Product Overview

The LTC3203EDD-1#PBF is a low noise dual mode step-up Charge Pump capable of driving loads up to 500mA from a 2.7 to 5.5V input. It uses a switched capacitor charge pump to boost VIN to a regulated output voltage. Low external parts count (two flying capacitors and bypass capacitors at VIN and VOUT) make the LTC3203 family ideally suited for small, battery-powered applications. Built-in soft-start circuitry prevents excessive inrush current during start-up. High switching frequency enables the use of small external capacitors. The LTC3203-1 feature Burst Mode® operation at light load to achieve high efficiency. The LTC3203-1 has an user selectable fixed output voltage of 4.5V or 5V to power LEDs or logic circuits.
  • Selectable dual mode operation (1:1.5 or 1:2)
  • High output current (up to 500mA)
  • Low noise constant frequency (1/0.9MHz) operation
  • User selectable fixed output voltages (4.5 or 5V)
  • Automatic Burst Mode® operation with IQ ~ 120µA
  • Soft-start limits inrush current at turn-on
  • Short-circuit/thermal protection
  • Shutdown disconnects load from input
  • <1µA Shutdown current

Applications

LED Lighting, Communications & Networking, Consumer Electronics, Multimedia, Power Management
