The LM2660MX/NOPB is the latest family of integrated power solutions from Texas Instruments, designed for mobile and consumer applications. This product family is ideal for applications that require high power efficiency, small size, and low power consumption. The LM2660MX/NOPB provides a complete power solution that is easy to use and requires minimal external components. It integrates a power MOSFET, two phase switched mode power supply (SMPS) controller, thermal protection, low quiescent current MOSFET driver, and current-limiting circuit in a single package.

The LM2660MX/NOPB is part of the family of DC-DC switching regulators, which are used to regulate a wide range of voltages and currents. DC-DC switching regulators are commonly used in applications where a power supply needs to be efficiently converted from one voltage level to another. The output of the DC-DC switching regulator can be adjusted to meet the requirements of the application. In addition, this type of regulator is highly efficient and can be used in applications where the input voltage source is not always constant.

The LM2660MX/NOPB features both synchronous and pulse width modulation (PWM) modes. The synchronous mode is suitable for multiple output voltages and can be used in hot swap applications. The PWM mode is suitable for single output applications as well as applications where multiple outputs are not required. Both modes enable the switching regulator to operate in peak efficiency and minimize losses.

The LM2660MX/NOPB also incorporates a POWER_GOOD output signal, which can be used to indicate to the user or microcontroller when the output is within the regulation range. The device also provides thermal shutdown protection, enabling safe operation even in extreme conditions.

The LM2660MX/NOPB application field includes power conversion from one voltage range to another in a variety of applications such as mobile phones, PDAs, digital cameras, MP3 players, notebooks, and small appliances. The device is ideal for use in portable, battery powered applications where high efficiency, low power consumption, and small size are required.

The LM2660MX/NOPB works on the principle of converting input voltage to a different output voltage using a high efficiency switch mode power supply controller. The LM2660MX/NOPB has two high speed terminals that are connected to two low speed terminals. The input is applied to the high speed terminals, while the low speed terminals are connected to the output. A switching signal is generated by the power supply controller on the high speed terminals to drive the power MOSFET. This signal is an oscillating waveform with a frequency determined by the nature of the input voltage.

The frequency of the signal determines the efficiency of the power conversion process. When the frequency reaches a certain level of stability and the output voltage is within the specified range, the POWER_GOOD signal is asserted and the LM2660MX/NOPB enters into regulation. The input power is then converted into the required output voltage with improved efficiency.

The LM2660MX/NOPB is designed with an advanced power supply controller and a current-limiting circuit. The power supply controller monitors the input and output voltages and performs the necessary calculations to determine the frequency and the duty cycle of the switching signal. This is then used to drive the MOSFETs, controlling the output voltage. The current-limiting circuit helps to protect the system from damage caused by excessive current.

The LM2660MX/NOPB is designed to provide power conversion efficiency up to 90%. It is suitable for a variety of applications, such as mobile phones, PDAs, digital cameras, MP3 players, notebooks, and other small appliances. With its small size, low power consumption, and high efficiency, the LM2660MX/NOPB is ideal for use in battery powered and portable applications.
