The LM2577T-12/NOPB from Texas Instruments is a monolithic integrated circuit that provides all the active functions for a step-up (boost) voltage regulator, capable of driving a 3A load with excellent line and load regulation. This versatile device is designed to be used in a wide variety of applications, including on-card regulation for elimination of noise and distribution problems associated with single-point regulation.

Featuring a fixed output voltage of 12V, the LM2577T-12/NOPB is a reliable choice for applications requiring a regulated power supply from a lower voltage source. Its simple external components requirement makes it easy to design with, and its 52 kHz fixed frequency internal oscillator ensures a small-sized passive filter for the output.

Key Features:

• 3.0A Output Current
• Requires Few External Components
• Fixed 52 kHz Frequency Internal Oscillator
• TTL Shutdown Capability
• Low Power Standby Mode
• High Efficiency
• Uses Readily Available Standard Inductors
• Thermal Shutdown and Current Limit Protection

The LM2577T-12/NOPB also offers the convenience of a TTL-compatible shutdown mode, which significantly reduces power consumption when the device is not in use. Additionally, the regulator is equipped with protection features like thermal shutdown and current limit protection to safeguard the device and the load from potential damage.

Thanks to its high efficiency and robust design, the LM2577T-12/NOPB is suitable for a variety of applications, including but not limited to simple high-efficiency step-up regulators, positive to negative converters (Buck-Boost), and voltage doublers in configurations. Its standard TO-220 package ensures compatibility with a wide range of heat-sinking options.

With its combination of features and ease of use, the LM2577T-12/NOPB is an excellent choice for designers looking to implement a compact, efficient, and reliable power solution.
