What are the key features of LTC6908IDCB-1#TRMPBF?
- 10 kHz to 10 MHz programmable frequency range with 2-phase outputs enables precise timing coordination in dual-phase DC-DC converters without external phase-shift circuitry
- Built-in spread-spectrum frequency modulation (SSFM) reduces conducted and radiated EMI, simplifying FCC/CE compliance for switching power supplies and portable devices
- 9 ns maximum fall time and surface-mount SOT-23 package deliver clean clock edges with minimal PCB area in noise-sensitive mixed-signal and power management designs
What is LTC6908IDCB-1#TRMPBF used for?
The LTC6908IDCB-1#TRMPBF is used as the timing source for 2-phase interleaved DC-DC boost or buck converters, where its 2 outputs clocked 180 degrees apart reduce input and output ripple current. EMI-sensitive consumer electronics and medical devices rely on its spread-spectrum modulation to lower peak spectral emissions, easing pre-compliance testing at 10 kHz to 10 MHz operating frequencies. Wireless communication base station power supplies and portable instrument clock generators also benefit from its adjustable frequency and low-EMI profile.

Frequently Asked Questions
How does the spread-spectrum modulation of the LTC6908IDCB-1#TRMPBF reduce EMI in a switching power supply?
The LTC6908IDCB-1#TRMPBF uses spread-spectrum frequency modulation to vary its clock frequency continuously across a 40% modulation range around the programmed center frequency between 10 kHz and 10 MHz. This spreads the fundamental switching harmonic energy over a wider bandwidth, reducing the peak spectral density measured by a quasi-peak EMI detector and helping designs pass CISPR 22 or FCC Part 15B limits with less filtering.
For a 2-phase interleaved boost converter design, how does the LTC6908IDCB-1#TRMPBF simplify the clocking architecture?
The LTC6908IDCB-1#TRMPBF generates 2 clock outputs that are inherently 180 degrees out of phase, eliminating the need for an external RC phase-shift network or a microcontroller GPIO to stagger the two switching channels. This reduces component count by at least 2 parts and ensures precise phase alignment over the full 10 kHz to 10 MHz frequency range, improving ripple cancellation in the interleaved converter's input capacitor.
What package does the LTC6908IDCB-1#TRMPBF come in, and is tape-and-reel delivery supported for automated PCB assembly?
The LTC6908IDCB-1#TRMPBF is housed in a small surface-mount package (SOT-23 style DCB footprint) and is supplied on tape and reel, as indicated by the TRMPBF suffix. This packaging is fully compatible with standard pick-and-place assembly at production volumes, and the PBF designation confirms RoHS-compliant, lead-free solder compatibility for global market shipment.
