The bq24650 device from Texas Instruments is a highly integrated switch-mode battery charge controller. It provides input voltage regulation, which reduces charge current when input voltage falls below a programmed level. When the input is powered by a solar panel, the input regulation loop lowers the charge current so that the solar panel can provide maximum power output.

Dual isolated output bias power supply with zero standby consumption
This reference design is a 15-W bias power supply with two isolated outputs (12V/1.125A and 3.3V/0.3A) and a total standby power consumption of 4mW under a 220V AC input. The controller uses primary-side regulation (PSR) and detects a wake-up signal from the UCC24650 secondary-side voltage-droop monitor for improved transient response to large load steps.
