Frequently Asked Questions
What input voltage range does the LM22673TJ-5.0/NOPB accept for step-down regulation?
The LM22673TJ-5.0/NOPB accepts input voltages from 4.5 V to 42 V, making it compatible with 12 V automotive systems, 24 V industrial rails, and unregulated adapter supplies that may spike well above their nominal voltage. This wide range allows a single design to serve multiple supply environments without component substitution.
How does the adjustable soft-start feature of the LM22673TJ-5.0/NOPB protect power-up circuits?
The LM22673TJ-5.0/NOPB's soft-start pin allows the designer to set the output voltage ramp rate by selecting an external capacitor value. A slower ramp limits the inrush current drawn from the input supply during start-up, protecting upstream fuses, bulk capacitors, and battery contacts from high-peak current stress, which is especially important in automotive and battery-powered applications.
What output current can the LM22673TJ-5.0/NOPB deliver continuously and at what output voltage?
The LM22673TJ-5.0/NOPB delivers up to 3 A of continuous output current at a fixed 5 V output. This capacity is sufficient to power several microcontrollers, a CAN transceiver, sensor arrays, and small logic circuits simultaneously from a single regulator, reducing the total number of power ICs needed in distributed industrial or automotive electronic systems.
Which temperature range qualifies the LM22673TJ-5.0/NOPB for automotive and industrial deployment?
The LM22673TJ-5.0/NOPB is rated for operation from -40°C to 125°C junction temperature, covering the full automotive temperature grade requirements. This range ensures reliable regulation in under-hood automotive environments, outdoor industrial enclosures, and vehicle telematics modules that experience wide ambient temperature swings over their service life.
