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
G
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.
Features
? Input Voltage Range from 4.5 V to 13.2 V
? 12 V in to 5.0 V out = 85% Efficiency Min @ 3.0 A
? 200 ? 750 kHz Operation
? Stable with Low ESR Ceramic Output Capacitor
? 0.8 ± 1.5% FB Reference Voltage
? External Soft ? Start
? Out of Phase Operation of OUT1 & OUT2
? Auto ? Tracking and Sequencing
? Enable/Disable Capability
? Hiccup Overload Protection
? Low Shutdown Power (I q < 100 m A)
