What are the key features of LT3980EDE#TRPBF?

58 V maximum input voltage handling automotive, industrial, and telecom 48 V bus inputs directly
75 µA quiescent current for efficient always-on power regulation in standby-sensitive systems
2.4 MHz switching frequency enabling small external inductors and capacitors for compact PCB designs
Current-mode PWM control for fast transient response and cycle-by-cycle overcurrent protection

What is LT3980EDE#TRPBF used for?

The LT3980EDE#TRPBF serves as a primary DC-DC converter in automotive electronics, industrial 24 V and 48 V bus systems, and telecom power supplies where wide input voltage range is essential. Its 75 µA quiescent current and 2.4 MHz switching frequency make it suitable for always-on voltage rails in vehicle control modules and smart building sensors. Engineers also deploy it in battery-backed systems, point-of-load regulators, and test equipment requiring efficient 2 A buck conversion from high-voltage inputs.

Frequently Asked Questions

How does LT3980EDE#TRPBF's 58 V input rating benefit automotive 48 V mild hybrid system designs?

The LT3980EDE#TRPBF tolerates input voltages up to 58 V, comfortably covering the 48 V nominal bus plus load dump transients reaching 52 V in mild hybrid vehicles. This eliminates the need for external input clamping, simplifying the power supply design and reducing BOM cost in automotive body electronics.

For a solar panel IoT gateway that must remain active 24/7, how does the 75 µA quiescent current affect power budget?

At 75 µA quiescent current from a 12 V source, the LT3980EDE#TRPBF consumes only 0.9 mW in light-load operation, extending battery backup runtime by hours compared to regulators drawing 500 µA or more. This makes it practical for solar-powered gateways where standby power is tightly budgeted across -40°C to +125°C.

What inductor and capacitor sizes does the 2.4 MHz switching frequency enable for the LT3980EDE#TRPBF?

At 2.4 MHz switching frequency, the LT3980EDE#TRPBF typically requires inductors in the 1 µH to 4.7 µH range and output capacitors as small as 10 µF to 22 µF, compared to 22 µH to 100 µH inductors needed at 300 kHz. This reduces total converter solution size by more than 50% on constrained PCB areas.

Is LT3980EDE#TRPBF suitable for stepping down a 24 V industrial rail to 5 V at 1.5 A continuously?

Yes, the LT3980EDE#TRPBF handles 3 V to 58 V input and delivers up to 2 A output, so a 24 V to 5 V conversion at 1.5 A is well within its ratings. At that operating point, efficiency typically exceeds 85%, and the current-mode control ensures stable regulation across load steps from 0 A to 2 A.
