Linear introduces USB 5 V, 2.5 A, 42 V input synchronous buck with cable drop compensation

September 24, 2013

Linear Technology Corp. announces the LT8697, a 2.5 A, 42 V input capable synchronous step-down switching regulator designed to power 5 V USB applications. The LT8697 delivers precise 5 V regulation at a remote USB port using programmable cable drop compensation to accurately correct the voltage drop from a long connecting cable regardless of variations in load current. The LT8697’s forced continuous operation enables the LT8697 to sink current, maintaining full frequency operation at zero load, further enhancing accurate 5V regulation during load transients.
