MC34716EP

The NXP Semiconductors MC34716EP is a highly integrated, dual synchronous buck switching regulator designed for Double-Data-Rate (DDR) memory power supplies. It features integrated N-channel power MOSFETs for space efficiency and cost-effectiveness.

This device operates with an input voltage range of 3.0 V to 6.0 V and provides output voltages from 0.6 V to 3.6 V with ±1% accuracy. Channel one offers a 5.0 A source-only drive capability, suitable for VDDQ supply. Channel two can sink and source up to 3.0 A, ideal for tracking an external reference voltage for termination voltage (VTT) in DDR memory buses (DDR, DDR2, DDR3, Low power DDR3/DDR4).

The MC34716EP supports a programmable switching frequency from 200 kHz to 1.0 MHz. It includes essential protection features such as over-current limit, short-circuit protection, thermal shutdown, and output over-voltage/under-voltage detection. The regulator also provides an active low power good output signal and active low standby/shutdown inputs.

Housed in a 26-pin QFN (5x5) package with an exposed pad, the MC34716EP is designed for surface mounting. Its thermally enhanced package and integrated components simplify complex designs, making it a high-performance point-of-load power supply solution.
