NCS1002DR2G Description

Short technical summary and product information.

The NCS1002DR2G is a highly integrated secondary-side controller from On Semiconductor, designed for Switching Mode Power Supply (SMPS) applications requiring dual control loops for Constant Voltage (CV) and Constant Current (CC) regulation. It integrates a 2.5 V voltage reference and two precision operational amplifiers.

 

Key features include a wide power supply range of 3 V to 32 V and an operating temperature range of -40°C to 105°C. The device offers low input offset voltage (0.5 mV typical) and high ESD protection (2 kV). It is supplied in a compact 8-pin SOIC package, making it suitable for space-constrained applications such as battery chargers.

 

External components like a resistor divider and a sense resistor are needed to complete the control loops. The resistor divider sets the voltage regulation set point, while the sense resistor determines the current regulation set point. The NCS1002DR2G is ideal for battery chargers and other switch-mode power supplies.

 

This controller is available in an 8-SOIC surface mount package. It is designed to be Pb-Free.
