The PM6670S from Quarktwin Technology Ltd. is a complete power supply regulator specifically designed for DDR2 and DDR3 memory applications, adhering to JEDEC specifications. It features a constant on-time (COT) buck controller, a 2 Apk sink/source low dropout (LDO) regulator, and a 15 mA low noise buffered reference. The device supports an input voltage range of 4.5 V to 28 V and provides adjustable output voltages from 0.9 V to 2.6 V, with fixed outputs of 1.8 V for DDR2 and 1.5 V for DDR3. The PM6670S is equipped with fast load transient response capabilities, making it suitable for both electrolytic and ceramic output capacitors. It includes protections such as negative current limit, latched over-voltage protection (OVP), and under-voltage protection (UVP). The device also offers high impedance output in sleep states S3 and S4/S5, ensuring efficient power management during low-power modes. Applications include notebook computers, handheld devices, and CPU and chipset I/O supplies.
