NCP3136MNTXG is a DC/DC switching module manufactured by ON Semiconductor. It is an integrated package that combines all the necessary components for efficient power delivery and regulation. It is designed for space-constrained applications where power conversion is needed, such as automotive, industrial, and consumer electronics. This DC/DC switching module is one of the most efficient on the market, boasting higher power density, less heat dissipation, and improved performance compared to traditional step-up or step-down regulator designs.

With its simple one-panel PCB design, the NCP3136MNTXG DC/DC switching module can enable a fully-accessible, regulated power system for complex, space-constrained applications. The module includes a temperature-compensated, high-efficiency power MOSFET switch, an integrated current sense resistor, and a high-accuracy, low-output voltage error amplifier. Furthermore, an onboard PWM comparator with external ramp voltage allows for setting the switching frequency.

The NCP3136MNTXG DC/DC switching module can regulate input voltages ranging from 5 V to 24 V and 0.5 V to 6.5 V output configurations. It offers a wide range of current capability ranging from 0.75 A to 5 A. The light-load switching frequency can be set via external resistors, ensuring optimized system efficiency across load conditions and regulating the output voltage accurately even at very light load conditions.

The NCP3136MNTXG DC/DC switching module offers a variety of protection features for safe and reliable operation. It is equipped with an integrated over-temperature, over-current, and over-voltage protection circuit to protect the system from being damaged due to an unexpected condition. Furthermore, an adjustable blanking time ensures enhanced precision and excellent load transient response.

The NCP3136MNTXG DC/DC switching module is ideal for automotive, industrial, and consumer applications, where space is limited and high efficiency is needed. It is particularly suitable for battery-operated systems, adapters, and wireless communication applications. This module can also be used in portable electronic devices with low-power designs and multiple power rails.

The working principle of the NCP3136MNTXG DC/DC switching module is based on a pulse-width modulation (PWM) control topology. The module monitors the output voltage with the aid of an onboard comparator, and then adjusts the duty cycle of the generated PWM signals to regulate the output voltage. The PWM signals are fed to the gate of the power MOSFET switch, which in turn regulates the current flow through the output inductor, thus regulating the output voltage. As the load changes, the duty cycle of the generated PWM signals is also adjusted, ensuring a stable output voltage with low output voltage ripple.
