SC2544: High Performance Wide Input Range Dual Synchronous Buck Controller | Semtech

The SC2544 is a high performance dual PWM Controller It is designed to convert a wide ranged input voltage down to two independent output rails. The PWM operations of the two channels are 180 degree out of phase which CAN greatly reduce the size and the cost of the input capacitors. Synchronous Buck PWM topology and volt- age mode control allow high efficiency operation, fast transient responses, and flexible component selection for easy designs. A 10V internal linear Regulator pro- vides the bias for the controller, and this voltage is opti- mized for Gate drivers to deliver high efficiency. The power sequencing is fully supported including independent start up, and power good output. In the shut down mode the controller only draws 100nA from the supply. The con- troller also offers full protection features for the condi- tions of under voltage, over voltage, and the over current. There is no need for a current sensing resistor because the MOSFET on resistance is used for the sensing element. The switching frequency is adjustable from 100 kHz to 300 kHz. Two packages TSSOP-24 and MLPQ-24 are offered. By Semtech Corporation
