Download Datasheet Visit Manufacturer Site View Pricing & Stock

The LTC3265 is a low noise dual polarity output power supply including a boost charge pump, an inverting charge pump and 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 the negative LDO regulator. Each LDO can provide up to 50mA of output current. The LDO output voltages can be adjusted using external resistor dividers.The charge pumps employ low quiescent current Burst Mode operation or low noise constant frequency mode. During Burst Mode operation, the boost charge pump regulates its output (VOUT +) to 0.94 • 2 • VIN_P while the inverting charge pump regulates its output (VOUT –) to –0.94 • VIN_N. In Burst Mode operation the LTC3265 draws only 135μA of quiescent current with both LDOs on. In constant frequency mode, the boost and inverting charge pumps produce outputs equal to 2 • VIN_P and –VIN_N respectively and operate at a fixed 500kHz or to a programmed value between 50kHz to 500kHz using an external resistor. The LTC3265 is available in low profile 3mm × 5mm × 0.75mm 18-lead DFN and thermally enhanced 20-lead TSSOP packages.

Demonstration Circuit 2235A has boost and inverting charge pumps each with a low noise LDO post regulator featuring the LTC®3265EDHC. The LTC3265 operates with an input voltage from 4.5V to 16V for the boost charge pump and from 4.5V to 32V for the inverting charge pump. The demo board provides selectable LDO± output set magnitudes of 5V, 15V, and 24V for each polarity. The demo board also provides the means to select between low power Burst Mode® operation or low noise constant-frequency PERFORMANCE SUMMARY SYMBOL
