NTD5862N-1G is a highly integrated Power Management IC, specifically designed for DC/DC conversion of battery powered applications. It employs the latest in Power-Up/Down technology and can be used in a variety of applications. The NTD5862N is suitable for low-voltage and low-power applications such as mobile phones, PDAs, and portable data systems.

The NTD5862N features a high-performance power and logic control. The design includes two separate power channels for fast and efficient supply control. The first power channel, referred to as the MOD power channel, is the main switching channel for the device. It includes latched and regulated synchronous MOSFETs with adjustable speed, voltage and current range. The second power channel, referred to as the VOUT power channel, is used to supply the output voltage. This channel can be used to adjust the output voltage or provide current limiting capability.

The NTD5862N also includes an integrated Solar Control Input (SCI) which allows external control of DC/DC converter input voltage. This allows the device to quickly and easily tune the output voltage of the converter accurately across a wide input voltage range. The SCI input also allows the device to detect when the battery voltage is low and circuits for immediate response in order to safely transition off of battery power. This helps to ensure that the connected circuits do not power up and consume all of the battery capacity.

The NTD5862N is typically implemented in either a push-pull or synchronous Buck circuit. The push-pull circuit provides a compact solution with low losses and a small phase delay. The synchronous Buck circuit offers an increased flexibility while providing enhanced efficiency due to improved electrical characteristics as well as an adjustable output current.

The NTD5862N is designed using advanced process technology and optimized for low operating and standby power. It utilizes an on-chip power controller and protection logic and integrates high performance, low-cost synchronous MOSFETs for high efficiency DC/DC conversion. The device also includes low-impedance current sensing which helps to ensure accurate current measurement and power supply control. The NTD5862N is also optimized for low noise, low EMI, and light load efficiency.

The NTD5862N-1G provides a complete solution for DC/DC conversion with full protection features, low operating power and optimized efficiency. This feature-rich device offers unprecedented flexibility and is suitable for a range of applications from portable equipment to automotive and industrial applications.
