Introduction

AI Translation

The LTC3290 is a high voltage boost charge pump with a wide 4.5V to 55V input voltage range that can deliver up to 50mA of output current. When the VSET pin is grounded, the LTC3290 operates as a standard boost charge pump, boosting the VOUT output to a maximum of the sum of the VIN and VAUX input supplies. An external resistor divider can be used on the VOUT, FB and GND pins to set the output voltage to any value between VIN and VIN + VAUX with hysteretic Burst Mode operation. Alternatively, the device can be configured in a VIN tracking mode, in which the VOUT pin regulates at a fixed offset above the VIN pin. The offset voltage is programmed with external resistors, one from the VOUT to the VSET pin and the other from the FB pin to GND. The maximum output voltage is limited to VIN + VAUX. The LTC3290 is available in a thermally enhanced 10-pin MSOP package.
