The NCP1079ABP100G is a high performance monolithic switching regulator with low quiescent current and wide input voltage range of 1.8 V to 40 V. It integrates an internal power MOSFET switch, thereby eliminating the need for an external P-channel MOSFET, and allowing a wide range of inputcapacitance.The NCP1079ABP100G is designed to quickly and efficiently step-down up to 100W load from sources such as switchedmode power supplies (SMPS).It is ideal for applications requiring low output voltage ripple and low quiescent current.The NCP1079ABP100Gis a monolithic step-down AC/DC converter with wide input voltage range from 1.8 V to 40 V. It integrates a low-RDS(on) internal 200V power MOSFET switch, and is optimized for high efficiency. The synchronous rectification design allows for higher efficiency than traditional PWM-controlled CCM designs.The switching frequency is adjustable from 50 kHz to 200 kHz to provide optimal efficiency for a given design. The NCP1079ABP100G operates in a fixed frequency, pulse width modulated current mode. The on-chip soft start limits inrush current and the undervoltage lockout prevents the regulator from attempting to regulate during start-up.

The NCP1079ABP100G works by first being powered on and then stepping down the input voltage range to a lower pre-configured output voltage. The input voltage is fed through an inductor/capacitor filter to create a stable output voltage. The NCP1079ABP100G also features a built-in MOSFET switch that works in tandem with the inductor/capacitor filter. The MOSFET switch alternately passes and blocks the input voltage to regulate the output voltage. This process continues until the desired output voltage is reached.The NCP1079ABP100G operates in a quasi-resonant topology, reducing the number of parts required and providing good efficiency over a wide load range. The output ripple is minimized, resulting in a very clean output.

The NCP1079ABP100G is suitable for a wide range of applications, including industrial controls, telecom and datacom systems, USB power supplies, battery chargers, and portable electronics. It is also suitable for use in embedded systems and alternative energy applications. Additionally, the NCP1079ABP100G is ideal for applications where size and weight are a concern, as it is significantly smaller than other switching converter solutions.

In summary, the NCP1079ABP100G is an efficient, high performance monolithic switching regulator with a wide input voltage range of 1.8 V to 40 V and low quiescent current. It integrates a low-RDS(on) internal power MOSFET switch, and operates in a fixed frequency, pulse width modulated current mode. The on-chip soft start limits inrush current and the undervoltage lockout prevents the regulator from attempting to regulate during start-up. The switching frequency is adjustable from 50 kHz to 200 kHz to provide optimal efficiency for a given design. The NCP1079ABP100G is ideal for applications requiring low output voltage ripple and low quiescent current, and is suitable for a wide range of applications including industrial controls, telecom and datacom systems, USB power supplies, battery chargers, and portable electronics.
