Dialog Semiconductor unveiled its first nanopower PMICs, the DA9230 and DA9231. The two new PMICs are the smallest of their class on the market, enabling longer battery operating time and enhanced efficiency for always-on IoT applications, consuming only 750 nA of total input current with the buck enabled and under no load conditions.
Other PMICs on offer either lack multiple rails and I2C configurability in one chip, or take up twice the size as Dialog’s offering. Offered in a small footprint to fit into space-constrained applications, the PMICs improve battery life with ultra-low quiescent current, high-efficiency and configurability.
Designed to support current and future platforms, the DA9231 features a 300 mA buck together with a 100 mA LDO and the DA9230 features a standalone buck. For both devices, the buck regulator’s minimum output voltage of 0.6 V enables powering advanced 14 or 10 nm geometry SOCs. With a minimum supply voltage of 2.5 V, these devices are also ready to support upcoming silicon anode battery technology.
