The NCP1337PG is a fixed-frequency off-line current-mode PWM controller designed to work with external MOSFETs in order to supply power to most kinds of AC/DC-isolated and non-isolated power supplies. It is capable of generating output power with an efficiency as high as 90%. The NCP1337PG’s high-density and low-cost USB/Power Delivery applications, adaptable to a wide range of supply voltages and light load conditions, make it an ideal choice for AC/DC converters, offline switchers, and personal computer power supplies.

The NCP1337PG is an ideal solution for AC/DC converters and offline switchers that have compact size, high power density and high efficiency. The NCP1337PG is an integrated full-bridge controller that uses current mode control. It works by sensing the amplitude and slope of the current through sensing resistors, and then adjusts the current to keep the slope and amplitude at the pre-set levels. This leads to fast load responses, which are beneficial for applications that require fast changes in load currents.

The NCP1337PG uses the peak current mode control technique, which reduces the total harmonic distortion (THD) of the output waveform. The NCP1337PG also features input overvoltage protection, output short-circuit protection, and an under-voltage lockout (UVLO) that prevents the output voltage from falling to unsafe levels. Additionally, the NCP1337PG includes a wide-range of soft start and slotted delay circuit, allowing it to be used in many different applications.

In terms of efficiency, the NCP1337PG offers an excellent efficiency of up to 90%. It is also capable of switching up to 10MHz, with a quiescent current of only 6mA. Additionally, the NCP1337PG will operate well at low input voltages, providing high efficiency with low-cost switchers.

The NCP1337PG is also suitable for light load conditions as it provides intermediate current regulation for better performance under light loads. The NCP1337PG also offers a shutdown feature that enables the device to power down when the input voltage falls below a pre-set threshold. This helps reduce the power waste associated with light load conditions, making the NCP1337PG an ideal choice for applications such as adapters and chargers.

The NCP1337PG is a great choice for AC/DC converters and offline switchers due to its high power density, high efficiency and light load conditions. Furthermore, the integrated features of the NCP1337PG such as overvoltage protection, shut down and peak current mode control, make it an excellent choice for any application. With its long term and reliable operation, the NCP1337PG is the perfect choice for any AC/DC converters and offline switchers.
