Power Management ICs

Power Electronics and Power Systems

Power management ICs are used to manage the accurate power flow in portable and handheld devices, such as cell phone power amplifiers and LED display, CPU, DRAM, Graphics, High Speed I/O and USB. In addition, under-voltage or other fault conditions are monitored to prevent damage to the system. The soft-start feature reduces stress on power supply components and increase product reliability. Implementation is typically done using analog integrated circuits but there is a strong trend to move towards digital or mixed signal implementation.
