NCP3120 Dual 2.0 A, Step-Down DC/DC Switching Regulator The NCP3120 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 NCP3120 provides dual 2.0 A switching regulators with an adjustable 200 kHz − 750 kHz switching frequency. The switching frequency is set by an external resistor. The NCP3120 also incorporates an auto−tracking and sequencing feature. Protection features include cycle−by−cycle current limit and undervoltage lockout (UVLO). The NCP3120 comes in a 32−pin QFN package. Features • Input Voltage Range from 4.5 V to 13.2 V • 12 Vin to 5.0 Vout = 87% Efficiency Min @ 2.0 A • 200−750 kHz Operation • Stable with Low ESR Ceramic Output Capacitor • 0.8 ±1.
