DC Switching Voltage Regulators

The LM34927MR/NOPB is a highly integrated, high-voltage, step-down (buck) regulator from Texas Instruments. It is designed to provide efficient and precise voltage regulation for a wide range of applications, including industrial, medical, and automotive systems.

Description:

The LM34927MR/NOPB is a monolithic, high-voltage, step-down regulator that integrates a high-side and low-side MOSFET, as well as a synchronous rectifier. It features a wide input voltage range of 4.5V to 60V and can deliver an output voltage as low as 0.9V. The device is available in a thermally enhanced 20-pin HTSSOP package.

Key Features:

1. Wide input voltage range: 4.5V to 60V
2. Output voltage as low as 0.9V
3. High efficiency: up to 96% due to synchronous rectification and low quiescent current
4. Integrated high-side and low-side MOSFETs
5. Synchronous rectification for improved efficiency
6. Programmable soft-start and tracking
7. Precision 1.2% reference for accurate output voltage regulation
8. Programmable frequency from 100kHz to 1MHz
9. Internal compensation for easy external component selection
10. Over-current protection, thermal shutdown, and open-loop protection
11. Enable and power-good pins for system-level control and monitoring
12. Available in a 20-pin, 4mm x 5mm HTSSOP package
