What are the key features of LTC7801IFE#TRPBF?
- Wide 4 V to 140 V input range supporting high-voltage industrial and automotive rails
- Ultra-low quiescent current minimizing standby power in always-on systems
- Current-mode PWM control for inherent cycle-by-cycle current limiting and fast transient response
- Synchronous rectification support improving efficiency across light and heavy load conditions
- 24-lead SSOP package with exposed pad for enhanced thermal dissipation
What is LTC7801IFE#TRPBF used for?
The LTC7801IFE#TRPBF is used in industrial automation power supplies, telecom rectifiers, and 48 V bus converters that must step down from high input voltages up to 140 V to regulated lower rails efficiently. It suits automotive on-board charger auxiliary supplies and solar panel power management where wide input transients are common. Its low quiescent current and current-mode control also make it attractive for always-on battery backup systems requiring high efficiency at both light and full load.

Frequently Asked Questions
What is the maximum input voltage the LTC7801IFE#TRPBF can handle, and what industrial rail voltages does that support?
The LTC7801IFE#TRPBF accepts input voltages from 4 V to 140 V, making it suitable for 48 V telecom bus rails, 72 V industrial systems, and 100 V automotive transient environments where most standard controllers would require input protection or pre-regulation stages.
How does the current-mode PWM control in the LTC7801IFE#TRPBF improve converter reliability?
Current-mode PWM control provides cycle-by-cycle peak current limiting, protecting the external switching MOSFET and inductor during overload and short-circuit events; combined with a typical switching frequency programmable up to several hundred kHz, the LTC7801IFE#TRPBF enables fast transient response and stable regulation across wide load swings.
In which package does the LTC7801IFE#TRPBF ship, and how does this benefit high-density board designs?
The LTC7801IFE#TRPBF is housed in a 24-lead SSOP package with an exposed thermal pad, offering a compact footprint while allowing efficient heat dissipation to the PCB; this enables high-density industrial power boards to integrate a full 140 V synchronous buck controller without allocating excessive board area.
When is LTC7801IFE#TRPBF a better choice than a fixed-frequency controller for a 48 V to 5 V conversion?
For a 48 V to 5 V conversion with a 10:1 step-down ratio, the LTC7801IFE#TRPBF's current-mode architecture gives it superior line-transient rejection and simpler loop compensation compared to voltage-mode fixed-frequency controllers; at light loads below 100 mA the low quiescent current keeps standby power under 1 mW, which fixed-frequency alternatives cannot match.
