ADP5600ACPZ-R7

ADP5600 is an interleaved charge pump inverter with an integrated, negative, low dropout (LDO) linear regulator. The interleaved charge pump inverter exhibits reduced output voltage ripple and reflected input current noise over conventional inductive or conventional capacitive based solutions. The integrated LDO provides a rail with good regulation at sufficient power supply rejection ratio (PSRR). This device's charge pump operates via resistor programming or external clock synchronization at switching frequency range of 100KHz to 1MHz. Operating at a higher switching frequency allows the use of small input, output, and fly capacitors. To combine the high switching frequency with internal field effect transistors (FETs), compensation, and soft start gives a best-in class total solution size for negative rail generation. It is used in application such as powering the negative rail on bipolar/split supply ADC/DAC/AMP/mux applications etc.
