Analog Devices Inc./Maxim Integrated MAX1999EEI-T is a highly integrated PMIC featuring four voltage regulators in a 28-QSOP package. This component is designed for applications requiring both synchronous buck and linear regulation, offering two step-down (buck) outputs and two linear (LDO) outputs. The synchronous buck converters operate within a switching frequency range of 200kHz to 500kHz, providing efficient power conversion. The LDO outputs are capable of delivering up to 100mA at 3.3V. The device includes a sequencer and operates from a 4.5V to 24V supply range, with a surface mount configuration suitable for compact designs. This versatile power management solution is commonly employed in industrial automation, consumer electronics, and communication systems. The MAX1999EEI-T is supplied on tape and reel for automated assembly.
