Product Overview

The LT1616ES6#TRMPBF is a 1.4MHz step-down Switching Regulator with internal 0.6A power switch. The wide input range of 3.6 to 25V makes the LT1616 suitable for regulating a wide variety of power sources, from 4-cell batteries and 5V logic rails to unregulated wall transformers and lead-acid batteries. Its high operating frequency allows the use of tiny, low cost inductors and ceramic capacitors. With its internal compensation eliminating additional components, a complete 400mA step-down regulator fits onto 0.15 square inches of PC board area. The constant frequency current mode PWM architecture and stable operation with ceramic capacitors results in low, predictable output ripple. Current limiting provides protection against shorted outputs. The low current (<1µA) shutdown provides complete output disconnect, enabling easy power management in battery-powered systems.
  • Wide input range
  • 5V at 400mA from7 to 25V input
  • 3.3V at 400mA from 4.7 to 25V input
  • Fixed frequency 1.4MHz operation
  • Uses tiny capacitors and inductors
  • Internally compensated
  • Low shutdown current (<1µA)
  • Low VCESAT switch (220mV at 300mA)
