Two integrated nanopower PMICs for IoT applications, the DA9070 and DA9073, have been released by Dialog. The PMICs are designed for ‘always-on’ IoT devices such as fitness trackers, smartwatches and smart home products which are expected to spend less time tethered to a charger, while expanding feature sets present new challenges to battery life.

LDO extends portable devices’ battery life
Prolonging battery life by up to four times longer than traditional low quiescent (Iq) LDOs, the MCP1811 is a linear low dropout (LDO) regulator available from Microchip. It enables reduced standby power consumption in remote, battery-powered sensor nodes and also enables faster response times and transient response for IoT, wearable and remote designs, says Microchip.
Powercast shrinks Powerharvester wireless power receiver
Powercast has produced a smaller Powerharvester wireless power receiver and RF-to-DC converter chip (the PCC114) for its Powerharvester chipset. The chipset is comprised of a wireless power receiver chip and complementary boost converter IC and is embedded in a device to harvest RF energy.
3V prismatic supercapacitors support coin cells and saves BoM
Peak power support to 3V coin cell batteries is provided by the 3V thin prismatic supercapacitors announced by Cap-XX. They also save on bill of materials (BoM) costs as they eliminate the need for a 2.7V low dropout (LDO) regulator for less expensive, smaller, more energy-efficient designs with extended battery life, says the company.
