The LM2512ASNX from Texas Instruments is a high-performance, versatile and robust device designed for a variety of applications.

• Description: The LM2512ASNX is a monolithic, high-efficiency, step-up DC-DC converter.
• Function: It is designed to drive up to 10 white LEDs in series from a Li-Ion cell.
• Current: This converter provides a constant current to regulate the LED brightness and uses a single inductor for operation.
• Switch: The device has an internal 40V switch and can operate @ a switch frequency of up to 1.6 MHz.
• Regulator: Equipped with a high-efficiency boost regulator.
• MOSFET: The device also features a built-in power MOSFET of 40V, 0.5A that enhances its performance and efficiency.
• Brightness Control: The brightness of the LEDs can be adjusted with a pulse width modulated (PWM) signal @ the enable pin.
• Voltage: It also has a low feedback voltage of 200mV that minimizes power dissipation, thereby improving efficiency.
• Safety Features: Includes safety features such as thermal shutdown, LED open protection, and LED short protection.
• Temperature Range: It operates over a wide temperature range from -40°C to 85°C.
• Package: The device comes in a tiny 10-bump DSBGA package.
