We present Suzaku observations of the Galactic black hole candidate SWIFT J1753.5-0127 in the low-hard state .
The broadband coverage of Suzaku enables us to detect the source over the energy range 0.6 – 250 keV .
The broadband spectrum ( 2 – 250 keV ) is found to be consistent with a simple power-law ( \Gamma \sim 1.63 ) .
In agreement with previous observations of this system , a significant excess of soft X-ray flux is detected consistent with the presence of a cool accretion disc .
Estimates of the disc inner radius infer a value consistent with the ISCO ( R _ { in } \lesssim 6 ~ { } R _ { g } , for certain values of , e.g . N _ { H } ,~ { } i ) , although we can not conclusively rule out the presence of an accretion disc truncated at larger radii ( R _ { in } \sim 10 - 50 ~ { } R _ { g } ) .
A weak , relativistically-broadened iron line is also detected , in addition to disc reflection at higher energy .
However , the iron-K line profile favours an inner radius larger than the ISCO ( R _ { in } \sim 10 - 20 ~ { } R _ { g } ) .
The implications of these observations for models of the accretion flow in the low-hard state are discussed .
