What are the key features of LTC3829IFE#PBF?
- 3-phase synchronous buck topology reduces output ripple by 3x versus single-phase
- 4.5 V to 38 V input range covering telecom 12 V and 24 V bus voltages
- Current-mode PWM control for fast transient response
- Integrated differential remote-sense amplifier for accurate output regulation
- Programmable frequency 50 kHz to 900 kHz per phase
- Overvoltage, overcurrent, and thermal protection with soft-start
What is LTC3829IFE#PBF used for?
The LTC3829IFE#PBF drives high-current point-of-load regulators in server, telecom, and FPGA power supply designs where a 4.5 V to 38 V input must be stepped down to sub-1 V core voltages at tens of amperes. Three interleaved phases reduce input and output capacitor size and ripple by a factor of three compared to a single-phase design. The on-chip differential amplifier corrects for PCB trace voltage drops to maintain precise load-point regulation in high-current applications.

Frequently Asked Questions
What input voltage range does the LTC3829IFE#PBF support, and which bus standards does it cover?
The controller accepts 4.5 V to 38 V at the input, covering standard 5 V, 12 V, and 24 V bus voltages used in server, telecom, and industrial power distribution systems without an additional pre-regulator stage.
How does 3-phase interleaving in the LTC3829 reduce the required output capacitance?
With 3 phases switching 120 degrees apart, the effective ripple frequency seen by the output capacitors is 3x the per-phase switching frequency; this reduces peak-to-peak ripple current by up to 3x, allowing a smaller capacitor bank for the same output voltage ripple specification.
When would the LTC3829 be preferred over a simpler single-phase controller for an FPGA core supply?
FPGA core currents can exceed 60 A with fast di/dt transients; the LTC3829 distributes current across 3 phases to keep per-phase inductor size below 1 µH while the differential remote sense corrects millivolt-level IR drops, ensuring the core rail stays within ±1% of the target voltage even under full-load steps.
