The NCV7381GEVK is a 32-bit low-cost, low-power buck converter evaluation and demonstration board which is developed by ON Semiconductor. It features a high-efficiency step-down DC/DC buck converter optimized for battery-powered, LCD backlight and white LED applications. Cost-sensitive implementations are possible due to the low ownership cost of the entire NCV7381GEVK kit.

The NCV7381GEVK is implemented around a proven, highly-integrated regulator IC predominantly consisting of an HV Sense FET, system power ramps, and associated logic for control the device. The device operates from 4Vin to 16Vin input voltage range, and its output current is adjustable from 0.5A to 4A. With an operating efficiency up to 95%, the NCV7381GEVK is optimized for applications with up to 65V input voltages and up to 6A output current. In addition, the kit integrates a wide range of features that enable users to adjust their output voltage, select its operating frequency and switch its operating mode.

In terms of application field and working principle, the NCV7381GEVK is designed primarily for buck converter solutions in consumer, industrial, automotive and power tool applications. It works in 8-bit energy-efficient Constant On-Time (COT) control mode and is capable of achieving fast transient responses and high efficiency in light or heavy loading conditions. The control loop of the NCV7381GEVK includes an on-chip trimming technique to optimize the line and load transient response according to the gas gauge measurements in the battery packs. The torque modulation technique used is non-overlapping dual-pulse-width modulation (PWM), which produces two drive pulses with the same duty cycle but of different pulse widths.

The NCV7381GEVK comes with linear input voltage control mechanism allowing current-mode control and automatic voltage-high-low sensing. It also features a current limit, an adjustable peak current limit and a low-side driver shutdown. These features enable the device to maintain a stable voltage supply in the output regardless of changes in the input voltage. Additionally, NCV7381GEVK also provides output voltage tracking capability. This enables the device to track the input voltage and match the output voltage accordingly.

The NCV7381GEVK evaluation kit provides a comprehensive environment that enables users to explore the device features, optimize design parameters, and design-in the device into different applications. With the kit, users can generate a custom graphical user interface (GUI) to execute core features seamlessly and with real-time graphical control. The kit also supports margin and endurance bracket testing for total design cycle confidence.

In conclusion, the NCV7381GEVK is a perfect choice for customers looking for a high efficiency, low-cost evaluation and demonstration board for buck regulator solutions. Its ease of use, excellent performance, and cost-effective characteristics make NCV7381GEVK an ideal choice for battery-powered, LCD backlight, and white LED applications.
