Applications
LTC6908CS6-2#TRPBF is used in switching power supply controllers and DC-DC converter designs to reduce EMI and simplify FCC/CE compliance by spreading clock harmonics over a wider bandwidth. Its 2-phase output also synchronizes multiple converter stages in point-of-load power architectures, reducing input capacitor ripple current by up to 50%.

Frequently Asked Questions
What is the frequency range of LTC6908CS6-2#TRPBF and how is it set?
The LTC6908CS6-2#TRPBF covers 10 kHz to 10 MHz, with frequency programmed by a single external resistor connected to the SET pin, allowing designers to target specific switching frequencies for DC-DC converters without external crystal or oscillator circuits.
How does the spread-spectrum feature of LTC6908CS6-2#TRPBF help with EMI compliance?
The built-in SSFM spreads the fundamental and harmonic energy of the 10 kHz–10 MHz clock over a wider frequency band, reducing peak emissions measured in a 120 kHz bandwidth by typically 10–15 dB, which simplifies passing CISPR 32 and FCC Part 15 radiated emission limits.
What are the advantages of using LTC6908CS6-2#TRPBF over a single-output clock oscillator in a 2-phase converter?
The 2-phase outputs of LTC6908CS6-2#TRPBF are inherently 180° phase-shifted, so two converter phases driven from this single 6-pin SOT-23 IC cancel each other's input ripple current, reducing bulk capacitance requirements by up to 50% and lowering overall BOM cost compared to two independent oscillators.
