Semtech has announced the SC414 and SC424, two small 6 A, 28 V point-of-load voltage regulators, capable of efficiencies up to 96%. The devices have a wide input voltage range of 3 V to 28 V and the fixed 5 V LDO can be used to provide the power for the gate drive bias, allowing the part to operate from a single rail. For optimum efficiency, the internal crossover circuitry bypasses the LDO after startup, if the LDO and buck outputs are the same. Pseudo fixed frequency adaptive on-time control gives the part excellent transient response and reduces the output filter capacitance required. Selectable ultrasonic power save for the SC414 allows the device to operate in discontinuous conduction mode at light load conditions, saving quiescent current, while limiting the ‘floor’ frequency to avoid audible noise. The SC424 has regular power save with no floor frequency, for maximum light-load efficiency.
