Maxim’s nanoPower boost regulator claims industry’s longest battery life
Maxim’s nanoPower boost regulator claims industry’s longest battery life: Claiming the industry’s longest battery life and the smallest form factor for use in wearable and consumer IoT designs, the MAX17222, from Maxim features 300nA IQ and 95 per cent peak efficiency. It reduces solution size by up to 50 per cent, adds the company.
The MAX17222 nanoPower boost regulator from Maxim Integrated Products, has quiescent current (IQ) of only 300nA. The 0.4 to 5.5V input, 1.8 to 5.0V output boost regulator has 500mA input current limit, and reduces solution size by up to 50 per cent compared to similar products, claims the company, and offers 95 per cent peak efficiency to minimise heat dissipation. The resulting benefits make the nanoPower boost regulator suitable for wearable devices.
Microcontrollers simplify wearable design and extend battery lif
Two microcontrollers from Maxim Integrated, the MAX32630 and MAX32631, increase processing speed, maintain small package sizes and extend battery life for wearable devices, claims the company.
