LM3352-3.0EVAL is an evaluation board specially designed for the latest buck DC/DC converter with integrated FET – LM3350. The board has more features which involve one of the most power-efficient buck switching regulator ICs. It has the capability to provide excellent transient response, very low output ripple, extended operating temperature range and high efficiency. This article discusses the application fields and working principles of the board.

Applications

The LM3352-3.0EVAL board is designed to be used in a wide range of applications. It can be used in systems that require high efficiency, extended temperature range operation, low output ripple and quick transient response. It can also be used in extreme operating environment such as portable applications and high temperature applications. Due to its high efficiency, the LM3352-3.0EVAL can help reduce system power losses efficiently, while its wide temperature range enables it to operate in environments with harsh thermal conditions. Its low output ripple ensures that the system would run reliably with low noise, and its quick transient response offers stable output even under high and heavily loaded conditions.

Working Principles

The LM3352-3.0EVAL board is designed to use the integrated FET, LM3350, as the regulator. The regulator claims to provide a full array of features such as low dropout performance, high current implement, fast transient response, a low output ripple of 1mV and wide temperature range. Additionally, the LM3350 regulator also performs other functions such as power regulation, over voltage and over current protection, inrush current control, soft start function and short circuit protection.

The LM3350 regulator uses pulse width modulation (PWM) switching to regulate its output voltage. This is achieved by using a fixed frequency oscillator to modulate the width of the output current pulses to keep the output voltage constant. When the output voltage falls below the set threshold, the PWM increases the pulse width and output current until it reaches the set voltage. The output voltage is then maintained by adjusting the pulse width as per the load changes.

The LM3352-3.0EVAL board is also equipped with a voltage sense module that senses the input and output voltages. The sensing pins are connected to the input and output pins of the voltage regulator to monitor the input and output voltages of the circuit. The feedback pins are then connected to the potentiometers to set the output voltage accurately.

Conclusion

The LM3352-3.0EVAL board is a highly efficient buck DC/DC converter. It has integrated FET, LM3350, for power regulation and over voltage and over current protection, inrush current control, soft start function and short circuit protection. The board also contains a voltage sense module is for monitoring input and output voltages. Therefore, the LM3352-3.0EVAL board is ideal for applications that require high efficiency, extended temperature range operation, low output ripple and quick transient response.
