The L4960 is a monolithic power switching regulator manufactured by STMicroelectronics (ST). Below are the factual specifications, descriptions, and features of the L4960:

Specifications:

• Output Voltage Range: 5.1V to 40V (adjustable)
• Output Current: Up to 2.5A (with proper heat sinking)
• Input Voltage Range: 9V to 46V
• Switching Frequency: 100kHz (fixed)
• Efficiency: Up to 90%
• Dropout Voltage: Typically 1.1V (at 2.5A)
• Operating Temperature Range: -40°C to +125°C
• Package: Multiwatt15 (through-hole)

Descriptions:

• The L4960 is a step-down (buck) switching regulator that provides high efficiency and precise voltage regulation.
• It integrates a PWM controller, power switch, and protection circuits into a single chip.
• Designed for high-power applications, it requires minimal external components.
• Features current limiting, thermal shutdown, and soft-start for robust operation.

Features:

• Adjustable Output Voltage via external resistors.
• High Efficiency (up to 90%) due to switching topology.
• Built-in Protection Circuits:
• Overcurrent Protection
• Thermal Shutdown
• Soft-Start Function (reduces inrush current)
• Low Dropout Voltage (suitable for battery-powered applications).
• Fixed-Frequency PWM Operation (100kHz) for stable performance.
• Wide Input Voltage Range (9V to 46V).
• External Sync Capability (for noise-sensitive applications).

The L4960 is commonly used in power supplies, industrial systems, automotive electronics, and battery chargers due to its high efficiency and reliability.
