NCP3121
Dual 3.
0 A, Step-Down DC/DC Switching
Regulator
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.
