Product Overview

The LTC3261EMSE#PBF is a high voltage low quiescent current inverting Charge Pump that operates over a wide 4.5 to 32V input range and is capable of delivering up to 100mA of output current. The charge pump employs either low quiescent current Burst Mode® operation or low noise constant frequency mode. In Burst Mode® operation the charge pump VOUT regulates to -0.94 VIN and the LTC3261 draws only 60µA of quiescent current. In constant frequency mode the charge pump produces an output equal to -VIN and operates at a fixed 500kHz or to a programmed frequency between 50 to 500kHz using an external resistor. The LTC3261 has built in soft-start circuitry to prevent excessive current flow during start-up. It also has built-in short-circuit current limit as well as over-temperature protection. Due to high switching frequency and high transient currents produced by LTC3261, careful board layout is necessary for optimum performance.
  • Inverting charge pump generates -VIN
  • 60µA Quiescent current in Burst Mode® operation
  • Charge pump output current up to 100mA
  • 50 to 500kHz Programmable oscillator frequency
  • Short-circuit/thermal protection
