NCS1002ADR2G Description

Short technical summary and product information.

The NCS1002ADR2G from ON Semiconductor is a highly integrated secondary-side controller IC designed to reduce power consumption in applications requiring efficient Constant Voltage (CV) and Constant Current (CC) regulation. This device is an upgrade from the NCS1002, focusing on enhanced efficiency.

 

Key features include a wide power supply range of 3 V to 36 V, a low input offset voltage of 0.5 mV typical, and low quiescent current of 75 µA per op amp at 5 V. It also offers high ESD protection up to 2 kV.

 

The NCS1002ADR2G integrates a 2.5 V voltage reference and two precision op amps. One op amp is dedicated to the voltage control loop, while the second is an independent amplifier for current control. External components like resistor dividers and sense resistors are needed to complete the control loops.

 

Packaged in a compact 8-pin SOIC, the NCS1002ADR2G is suitable for space-constrained applications such as battery chargers and switch mode power supplies. Its operating temperature range is -40°C to 105°C.
