The LM2767M5 is a member of the DC DC Switching Regulators family of PMIC (Power Management IC) voltageregulators. This highly integrated switching regulator is designed for use in various DC/DC conversion applications including those in low power, portable and battery-powered systems. The device includes a wide range of features, including an adjustable output voltage, fixed frequency pulse width modulation (PWM) control and constant current limiting. In addition, the device has a low input/output voltage differential and built-in over voltage protection (OVP), making it uniquely suited for monitoring and controlling voltage rail applications.

The LM2767M5 is an adjustable, low dropout (LDO) regulator that features an adjustable output voltage range of 0.8V to 17V. The device includes a PWM control block, an internal feedback loop and an adjustable output current limit. The PWM control block is designed to produce a high efficiency, constant frequency PWM waveform that drives the internal MOSFET switch. The PWM frequency is adjusted by an external resistor and can range from 200 Hz to 500 kHz. The feedback loop is designed to maintain the output voltage at its programmed level. The adjustable output current limit can be programmed in two ways: by an external manual or by a digital signal.

The LM2767M5 includes an integrated over voltage protection (OVP) circuit. This circuit monitors the output voltage and limits the output to the OVP limit if the output voltage exceeds the preset value. In addition, the device includes a wide input voltage range and a low input/output voltage differential. The device also includes an enable input, allowing it to be turned on and off from the digital logic.

The LM2767M5 is designed for use in a variety of different DC/DC conversion applications. It can be used in a wide range of systems, including those requiring isolation, high load current requirements and low power consumption. Examples of applications for the LM2767M5 include battery chargers, power adapters, buck and boost converters, low voltage DC-DC conversions, motor control, and other low power applications.

The device is available in a small 6-pin SOIC package and operates in a wide temperature range from -40 to +85 degrees Celsius. All in all the LM2767M5 is a efficient and cost effective solution for DC/DC conversion that delivers superior performance with minimal external components.
