Product Overview

LTC®3499 is a synchronous, fixed frequency step-up DC/DC power converter with integrated reverse battery protection that protects and disconnects the device and load when the battery polarity is reversed while delivering high efficiency in a small (3mm × 3mm) DFN package. True output disconnect eliminates inrush current and allows zero load current in shutdown. The device features an input voltage range of 1.8V to 5.5V enabling operation from two alkaline or NiMH batteries. The switching frequency is internally set at 1.2MHz allowing the use of tiny surface-mount inductors and capacitors. A minimal number of external components are required to generate output voltages ranging from 2V to 6V. This features automatic Burst Mode operation to increase efficiency at light loads. Applications includes medical equipment, digital cameras, MP3 players, handheld instruments.
  • Inrush current controlled during start-up, output disconnect in shutdown
  • Tiny external components, overvoltage protection
  • Typical minimum start-up voltage is 1.6V (TA = 25°C, VIN = 2.4V)
  • FB voltage range from 1.195 to 1.245V (TA = 25°C, VIN = 2.4V)
  • Maximum duty cycle is 85% (typ, TA = 25°C, VIN = 2.4V)
  • Typical frequency accuracy is 1.2MHz (TA = 25°C, VIN = 2.4V)
  • Typical error amplifier source current is -5µA (TA = 25°C, VIN = 2.4V)
  • Maximum VOUT reverse-battery current is 5µA (VOUT = 0V, VIN = VSHDN = VSW = -6V, TA = 25°C)
  • 8-lead plastic MSOP package
  • Temperature rating range from -40°C to 85°C
