Power management integrated circuit (PMIC), also known as an energy management IC, is a semiconductor integrated circuit (IC) used to manage the power micro-electronic circuits. As power consumption decreases and device complexity increases, the need for low-power, high-efficiency power management circuitry becomes paramount. PMICs provide the necessary voltage and load regulation necessary to ensure the integrity of microelectronic devices as they turn on, transition, and turn off. This can be critical in applications ranging from powering small electronic devices in wearables to industrial motor controllers.

LED drivers, also known as lighting power supplies or light fixtures, are critical components in lighting applications. LEDs have become popular for their high efficiency and long lifetime, and drivers provide the essential power for the LEDs to emit light, maximize the performance of the LEDs, and provide a reliable connection between the fixture and the light source. A driver can be easily integrated into an LED application for seamless power delivery and maximum performance.
