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.
