Science | Ten key advantages of power management integrated circuits
Power Management Integrated Circuits (PMICs) bring many benefits to the devices they are integrated into. The most important advantages you will gain by using Power Management Integrated Circuits are as follows:
0 1
Configurability and flexibility: Today’s power management ICs are very flexible – one design can be used for multiple applications through programming (firmware) updates. Default values, sequencing, and other parameters can all be programmed. This reduces manufacturers’ time to market and bill of materials costs.
0 2
Multiple output rails: Today’s power management integrated circuits (PMICs) are capable of providing low, medium, and high voltage supplies. There are multiple independent voltage rails in a PMIC along with multiple buck, boost, buck-boost converters, low dropout linear regulators (LDOs), and load switches to perform many functions.
0 3
Small Solution: The PMIC is small and provides all functions in one package, which is an improvement over the individual discrete solutions used previously.
0 4
Easy to customize: PMICs are configurable and programmable, so the same device can be reprogrammed for multiple solutions. They can also be configured with a variety of regulator device technologies.
0 5
Reduced external component count: PMICs are complete solutions with integrated voltage regulation functions, all in one package. Reduced component count results in shorter design time, smaller size, and lower cost.
0 6
Reduce design costs: PMICs are system-in-package solutions. They reduce power supply current consumption, shorten design time, and reduce component count, providing customers with optimal solutions without hardware customization.
0 7
Highly integrated: Other functions such as analog-to-digital converters (ADCs) and coulomb counters can be integrated into the PMIC, providing an easy and reliable way to monitor power systems and critical signals.
0 8
Faster time to market: PMICs allow for customization without the need to design new hardware. With quality qualified and reliable parts, customers’ time to market can be significantly shortened.
0 9
Reduced EMI: Small size and integration inherently reduce EMI. The PMIC’s configurability and optimized power metal oxide semiconductor field effect transistors (MOSFETs) also reduce EMI. This design reduces the hassle of EMI troubleshooting, reduces component count, minimizes shielding, and enables faster EMI certification.
10
Multiple uses: PMICs can be used in many applications ranging from integrated motor control to battery management, modular power supply units, power-off protection devices, and DC-to-DC converters.
