12V Step-Up Voltage Regulator U3V70F12

Overview: This powerful synchronous switching boost regulator efficiently generates an output voltage of 12 V from an input voltage as low as 2.9 V while using an input current as high as 7 A. This regulator features reverse voltage protection, and unlike most boost regulators, it offers a true shutdown option that turns off power to the load.

Features and specifications:

• Input voltage: 2.9 V to 12 V
• Output voltage: 12 V with 4% accuracy
• True shutdown option turns off power to the load
• Typical efficiency of 80% to 95%, depending on input voltage and load (see the Typical efficiencies and output currents section below for performance graphs)
• 10 A switch allows for:
  • Instantaneous input currents up to 10 A
  • Input currents up to 7 A for several seconds
  • Input currents up to 6 A for prolonged durations
• low quiescent current
• Integrated protections:
  • Reverse voltage protection
  • Short-circuit protection with hiccup recovery
  • Over-temperature shutoff
  • Under-voltage lockout (typical thresholds are 2.4 V falling, 2.8 V rising)
  • Cycle-by-cycle input current limiting to 10 A
• Compact size: 1.6″ × 0.6″ × 0.18″ (40.6 × 15.2 × 4.6 mm)
• Weight: 3.5 g
• Two mounting holes for #2 or M2 screws
• Smaller holes for 0.1″ header pins and larger holes for terminal blocks offer several options for connecting to the board
