Product Overview

The LTC3240EDC-3.3#TRMPBF is a step-up/down DC/DC charge-pump Converter that produces a fixed regulated output voltage of 3.3/2.5V over a wide input voltage range (1.8 to 5.5V). With input voltages greater than the regulated output voltage the LTC3240 operates as a low dropout regulator. Once the input voltage drops within 100mV of the regulated output voltage the part automatically switches to step-up mode. In step-up mode the LTC3240 operates as a constant frequency (1.2MHz) doubling charge-pump. It features low no load operating current (65µA typical) and ultralow operating current in shutdown (<1µA). Built-in soft-start circuitry prevents excessive inrush current during start-up. Thermal shutdown and current-limit circuitry allow the parts to survive a continuous short-circuit from VOUT to GND. It requires only three tiny external ceramic capacitors for an ultra-small application footprint.
  • Automatic mode switching
  • Low dropout regulator operation in step-down mode
  • Built-in soft-start reduces inrush current
  • Shutdown disconnects load from input
  • Short-circuit/thermal protection
  • 65µA Low no-load quiescent current
  • Output current up to 150mA
