NCP3066MNTXG Description

Short technical summary and product information.

The NCP3066MNTXG from ON Semiconductor is a monolithic switching regulator specifically designed to deliver constant current for powering high-brightness LEDs. This device operates with a low feedback voltage of 235 mV, enabling precise regulation of the LED string's average current.

 

With a wide input voltage range from 3.0 V to 40 V, the NCP3066MNTXG is suitable for various lighting applications, including those powered by 12 Vac, 12-36 Vdc supplies, or unregulated sources like rechargeable batteries. It can be configured in Step-Down (Buck), Step-Up (Boost), and Voltage-Inverting topologies with minimal external components.

 

The regulator includes an ON/OFF pin for PWM dimming capability or low-power shutdown. Key features include an integrated 1.5 A switch, cycle-by-cycle current limit, and no control loop compensation requirement. The operating frequency is adjustable up to 250 kHz.

 

Packaged in an 8-DFN (4x4) with an exposed pad, the NCP3066MNTXG is designed for surface mounting. It operates within a temperature range of 0°C to 85°C (TA). This device is suitable for applications such as automotive and marine lighting, constant current sources, high-brightness LED drivers, and low voltage landscape lighting.
