The NCP3121 is a dual buck converter designed for low voltage applications requiring high efficiency. This device is capable of producing an output voltage as low as 0.8 V. The NCP3121 provides dual 3.0 A switching regulators with an adjustable 200 kHz - 750 kHz switching frequency. The switching frequency is set by an external resistor. The NCP3121 also incorporates an auto-tracking and sequencing feature. Protection features include cycle-by-cycle current limit and undervoltage lockout (UVLO). The NCP3121 comes in a 32-pin QFN package.
