Maximum output current: −100 mA Integrated power MOSFETs Programmable charge pump switching frequency range 100 kHz to 1 MHz Frequency synchronization via SYNC pin Precision enable and power good Internal soft start Output short-circuit and overload protection Shorted charge pump fly capacitor protection Integrated LDO output discharge resistor 16-lead, 4 mm × 4 mm LFCSP The 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). The ADP5600 charge pump operates via resistor programming or external clock synchronization at switching frequency range of 100 kHz to 1 MHz. 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. The ADP5600 also features comprehensive fault protection for robust applications. These protections include overload protection, shorted fly capacitor protection, undervoltage lockout (UVLO), and thermal shutdown. For easy sequencing, the ADP5600 has a power-good pin.
