NCP1579DR2G Description

Short technical summary and product information.

The ON Semiconductor NCP1579DR2G is a low-cost synchronous buck controller designed for efficient power supply solutions. It operates from an input voltage range of 4.5 V to 13.2 V and can produce output voltages as low as 0.8 V. This 8-pin SOIC device integrates key functions to reduce board space and cost.

 

Key electrical features include a 275 kHz internal oscillator, internal 1 A gate drivers, and a maximum duty cycle of 80%. The controller utilizes voltage mode PWM control and offers adjustable output voltage. Protection features include undervoltage lockout (UVLO) and programmable current limit.

 

The NCP1579DR2G is suitable for applications such as STB, Blue-Ray DVD, LCD TV, and DSP/FPGA power supplies. It comes in a compact 8-SOIC package suitable for surface mount applications.

 

This device is Pb-Free, Halogen Free/BFR Free, and RoHS Compliant.
