What are the key features of LT8630IFE#PBF?
- Wide 3V to 100V input voltage range supporting automotive, industrial, and high-voltage power supply applications without additional protection circuitry
- Adjustable output voltage from 0.8V to 60V via current-mode PWM control for precise regulation across a broad output range
- Current-mode control architecture providing inherent cycle-by-cycle current limiting and fast transient response for demanding load conditions
- TSSOP-20 package enabling compact high-voltage DC-DC converter layouts with minimal external components
What is LT8630IFE#PBF used for?
The LT8630IFE#PBF is designed for high-voltage step-down (buck) power conversion in industrial automation, telecommunications infrastructure, and automotive systems where input rails can reach 100V. Its adjustable 0.8V to 60V output range makes it versatile for generating multiple regulated rails from a single high-voltage bus. The current-mode PWM architecture ensures stable regulation with fast transient response, making it well-suited for powering processors, FPGAs, and mixed-signal loads in harsh environments.

Frequently Asked Questions
What is the input voltage range of LT8630IFE#PBF and which industrial bus voltages does it support directly?
The LT8630IFE#PBF accepts input voltages from 3V to 100V, directly supporting 12V, 24V, 48V, and 72V industrial bus standards without additional series protection. This wide range makes it suitable for motor drives, PLC power supplies, and off-line industrial converters that must handle transients up to 100V.
How is the output voltage of LT8630IFE#PBF set, and what is the minimum achievable output?
Output voltage is adjusted via an external resistor divider connected to the feedback pin, allowing the output to be set anywhere from 0.8V to 60V. The 0.8V minimum output reference enables direct regulation of low-voltage logic rails such as 1.0V or 1.2V digital core supplies from a high-voltage input without intermediate converter stages.
What control architecture does LT8630IFE#PBF use and how does current-mode PWM benefit transient response?
The LT8630IFE#PBF uses current-mode pulse width modulation (PWM) control, which senses inductor current on a cycle-by-cycle basis. This provides automatic cycle-by-cycle current limiting, improves line transient rejection, and simplifies loop compensation compared to voltage-mode control, resulting in faster load step response—critical for powering processors with rapidly changing current demands.
For a 48V industrial rack power supply that must deliver a regulated 5V rail, is LT8630IFE#PBF a suitable single-stage solution?
Yes. With a 48V input well within the 3V to 100V range, and a 5V target output within the 0.8V to 60V adjustable range, the LT8630IFE#PBF can perform this single-stage step-down conversion. Set the resistor divider for 5V output, select an appropriate inductor and capacitor for the switching frequency, and the TSSOP-20 device handles the full conversion in a compact PCB footprint.
