LM2671N-12/NOPB

The LM2671N-12/NOPB is a DC-DC switching regulator specially designed to provide a wide input voltage range with a high voltage supply and negligible standby power. It is a fully integrated, single-chip solution that has the best-in-class output current capability and compact size. The LM2671N-12/NOPB is ideal for a variety of applications such as battery management and portable computing systems.

Working Principle:
The LM2671N-12/NOPB has an internal power switch which operates in pulse width modulation (PWM) mode. The power switch is enabled/disabled under the control of an internal control loop that operates in fixed off-time mode. The off-time is designed to be of a fixed duration and set with an internal resistor network. The internal control loop clocks at a fixed rate of 250kHz and determines an optimised fixed off-time and duty cycle which is used to set the current limit and regulate the output voltage. The current limit and output voltage are the primary parameters controlling the operation of the regulator.

Application Fields
The LM2671N-12/NOPB DC-DC switching regulators are versatile and can be used for a variety of different applications. These include battery management, portable computing systems and a host of other applications that require a voltage regulator with negligible standby power consumption. The LM2671N-12/NOPB is also suitable for automotive and industrial applications such as mobile transceivers and sensors, portable communications and computing applications, microcontrollers, and other applications that require a wide input voltage range with a high voltage supply.The temperature-compensated current limit of the LM2671N-12/NOPB makes it ideal for applications with environmental constraints such as portable computer systems, automotive systems and other industrial applications. The low power consumption and minimal standby current ensure that the LM2671N-12/NOPB is an excellent solution for applications where power supply efficiency is a factor. The high-side N-Channel MOSFET provides very low drop-out voltage and output voltage regulation enabling it to maintain a higher output current without increasing the output voltage.
