LTC3203-1 - 500mA Output Current Low Noise Dual Mode Step-Up Charge Pumps

Download the LTC3203-1 datasheet PDF. This datasheet also covers the LTC3203 variant, as both devices belong to the same 500ma output current low noise dual mode step-up charge pumps family and are provided as variant models within a single manufacturer datasheet.

Key Features

  • Selectable Dual Mode Operation: 1:1.5 or 1:2.
  • High Output Current: Up to 500mA.
  • Low Noise Constant Frequency (1MHz/0.9MHz) Operation.
  • VIN Range: 2.7V to 5.5V.
  • Adjustable Output Voltage (LTC3203/LTC3203B).
  • User Selectable Fixed Output Voltages: 4.5V or 5V (LTC3203-1 and LTC3203B-1).
  • Burst Mode® Operation with IQ ~ 120µA (LTC3203/LTC3203-1).
  • Constant Freqency Operation at All Loads (LTC3203B/LTC3203B-1).
  • Soft-Start Limits Inrush Current at Turn-On.
