LM2675M-5.0

LM2675M-5.0 is a DC-DC switching regulator, which belongs to the power management integrated circuit (PMIC). This chip is specifically designed to provide maximum flexibility and performance in the area of DC-DC switching regulator applications.It is mainly used to provide point of load (POL) voltage regulation. The device comes in an 8Pin SOIC package and requires an operating temperature range of 0℃to 70℃.

LM2675M-5.0 provides a minimum voltage of 5.0V and a maximum input voltage of 28V. The device has a low start-up and low shutdown current. It has a low voltage operation power saving mode, that eliminates the need for a discrete startup control circuit. The maximum continuous output current is 1.0A and the internal power MOSFET has a maximum efficiency of up to 95%.

The device can obtain an input current between 20µA and 1.75A and an output current of 800mA at a temperature range of 0℃to 70℃. The integrated power switch has a minimum on resistance of 0.60Ω and a maximum on resistance of 2.5Ω. The device can operate in voltage mode or PWM mode and it has a switching frequency of either 200kHz or 500kHz.

LM2675M-5.0 is widely used in the field of battery chargers, mobile device charging, battery backup systems, portable instrumentation and many other fields.The working principle of this device is to convert a certain level of DC voltage or current at the input to make it into a higher-level or lower-level voltage or current at the output. This is done by controlling a switch, which is usually an MOSFET transistor, on and off at a rate determined by the frequency of operation.The switch will pass the input voltage to the output when it is on and block it when it is off. The control circuit will then detect the output voltage and adjust the frequency of the switch accordingly in order to maintain the desired output voltage.

In summary, the LM2675M-5.0 is a highly integrated and cost effective DC-DC switching regulator device which is ideally suited for applications in battery chargers, mobile device charging, battery backup systems, portable instrumentation and many other power-sensitive applications. It has a wide range of operating temperature and it can operate in voltage mode or PWM mode with a switching frequency of either 200kHz or 500kHz.
