DC2615A

DC2615A demonstration circuit features the LTC®7151S in a high efficiency 1.2V/15A step-down regulator with an input voltage range of 3.1V to 20V and a 1MHz switching frequency. The Silent Switcher®2 technology reduces the switching noise while the internal MOSFETs of the LTC7151S provide high efficiency over a wide input voltage range. No current sense resistor is required. The LTC7151S employs a controlled on-time, valley current mode architecture. This architecture allows for a short minimum on-time which is ideal for high stepdown ratios. In addition, the architecture provides a fast load step response by allowing the switch node pulses to compress after the load steps up. Other features of the DC2615A include selectable light load operating modes of continuous conduction mode (CCM) or discontinuous mode (DCM), SYNC pin to synchronize the regulator to an external clock, PGOOD pin and RUN pin.
