产品详情

Demo Circuit 1461 is a high efficiency, high frequency step-down converter, incorporating the LTC3616 monolithic synchronous regulator. The DC1461A has an input voltage range of 2.25V to 5.5V, and is capable of delivering up to 6A of output current. The output voltage of the DC1461A can be set as low as 0.6V, the reference voltage of the LTC3616. The operating frequency range of the DC1461A is either set to a fixed 2.25 MHz by connecting the frequency pin to SVin, set by an external resistor, or synchronized to an external clock, with a range up to 4 MHz. At low load currents, the DC1461A can operate in either noise sensitive applications, due to the capability of the LTC3616 to operate in pulse-skipping mode, or in high efficiency applications, because the LTC3616 also has Burst-Mode capability. The Burst Mode clamp can be set externally.
