multi-output μModule regulators) and ADP50xx (high-efficiency step-down converters) for comparable power needs.
2.Q: How does load regulation performance look for this converter?
A: Load regulation is ±0.3% (typical) across 0–8A loads, ensuring stable output voltage under dynamic current conditions.
3.Q: What certifications or standards comply with this DC/DC converter?
A: The module is EAR99 (export-controlled) and follows industrial-grade standards but lacks explicit automotive (AEC-Q) or PPAP certifications. Confirm compliance per application requirements.
4.Q: What is the thermal resistance (θJA) of the BGA package?
A: Thermal resistance is typically ~15°C/W (junction-to-ambient) with proper PCB thermal vias and copper area. Ensure adequate heat sinking for high-load conditions.
5.Q: What are the absolute maximum ratings for this Analog Devices converter?
A: Absolute max ratings: Input voltage ≤ 28V, output current ≤ 8A per channel, operating temperature ≤ 125°C. Exceeding these may cause permanent damage.
6.Q: What is the pinout configuration of this 144-lead BGA package?
A: The 144-ball BGA (15mm × 15mm) includes dedicated pins for input voltage, dual outputs, feedback control, enable/disable logic, and ground/power pads. Refer to the datasheet for the detailed pinout diagram.
7.Q: What are the typical applications for this dual-output DC/DC converter?
A: Typical applications include industrial automation, telecom infrastructure, FPGA/ASIC power supplies, and distributed power systems requiring compact, high-current PoL solutions.
8.Q: What are the key features of the Analog Devices non-isolated PoL module (2-output DC/DC converter)?
A: Key features include dual adjustable outputs (0.6V–5.5V, 8A each), wide input range (4.5V–26.5V), 780kHz switching frequency, high efficiency (step-down topology), and industrial temperature range (-40°C to +125°C).
