The LM2767M5/NOPB is a monolithic switching voltage regulator that can provide a non-isolated output voltage. This voltage regulator is designed to work across a wide range of input voltages and provide a stable output while also offering power saving features. The LM2767M5/NOPB is specifically designed for use with portable and mobile devices, providing high efficiency always-on battery charging for devices such as car navigation systems, mobile phones, two-way radios, etc. This device can provide up to 5A of continuous current and is capable of switching frequencies up to 500kHz, allowing for more efficient and reliable operation.

The voltage regulator is easy to use and integrates several features for maximum device performance. The voltage regulator includes synchronous rectification for improved efficiency, a built-in current-limit circuit for current overload protection, and a built-in thermal control circuit to maintain the appropriate temperature without the need for external components. Additionally, the compact package size and low-profile design make the LM2767M5/NOPB an ideal choice in applications where board space is at a premium. The general purpose voltage regulator also features a shutdown mode, allowing the device to enter a low power state when not in use.

The LM2767M5/NOPB operates by controlling the output voltage by switching the power switch in a PWM (pulse width modulation) manner. This voltage regulator uses a feedback loop to compare the actual output voltage to the desired output voltage. The difference between these two values is then used to control the duty cycle of the power switch. When the power switch is turned on, current flows from the input voltage source, through the power switch, and to the output capacitor. When the power switch is turned off, the output capacitor is allowed to charge, providing the regulated output voltage.

The input voltage source can operate from a wide range of sources—4.5V to 17V for the LM2767M5/NOPB—and supports a wide range of output voltages. The output voltage can be adjusted to any value between 0.8V and 17V. The LM2767M5/NOPB can also operate as a buck, boost, or buck/boost regulator, depending on the specific application. Additionally, the voltage regulator features both single- and dual-channel outputs, enabling easy configuration for powering multiple loads.

The LM2767M5/NOPB is an ideal choice for applications that require high efficiency, wide input and output voltage ranges, and low-profile designs. The synchronous rectification, current limit circuit, and thermal control circuit offer maximum device reliability and performance, while the wide operating range and multiple output channels make the voltage regulator configurable for a variety of applications. The LM2767M5/NOPB is a versatile and cost-effective solution for reliable and efficient power supply applications.
