NXP Semiconductors Special Purpose Regulators MC34712EP

The MC34712EP from Quarktwin Technology Ltd. is a fully integrated synchronous buck switching regulator designed for point-of-load applications, particularly suitable for DDR memory buses including DDR, DDR2, DDR3, and DDR4. It features a 3.0 A sink and source capability, with an input voltage range of 3.0 V to 6.0 V and an output voltage range from 0.6 V to 1.35 V, maintaining an accuracy of ±1%. The device supports programmable switching frequencies from 200 kHz to 1.0 MHz, with a default frequency of 1.0 MHz. The MC34712EP includes several protection features such as overcurrent limit, short-circuit protection, thermal shutdown, and output overvoltage/undervoltage detection. It also provides a buffered reference output voltage for memory chipsets and has active low power-good output signals along with standby and shutdown inputs. The product is housed in a thermally enhanced 24-pin exposed pad QFN package, making it a compact solution for complex designs requiring efficient power management.
