NCP3122
Dual 2.0 A, Step-Down DC/DC Switching Regulator
The NCP3122 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 NCP3122 provides dual 2.0 A switching regulators with an adjustable 200 kHz − 2200 kHz switching frequency. The switching frequency is set by an external resistor. The NCP3122 also incorporates an auto−tracking and sequencing feature. Protection features include cycle−by−cycle current limit and undervoltage lockout (UVLO). The NCP3122 comes in a 32−pin QFN package.
