Product Overview

The L4960 is a Monolithic Power Switching Regulator IC delivering 2.5A at a voltage variable from 5 to 40V in step down configuration. Efficient operation at switching frequencies up to 150kHz allows a reduction in the size and cost of external filter components. This device is particularly suitable for battery-powered equipment, reducing consumption and prolonging battery-life. Each type employs internal current limiting, anti-saturation circuit, thermal shutdown and safe area protection.
  • Precise (±2%) on-chip reference
  • High switching frequency
  • Very high efficiency (up to 90%)
  • Very few external components
  • Soft start
  • Internal limiting current
  • Thermal shutdown
  • Short-circuit protection
  • Reverse polarity protection
