Product Overview

The LTC3265EDHC#PBF is a low noise dual polarity DC to DC converter with boost and inverting charge pump in 18 pin DFN package. This inductorless (charge pump) high voltage DC to DC converter includes boost charge pump, inverting charge pump, two low noise positive and negative LDO post regulators. The boost charge pump powers the positive LDO post regulator while the inverting charge pump powers negative LDO regulator. The LDO output voltages can be adjusted using external resistor dividers. The regulated step up charge pump employs low quiescent current burst mode operation or low noise constant frequency mode. During burst mode operation, the boost charge pump regulates its output to 0.94 x 2 x VIN_P while inverting charge pump regulates its output (VOUT-) to -0.94 x VIN_N.
  • Programmable oscillator frequency from 50KHz to 500KHz
  • Boost charge pump generates 2 x VIN_P (VIN_P range from 4.5V to 16V)
  • Inverting charge pump generates -VIN_N (VIN_N range from 4.5V to 32V)
  • Low noise positive LDO post regulator provides up to 50mA output current
  • Low noise negative LDO post regulator provides up to 50mA output current
  • 135µA quiescent current in burst mode operation (both LDO regulators are in on condition)
  • Stable with ceramic capacitors
  • Short circuit and thermal protection
  • Operating junction temperature range from -40°C to 125°C
