Frequently Asked Questions
What input voltage range does the LM25017SD/NOPB support?
The LM25017SD/NOPB supports an input voltage range of 7.5V to 48V, making it suitable for industrial 24V and 48V bus systems, telecom power rails, and wide-range unregulated DC inputs from batteries or rectified AC supplies. The wide range eliminates the need for pre-regulation in most industrial power conversion scenarios.
What control mode does the LM25017SD/NOPB use?
The LM25017SD/NOPB uses voltage-mode PWM (Pulse Width Modulation) control, which provides a fixed switching frequency and straightforward external compensation network design. Voltage-mode control simplifies the feedback loop design compared to current-mode control and provides inherent noise immunity in electromagnetically noisy industrial environments.
Does the LM25017SD/NOPB require an external MOSFET?
Yes, the LM25017SD/NOPB is a controller IC that requires an external N-channel MOSFET as the power switch in the buck converter. This architecture allows designers to select the MOSFET for their specific voltage, current, and efficiency requirements, enabling the LM25017 to scale across a wide range of output current and power level specifications.
Is the LM25017SD/NOPB RoHS compliant?
Yes, the LM25017SD/NOPB is RoHS compliant as indicated by the NOPB (no lead, no bromine) suffix and JESD-609 e3 code. The 8-pin no-lead package uses lead-free solder terminations meeting EU RoHS Directive requirements, qualifying the device for use in environmentally certified industrial and telecommunications equipment.
